FOREWORD

JOIN HANDS WITH SCE Dear Engineers

‫السالم علیکم و رمحتہ ہللا ورباکتہ‬

T

echnical and artistic excellences are very desirable features but in addition, there are other elements required for publication of The JOURNAL to fulfill its object completely. Of these other elements one, and perhaps the most important, is that our Magazine should convey a direct—a human—interest to as many individual members of the community as possible. There is a social as well as a business side to our relations with each other, and the cultivation of the human touch adds to the happiness and contentment of members when engaged in the performance of their multifarious duties. I congratulate the Editorial Board for presenting and promoting this idea. I am confident that this issue will be yet another milestone in the Editorial Board’s pursuit of excellence. All regions of IEP-SAC have gone extra length to extend their helping hand not only to the victims of such calamities as the 2005 earthquake and 2010 floods but also by instituting and enlarging on a continuous basis, an impressive scholarship program for needy engineering students of Pakistani engineering universities in the public sector. Our steps may be small but they are giant leaps for the needy students. The absolute volunteer services of the council members at the three regions—Central, Eastern, and Western—is the vehicle for making this success a possibility. Without their sheer hard work and dedication, our programs on the technical and social fronts could not have been held so successfully, and as always. I would like to salute them all. I call upon the community to come forward and contribute to the objects and purposes of the IEP-SAC. Lets join hands with the Saudi Council of Engineers (SCE) , who has now more than 5300 Pakistani engineers registered with them. I would highly recommend to all those engineers whose iqama title is not an engineer to change their title as an Engineer and join both professional organizations i.e. IEP-SAC & SCE. This year 2013 – 2014 should be our membership year. The cooperation of IEP-SAC and SCE will further strengthen the already existing strong relationship between PAKISTAN and SAUDI ARABIA.

O

n behalf of the Council of The Institution of Engineers, Pakistan it gives me immense pleasure to Congratulate The Institution of Engineers, Pakistan (IEP) Saudi Arabia Centre on the occasion of holding Seminar on “Energy Security Interest of Pakistan” and on publishing “The JOURNAL 2013-2014” under the patronage of Pakistan Embassy/ Consulate. I am confident that this Seminar will give an opportunity to highlight the progress made in recent years for promoting and disseminating the knowledge in respect of the theme of this Seminar to the local and expatriate engineers working in the Kingdom of Saudi Arabia. The importance of natural resources in today’s competitive environment cannot be ignored. Resources are generally defined as stock of capital, labor, land, mineral wealth, the level of education, knowledge and technology. The proper and planned use of these resources for the mankind requires a proper environment conducive for the development of natural resources. We appreciate the efforts made by The Institution of Engineers Pakistan (IEP) Saudi Arabia Centre, KSA for their untiring efforts to bring together so many local and expatriate engineers working in KSA to share their ideas and expertise. An event of this magnitude is a substantial undertaking and the IEP will reap extensive benefits from your efforts. The sharing of knowledge and building professional ties among the professional engineers is vital to the advancement of the profession and the continued level of excellence in Engineering. We are proud that from its inception, IEP Saudi Arabia Centre has been working exceptionally good for the Engineers and Engineering Community in KSA. Specially through well reputed journal ”The Engineers”, they have been able to serve the engineering community in great way.

Message from Saudi Council of Engineers

Riyadh Cables Group of Companies E

ngineers play key role to increase productivity and the development of any country. As a result, the overall engineering employment is expected to grow by 10 percent per annum over the next decade. With the current financial crisis and expected recession, overall job opportunities in engineering discipline are still expected to be good, and indeed, prospects will be excellent in certain specialties. The trend for this future demand of engineers that will continue even during economic slowdowns will be on research engineers, high-tech engineers, electronics and aerospace engineers. Therefore, the engineering-discipline development through organizations such as SCE or IEP is an important issue, because the value of engineers depends not only on their knowledge of the latest technology, but also on their interaction, cooperation and networking under the umbrella of such NGOs. The role of such professional societies is important and vital to meet the needs of 21st century.

Quality First

Saudi Council of Engineers is a professional body that aims to promote the engineering profession and do whatever may be necessary to develop and upgrade its standards and practices. The main responsibilities of the Council are setting criteria and standards of practicing and developing this profession including licensure terms and conditions; prescribing necessary rules, regulations, and examinations for professional degrees; preparation and publication of studies and researches; organization of Engineering courses, conferences, seminars, workshops and symposiums related to the profession. Promoting engineering profession in the KSA is the main goal of the Council. The contributions by Pakistan engineers to the development of Saudi Arabia through the past decades are well recognized by SCE. Therefore, Pakistan – Saudi Arabian relationship is a special one, indeed at all levels. For example, another Memorandum of understanding (MOU) has been signed between SCE and IEP on February 3, 2013, addition to the one which was signed in year 2008, by which both parties wishes to develop an active relation through the development of professional services in the fields of engineering accreditation, continuous development training programs, engineering events, and exchange of expertise and knowhow between the two brotherly Islamic countries.

studies and was honoured with gold medal in the university being on the top of the graduate students list. He was awarded with a prestigious scholarship and able to further strengthen his excellence with completing M. S. (Mechanical Engineering) in 1975 from Washington State University, Pullman, USA. During his masters, Anwar was offered to continue his research for Ph. D. in Mechanical Engineering at Michigan Technological University (MTU), Houghton, MI, USA. He was awarded Ph. D. degree in 1978 with specialization in Industrial and Manufacturing Engineering. Immediately after completing his Ph. D. Dr, Anwar was appointed as Assistant Professor in the Mechanical engineering and Engineering mechanics department of the same university and enthusiastically started teaching and research in the field of his interest, i.e. Industrial and Manufacturing engineering. After a year in 1979, Dr. Anwar Khalil was offered to work as Assistant Professor at the department of Mechanical engineering at King Fahd University of Petroleum and Minerals (KFUPM), Dhahran Saudi Arabia. The love and respect of the holy land adds further attraction to this offer and compelled him and his family to move to the Kingdom of Saudi Arabia. In recognition of his hard work and

quenched fully in KFUPM and his enthusiasm for research forced him to join back the department of Mechanical engineering and Engineering mechanics at MTU, Houghton, Michigan USA in 1985 as Associate Professor. However, after a year, he was requested to join KFUPM again in 1986 in the same position, i.e. as Associate Professor. He joined KFUPM with the permission to work in parallel at MTU as well, where he worked as Adjunct Associate Professor from 1986 until 1995. Later on he was promoted to Adjunct Professor in 1995 at MTU and worked until 1999 at this position. Meanwhile he was promoted to the position of Professor at KFUPM in 1994 and still working at the same position. Professor Anwar has taught more than 30 courses for undergraduate and graduate classes at KFUPM and Michigan Technological University (MTU) and 17 short courses to industry.

Tsunamis-causes, effects, and preparedness

Tsunamis-causes, effects, and preparedness

TSUNAMIS-CAUSES, EFFECTS, AND PREPAREDNESS by Engr S M H Kirmani A tsunami is a wave train or a series of waves generated in the body of water by a sudden impulsive disturbance on the ocean floor that vertically displaces water column. Among the causes of this sudden motion are: earthquake underneath or near the ocean, a powerful volcanic eruption under the ocean bed, underwater landslides, impact of celestial objects, or nuclear explosions.

and brittle enough to break under stress and produce an earthquake. The lower mantle is warm to hot, its highest temperature occurs when mantle material is in contact with heat producing core. Instead of breaking, a semi molten flow occurs when subjected to force.

EARTH AND ITS INTERNAL STRUCTURE

The depth of the core is about 3000 to 3500 km. It comprises of two zones:

About two-third of the Earth is covered by the water of four oceans: Pacific, Atlantic, Indian, and Arctic oceans. The Pacific Ocean is the world’s largest ocean covering6 more than one-third of the Earth’s surface (165.2 × 10 2 km ) and contains more than half of the Earth’s water. Average depth of the Pacific is 4270 m, the deepest known point being 11 000 m deep.

Divergent Plate Boundary—Oceanic

Convergent Plate Boundary-Oceanic

When a divergent plate boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere producing a mid-ocean ridge, which on further stretching results in a deep fissure. When fissure opens, pressure is reduced on the superheated material below. It responds by melting and new magma flows into fissure, solidifies, and forms new crust. Earthquake activity may be resulted. Figure 2 explains the process.

It is the case when a convergent boundary occurs between two oceanic plates, the older and denser plate will subduct beneath the other. The subducting plate is heated as it is forced deeper into the mantle and at a depth of about 150 km, plate begins to melt. Magma chambers are produced as in previous case, which reach the surface to form a volcanic eruption cone. A zone of progressively deeper earthquake, an oceanic trench and chain of volcanic Island is resulted (Figure 5).

Core

i) The outer core, about 2300 km deep, is liquid because the temperature in the upper core is estimated to be in excess of 4000 °C, which is sufficient to melt ironnickel alloy. ii) The inner core, about 1230 km deep is solid even though its temperature is higher than the outer core. Here, tremendous pressure, produced by the weight of the overlying rock is strong enough to crowd the atoms tightly together thereby preventing the liquid state.

Figure 5: Convergent plate boundary (Oceanic)

Convergent Plate—Continental

Figure 2: Divergent plate boundary (Oceanic)

Divergent Plate Boundary-Continental In this case, the continental plate is arched upwards by the rising convection current, pulled thin at the ridge by extensional forces, and fractured into a rift-shaped structure. Normal faults develop on both sides of rift and central block slide down allowing ocean water to flow in. This rift can then grow deeper and wider and a new ocean basin could be produced (Figure 3). Red sea is such an example.

In this type of convergence between two thick continental plates, a powerful collision occurs. No subduction takes place, but the intense compression can cause extensive folding and faulting hundred of miles into the plate interior. Himalaya mountain range is the best active example of this type of plate boundary.

Plate tectonics: Lithosphere and Asthenosphere

Figure 1: Earth’s internal structure: crust: 5-50 km, mantle: 2900-3000 km, outer core: 2200 km, inner core: 1260 km [1-3]

Crust Earth’s crust is composed of: i) Thin oceanic crust that underlies the ocean basin and varies from 5 to 7 km and mainly consists of Basalt. ii) Thick continental crust that underlies continents and varies from 30 to 50 km and consist of Granite.

Mantle The overall depth or thickness of Mantle layer is about 2900 to 3000 km. It consists of two zones, the upper mantle, and the lower mantle. Rock in the upper mantle is cool 40



Plate tectonic theory holds that “Lithosphere” which consist of the crust and part of the upper solid mantle is divided into about seven major plates and perhaps twelve smaller plates, about 130 km thick, resting upon a shaft of semi-molten mantle layer called Asthenosphere. The continents, which are 8 to 100 km thick are embedded in some of the plates and hence move as the plate moves about on the earth’s surface. These movements are very slow, only 2 to 3 cm per year. Tectonic plates interact along their boundaries or edges referred to as fault lines or faults. Sometimes, the forces along the faults can build-up over a long period of time so that when structural changes in the crust occur and rock finally breaks, an earthquake occurs. When powerful, rapid faulting occurs underneath or near the ocean, a large earthquake is produced and possibly, a Tsunami. TYPE OF PLATE BOUNDAREIS

Figure 6: Convergent plate boundary (Continental)

Overall Tectonic Setting of Indian Tectonic Plate Figure 3: Divergent plate boundary (Continental).

Convergent Plate Boundary—Oceanic and Continental In this case, the thinner and denser oceanic plate is overridden by the thicker plate. The oceanic plate is forced down into the mantle at about 160 km in a process known as subduction. Magma chambers rise upward through fissures in overriding plate causing volcanic eruption. See Figure 4.

Behavior of Tectonic plate boundaries depends on the direction of their movement. Three major types of plate boundaries are noted [4]: i) Divergent Plate Boundary (oceanic and continental). ii) Convergent Plate Boundary (oceanic/continental, oceanic/oceanic, and continental/continental). Figure 4: Convergent plate boundary (Oceanic and Con-tinental)

iii) Transform Plate Boundary.

IEP-SAC Journal 2012-13

Best example of the convergent plate boundary—continental is the migration of the Indian tectonic plate and its collision with Eurasian tectonic plate which has developed a diffuse zone of deformation and seismicity in the entire South Asian region (Figure 7). Major thrust or reverse type of faulting has caused upward displacement of the Indian plate and the formation of Himalayan Mountain is resulted. Total migration of the Indian Tectonic plate at the rate of 1 cm/year in 70 million years has been 700 km.

Transfer Plate Boundaries Places where plates slide past each other are called transform boundaries. In this case, motion along the fault is sideways and not vertical. Transform boundaries are marked in some places by linear valleys, while in other places they are marked by features like stream beds. The most famous transform boundary in the world is San Andreas Fault zone of Western North America (Figure 8). The sliding motion causes Earthquakes. The strongest earthquake along the San Andreas Fault hit San Francisco in 1906.

Tsunamis-causes, effects, and preparedness

Tsunamis-causes, effects, and preparedness Tsunami Races Away from the Epicenter The moving wave starts traveling out from where the earthquake has occurred (epicenter). Some of the water travels out and across the ocean basin, and, at the same time, water rushes landward to flood the recently lowered shoreline (Figure 12).

height near the coast, typically 10 to 25 m, resulting in the most devastating waves.

Figure 9: Earthquake in the subduction zone Figure 13: Shoaling effect

Accumulated Seismic Energy Figure 8: San Francisco fault zone

GENERATION OF TSUNAMIS The main cause of the Tsunami generation is the earthquake underneath the ocean bed or near the ocean. After the study of the plate boundary conditions, we can easily understand the various phases before a Tsunami is generated [5-7]:

How Does an Underwater Volcano Causes a Tsunami?

As a stuck plate continues to descend into the mantle, the motion causes a slow distortion of the overriding plate. The result is an accumulation of energy similar to the energy stored in a compressed spring. Energy can accumulate in the overriding plate over a long period of time, decades, or even centuries. Figure 12: Tsunami races away from the epicenter

Tsunami Travels Rapidly Across the Ocean Basin

Subduction Zone Most tsunamis are caused by earthquake generated in a subduction zone, an area where an oceanic plate is being forced down into the mantle by plate tectonic forces.

Figure 10: Accumulated seismic energy

Earthquake Causes Tsunami Energy accumulates in the overriding plates until it exceeds the frictional forces between the two stuck plates. When this happens, the overriding plate snaps back into an unrestrained position. This sudden motion is the cause of the tsunami, because it gives an enormous shove to the overlying water. At the same time, inland areas of the overriding plate are suddenly lowered.

Tsunami behaves as shallow-water waves due to its long wavelength which could be in excess of 100 km. A wave becomes a shallow-water wave when the ratio between the water depth and its wavelength gets very small (H/S). Shallow water waves move at a speed of n(gH), where g is the acceleration due to gravity and H is the water depth. In the Pacific Ocean, for example, where typical water depth is about 4000 to 5000 meters, the speed of Tsunami waves would be 796.9 km/h, the speed of a Jetliner!

The friction between the subducting plate and the overriding plate is enormous. This friction prevents a slow and steady rate of subduction and instead the two plates get “Stuck” (Figure 9).

Figure 11: Earthquake causing the tsunami 42



IEP-SAC Journal 2013-14



www.iep-sa.org

The process of Tsunami generation in such cases is the result of an explosive interaction between water and magma, which produces fine, grained tephra with the emission of magmatic gases and steam. These eruptions can create catastrophic tsunami waves. For example, after the eruption of Krakatau volcano, in Indonesia, in 1883, the wave height upon reaching the sea shore was 45 meters. There are at least nine different mechanisms by which volcanoes produce tsunamis. i) Volcanic earthquake. ii) Eruption of undersea volcanoes. iii) Travel of pyroclastic flow into the Sea (fast moving current of hot gases and rock, “Tephra”).

Because the rate at which a wave losses its energy is related to its wave length, tsunamis not only propagate at high speed, they can also travel great trans-ocean distances with limited energy losses. A tsunami produced by an earthquake along the coast of Chile in 1960 traveled across the Pacific Ocean reaching Hawaii (10 842 km) in about 15 hours and Japan’s cost of Osaka (17 595 km) in less than 24 hours. The height of waves in deep Ocean is hardly a foot high thus unnoticed by sailors.

How Does a Tsunami Wave Change as it Reaches the Coast? Figure 7: Formation of Himalayan mountain range

A submarine or offshore volcanic eruption can produce high magnitude lifts on sea floor, which pushes large water columns upwards to generate Tsunamis. They are usually found near the areas of tectonic plate movement.

When a tsunami travels into the shallow water near the coast, the character of wavelength, speed and uplift changes. The speed of waves in 500 m deep ocean drops to about 250 km/h. As the water depth decreases, the tsunami energy flux, which is depended on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami speed diminishes while it travels into shallow water, its height grows. As the tsunami attacks the coastline, the wave energy is compressed into much shorter distance. Because of this shoaling effect, a tsunami, imperceptible at sea may grow several meters in

iv) Caldera collapse (a large crater formed by volcanic explosions or by collapse of a volcanic cone). v) Debris avalanches and landslides. vi) Large Lahars (a type of mud flow or debris flow composed of slurry of Tephra and water) entering the sea. vii) Phyreatomagmatic explosion (an explosive watermagma reaction). viii) Coupling between water and turbulent air waves traveling from an explosive eruption. ix) Collapse of Lava benches during effusive lava eruption. Most devastating undersea volcanoes have been [7-8]: i) Coast of Tonga located about 30 km from Falcon Island in Pacific Ocean. This volcano erupted on March 18, 2009 as a result of melting of two tectonic plates. ii) Sumatra, Western Indonesia. It is the largest island in Indonesia and world’s sixth largest in the world. Sumatra’s volcanism is caused by North-eastward subduction of the oceanic Indian-Australian plate. A

Tsunamis-causes, effects, and preparedness Richter Scale 9.3 earthquake on December 26, 2004 generated catastrophic tsunami that effected and rocked the Asia. iii) Eldfill volcano, located over 200 meters high on Heimaey Island, Iceland. First ever volcanic eruption took place in January 1973 in the town of Vestmannaeyjer.

Submarine Landslides Submarine landslides can also cause Tsunamis. Submarine landslides can be caused by: (1) earthquake, (2) Eruption of underwater volcanoes, and (3) Debris avalanches and falling of sediments and rock. Tsunamis caused by these mechanisms generally dissipate quickly and rarely effect coastlines distant from the source unlike the ocean-wide tsunamis caused by earthquakes. In 1958, a landslide triggered by an earthquake of magnitude of 8.3 on the Richter Scale at the head of Lituya Bay, Alaska, produced a water wave estimated at 50-150 m which ran up the valley walls to a height of 524 m. It is the largest tsunami ever recorded in the modern times and has been given the special name of mega tsunami.

TSUNAMI GENERATED BY METEORITES Meteorite impacts into ocean displaces huge quantity of water sending out tsunamis (Figure 14). Geomorphologists at the University of Wollongong in New South Wales have cataloged a mass of evidence around the Australian coast for these tsunamis. A new Archeological study suggests that a meteorite impact off Long Island 2,300 years ago may have set off a huge tsunami that flooded the New York City region.

Tsunamis-causes, effects, and preparedness

undating or flooding hundred of meters inland, pass the typical high water level. The fast moving water associated with the inundating tsunami can crush homes and other coastal structure. Tsunamis are among the most terrifying natural hazards known to man and have been responsible for tremendous loss of life and property throughout history. The direct effects are: loss of life; damage to, or destruction of buildings, boats, critical facilities like nuclear installation and other coastal infrastructure; loss of coastlines; and excessive scattered debris. The less direct effects are: contamination of coastal soils, diminished domestic water supply due to contamination of shallow wells and aquifers, disease outbreak, interruption of business and economic process, and disruption of educational and social services.

TSUNAMIS FORECASTING, PREPAREDNESS, AND WARNING While tsunamis cannot be prevented, or their destructive effects entirely avoided, actions can be taken to mitigate the risk of this hazard, thereby reducing the impacts on life, physical structure, and livelihood. To forecast tsunamis and determine terminal run-up and destructiveness, one must be able to evaluate the parameters of the tsunami source mechanism in real time. Tsunami source mechanism analysis is difficult given the time constrains of a warning situation. Forecasting the run-up and potential destructiveness of a tsunami at a distant shore will depend greatly on determining the seismic parameters of the source location, such as: the magnitude of the earthquake, its depth, its orientation, the length of the fault line, the size of the crustal displacement, and the depth of water. Finally, terminal height, run-up of the tsunami at a point of impact will depend upon the energy focusing effect, the travel path of the waves, the coastal configuration, and the offshore bathymetry, etc.

Mitigation Strategies Tsunami risks can be mitigated through many actions that minimize the effects of coastal hazards, such as [910]:

Land use management to minimize development in areas of potential tsunami inundation.



Preservation of natural barriers or dunes along coastline.



Establishment of design standards, building codes, or guidelines for construction of buildings within coastal areas. Buildings should be placed 2-3 m above the high tide level.

dily built structures. The international tsunami survey team (ITST), recommends the following land use considerations: •

Residents should not be relocated in areas fronted by water and backed by rivers or lagoons, and



Schools, buildings for worship like mosques and other critical facilities should never be located closer than 400 meters from the coastline, and preferable 800m in at-risk areas.

CONCLUSIONS The phenomenon, we call a tsunami (SOO-NAH-MEE) meaning “harbor wave” is a series of waves of extremely long wave length and long period in a body of ocean water by an impulsive disturbance that displaces water. Tsunamis are primarily associated with earthquakes in oceanic and coastal regions, landslides, volcanic eruptions, nuclear explosions, and even impacts of object from outer space (such as meteorites and asteroids) can also generate tsunamis. Effect of tsunamis in many cases is loss of life and destruction of buildings, critical facilities and coastal infrastructure. Actions can be taken to mitigate the risk of this hazard. This needs to adopt mitigation strategies, which include: •

Abstract

se of solar energy is not new to mankind. It is the very reason that life exists on Earth. In the wake of global energy shortage, solar energy is being considered as the best alternative among other available sources. Researchers have developed different methods to convert sunlight and heat into electricity. Semiconductor industry has played a major role in uplifting this technology and deploying it in areas where conventional electricity is not available; the space program introduced the use of highly efficient multi-junction solar cells. They are now being used in conjunction with optical concentrators and have given rise to what is now known as the “concentrated photovoltaics”. This paper gives a brief overview of different concepts in CPV technology and highlights its key feature INTRODUCTION Solar cells are electronic devices that convert sunlight directly into electricity. They work on the principle of photoelectric effect. Like other devices, solar cells have a theoretical efficiency limit which was given by Shockley and Queisser in 1961 [1] as 30 % for energy gap of 1.5 eV. This efficiency limit has never been achieved by single junction solar cells. According to latest research, the highest efficiency achieved by single junction solar cells is 28.3 % [2]. The Shockley-Queisser limit can be defied by using tandem cells also known as multi-junction solar cells with a technology known as Concentrated Photovoltaics (CPV). The theoretical maximum efficiency of infinite tandem cells is 87 % under highly concentrated sunlight. CPV is a promising technology for future solar power projects and has a wide potential for development. At present, the highest achieved efficiency for triple junction solar cell is 44 % [3]. Limitations of Single Junction Solar Cells and NonConcentrating Systems Single Junction solar cells are limited to a theoretical maximum efficiency of 30 % due mainly to the fact that a single junction solar cell can absorb only certain wavelengths of lights. As an example, a single junction silicon solar cell absorbs only photons having energies greater than the band-gap energy of Silicon; the remaining photons, which mainly consist of infrared light, are lost as heat. Figure 1 shows the AM 1.5 spectrum with three highlighted regions. The UV region is small; the visible region is dominated by green light (550 nm) whereas the region from 750 nm to 1000 nm is the infrared region. 46



Infrared constitutes almost half of the radiation coming from the sun. This loss in a single junction solar cell is considerable to cause a heavy drop in efficiency. Figure 1: Global and Direct AM 1.5 radiation spectrum (www.newport.com)

The second factor affecting the efficiency of solar cells is the blackbody radiation loss [1]. This is because a practical solar cell does not operate at absolute zero temperature hence whatever energy it absorbs from sunlight, some of it is radiated as blackbody radiation. The Third factor for efficiency drop is recombination phenomenon. It accounts for almost 10 % of losses in a solar cell. When light falls on a solar cell, it generates an electron hole pair. In recombination the electrons combine with holes and release energy thereby lose that energy they gained from light without doing any useful work. This process is undesirable in case of solar cells. Among the losses discussed above the most significant loss is due to the limited wavelength capturing capability. This loss can be compensated by increasing using what is called a tandem or multi-junction solar cell.] MULTI-JUNCTION SOLAR CELLS (MJSC) A multi-junction solar cell is a special type of solar cell consisting of different layers each capable of capturing a certain wavelength from the sunlight. This can be achieved in two different ways: (1) stacking the layers, and (2) laying the layers parallel to each other. Both of these arrangements are shown in Figure 2. In part (a) of the Figure, a prism splits the light into its components and each component illuminates the respective layer. The second arrangement, part (b), is much simpler as it does not involve a prism. Light hits the first layer; some of it is transmitted to the next layer and so on. It must be noted here that each layer should be transparent so that it allows the layers underneath to get illuminated.

Figure 2: Two different arrangements for multi junction solar cells

The most common of the multi-junction solar cells is a triple junction solar cell shown in Figure 3. It consists of a top layer of Indium Gallium Phosphide (bandgap 1.86 eV), middle layer of Indium Gallium Arsenide (band-gap 1.4 eV) and the bottom layer of Germanium (band-gap 0.65 eV). The corresponding spectrum of light is shown in part (b) of the Figure. The cell is capable of absorbing the entire visible spectrum as well as a part of infrared spectrum. The current maximum efficiency of a triple junction solar cell as of December 2012 report by National Renewable Energy Laboratory (NREL), is 44 % [3]. The problem with these cells is that they are very expensive owing to their much complex design as compared with single junction cells. Although they are highly efficient yet they are not economical to be used like conventional single junction cells. A simple and effective solution is to use a concentrator.

CONCENTRATED PHOTOTOVOLTAIC SYSTEMS Concentrated photovoltaic is one of the possible approaches to reduce the cost of photovoltaic power. The idea behind the technology is very simple. Solar cell produces power by capturing photons. More photons mean more power. There are two options to capture more photons. Either increase the area of solar cell or increase the number of photons [5]. The first method is expensive. As discussed in earlier sections, a single junction solar cell, although cheap, can be used on large areas but it is not a solution as there are some locations where land is expensive. As for multijunction cells, they are even expensive. The second method is to increase the number of photons. This can be accomplished by using what is called a concentrator. A concentrator is an optical device which captures large quantities of light and focuses it onto a much smaller area. The concentrator enables to increase the energy production capability of solar cell by increasing the quantity of light falling on it.

Triple Junction Solar Cells Triple junction solar cells were initially developed for the space program, where the power to weight ratio is a critical issue. The radiation spectrum in the space is known as AM0 spectrum. In order to capture as much sunlight as possible with the smallest cell size, tandem solar cells capture different energy wavelengths. The complete package has the ability to catch a much wider radiation spectrum than a single junction solar cell. Figure 4 shows the historical development of solar cells as reported by NREL [4]. This chart shows that the development of multijunction solar cells started during the 80’s and that of triple junction solar cells with concentrator started in 2000. However, the technology of CPV is not new; historic CPV systems were introduced as long ago as during the 1970s and continued in 1980s when the drive for solar energy was high following the 1973 oil crisis.

Figure 4: Efficiency Record Chart maintained by NREL [4]

Concentrator Design Some of the concentrator design features are explained below. Aperture Area Aperture area is the area of the face which directly faces the sun and collects sunlight. The more the aperture area, the more is the captured light. Aperture area can also be assumed as the inlet area of the concentrator. Exit Area The area of the focal point is called the exit area. Geometrical Concentration Ratio Concentration ratio is the ratio of aperture area and exit area [6]:

It can also be defined as the ratio of area of the collector system to the area of the solar cell.

Concentrated Photovoltaics

Concentrated Photovoltaics

Acceptance Angle Acceptance angle is the highest incident angle when a ray of light strikes the concentrator and reflected to the focal point. Any ray coming at an angle greater than acceptance angle will not be focused.

Fresnel Lens

Collector Efficiency

Focal Length

Collector efficiency is the ratio of irradiance received by the solar cell to the irradiance received by the aperture. Types of Concentrators Concentrators can be classified in two ways. One method is by the optical means that the concentrator uses to concentrate sunlight while the other way is by the tracking method. Classification Based on Types of Optics There are two main optical technologies in use today. One is reflective optics while the other is refractive. Both have their advantages and disadvantages. This section will discuss two main types of concentrators being used these days in CPV: the Fresnel lens concentrator and the parabolic dish concentrator. Fresnel lens Concentrator A Fresnel lens is a special type of lens which can be thought of as a plano-convex lens that has been collapsed at a number of locations into a thinner profile. Figure 5 shows a Fresnel lens with an equivalent plano convex lens. The advantage of using a Fresnel lens is that it is very light and can be manufactured from acrylic resin (PMMAPolymethyl methacrylate) as compared with plano-convex lens which is heavy and is made from glass. A Fresnel lens can concentrate sunlight onto its focal point thus acts as a concentrator (Figure 6). Fresnel lens concentrators are one of the most widely used concentrator technologies. One of the earliest CPV plants was installed in Riyadh, Saudi Arabia. The solar modules used the Fresnel lens concentrator to focus sunlight onto a circular cell of 5 cm diameter and had a concentration ratio of 40x. Figure 7 shows the field view of Riyadh Solar Village.

Figure 6: A Fresnel Lens Concentrator

Parabolic Dish Concentrator A parabolic dish concentrator is a reflective dish with a parabolic profile. The light falling on the dish is concentrated onto the focal point of the parabola. Figure 8 shows a parabolic dish concentrator. The solar cell is placed on the receiver. Large parabolic dish concentrators are used in solar thermal applications yet small parabolic mirrors are also used with photovoltaic cells these days. Figure 9 shows how a parabolic mirror concentrator is used with a multijunction solar cell. Figure 10 is a CPV module made from parabolic mirror concentrators.

Figure 7: Riyadh Solar Village was the largest Fresnel lens based CPV plant in the world till 1989

Figure 10: An array of parabolic mirror concentrators

Secondary Optics One of the good design features of a concentrating system is its higher acceptance angle. The acceptance angle of any concentrator is inversely proportional to the concentration ratio. The higher the concentration ratio, the lower is the acceptance angle. This is because a slight change in the incidence angle will have a major impact on the position of focal point which can become disastrous as the temperature at focal point is high enough that it can burn other components inside the module.

CPV systems require direct radiation for their operation; hence continuous active tracking systems are required. Active tracking enables a concentrator to continuously collect direct solar radiation throughout the day time as long as sun is available. The tracker follows the sun with very high precision. A good tracker keeps direct beam solar radiation always at right angle to the concentrator surface. The tracking accuracy depends upon the acceptance angle of the concentrator. If the acceptance angle is large, less tracking accuracy is required hence cost is reduced and vice versa. The tracking system used in CPV applications has two main components (Figure 13). i. Azimuth Drive to track the sun in east-west direction ii. Elevation Drive to track the sun in north-south direction

For increasing the acceptance angle, a special type of optical device is used, called the Secondary Optical Element (SOE). The purpose of SOE is to collect concentrated light and direct it to the solar cell. SOEs come in different shapes and sizes. Some of them are shown in Figure 11 and Figure 12 respectively. Figure 13: Front and Back Side of a Fresnel lens CPV Tracker showing Azimuth and Elevation Axis along with other parts

Figure 14 shows how tracking affects the total energy collected by the panel in one day. The area under each curve shows the energy collected. The highest energy is collected when dual axis tracking is used. For a fixed flat plate, the energy collected is minimum.

Concentrated Photovoltaics Classification Based on the Concentration Ratio Apart from the type of optics, CPV systems are also classified on the basis of their concentration ratio. These classes start from very low concentration to very high concentration. The specified values of concentration ratio are not hard and fast but vary from manufacturer to manufacturer. These classes are: Low Concentration PV (LCPV) The concentration in LCPV system varies from 2 to 100 suns. Such systems typically use single junction silicon solar cells for economic reasons [7]. Medium Concentration PV The concentration range is between 100 to 300 suns. The CPV system at these levels of concentration requires a two axis tracking system [7] as shown earlier under the tracking system. High Concentration PV (HCPV) Concentration levels above 300 suns known as HCPV systems. They operate best with multi-junction solar cells, require a cooling system either passive or active and a dual axis tracking system with very high tracking accuracy [7]. The l limit of concentration for HCPV is taken as 1000 suns [8]. Ultra High Concentration PV (UHCPV) CPV systems are sometimes also classified as UHCPV systems which have concentration levels above 1000 suns. These systems are still under research and face problem such as extremely high tracking accuracy and active cooling systems. One such project is underway in Riyadh, Saudi Arabia, under the auspices of King Abdulaziz City for Science and Technology (KACST).

optics e.g. mirrors. The solar cells used for CPV are high efficiency multi junction solar cells. These cells have the capability to capture a wide spectrum of sunlight. High precision tracking is required for CPV systems. The tracking accuracy can be decreased by using secondary optics. REFERENCES 1.

Potential Of Cpv Vs Other Technologies CPV is currently the fastest growing segment of the PV industry. Installations from CPV are projected to hit the 1GW mark in the next 5 years, from only tens of megawatts in 2011. The rise in popularity of CPV among project developers, Independent Power Producers (IPPs), utilities, and investors is a reflection of confidence in the technology and its roadmap to achieve cost reduction towards becoming the technology with the lowest Levelized Cost Of Electricity (LCOE). This is despite due to the continued lowering prices of silicon panels and CdTe thin film panels.

Automobile Power Liftgate

A New Design For for Automobile Power Liftgate Motor by Qanit Al-Syed, Yihong Lan, Alejandro Martinez, Sudarshan Sivaramakrishnan, Joe Yancey Electrical Engineering Department, University of Michigan at Ann Arbor

Abstract

T

his paper presents the authors’ design proposal for the Power Liftgate Motor System in response to the manufacturer, B2P’s, request for a better design that would reduce the cost and increase the profitability. The final proposal is two-fold. The first part of the new design is the usage of a planetary gear system as opposed to the standard gear system of the original model. It is shown that this would make the gears work in a linear fashion (that is, not shifting the axis of rotation from input to output), which would result in a more compact model and reduce weight and material costs for the gear casing. The second part of the new design deals with changing the material of which the mounting plate is composed from low-carbon steel to an ABS polymer. The ABS polymer mounting plate would be thicker and have a slightly greater surface area than the original plate. It is shown that the proposed design for the mounting plate would translate to a lighter weight and a decrease in production costs. The paper utilizes the concept of Net Present Value (NPV) to prove that the design proposal is more profitable than the original design. Lastly, the paper analyzes the failure modes associated with the new design. The three major failure modes, namely, breaking/deformation of the mounting plate, lower tolerance range for piece-to-piece variation, and increased maintenance costs—are found to be insignificant in the new design and as such are outweighed by the the benefits. INTRODUCTION

when the path is obstructed. The Controller is wirelessly linked to the user’s keys such that when he/she presses a button, it would signal the controller to turn on the Power Liftgate Motor. The manufacturer wants to reduce the costs of its Power Liftgate Motor. Low Material costs and Low Manufacturing costs are important factors and so are given weights of 9 each in the design matrix (Table 1). Compact design (importance rating of 22) has a weight of 6 and low weight (importance rating of 28) has a weight of 4 because they do not affect the customer in the end but are important as they contribute to ease of installation and space taken. Reliability (importance rating of 91) and safety (FMVSS 118) [2] are most important to the customer and so they both are given a weight of 10. Durability (importance rating of 41) is important for the customer as well but not as important as low costs or safety; therefore it is given a weight of 7. Minimal piece-to-piece variation only affects the manufacturing process (importance rating of 31). However since the parts have a significant tolerance range, it is given a weight of 5. Customer needs are also very important and so it has a weight of 8. Using these criteria, we came up with the following two solutions. Gear System The current gear system is a standard gear train. It extends in an “L” shape and so adds to the cost of an expensive Zinc gear housing. The new solution is to change the standard gear system to a

The basic power liftgate system of a motor vehicle includes a liftgate door hinged to the vehicle body, obstruction detectors, actuators, gas struts and a motor that controls the opening and closing of the gate. This vehicle liftgate power operating system should be able to lift the gate from a closed position to a fully opened position as well as from an open position to a fully closed position. It is used in a range of vehicles from trucks to minivans. The power liftgate is usually the back door or the cargo door.

Mounting Plate The motor used by FORD™ in their power liftgate system has a large metallic mounting plate attached to the bottom. Its basic purpose is in the production line to allow for easy mounting of the motor onto the rear of the vehicle. However since it is made out of a metallic material such as plain low-carbon steel and with galvanic coating it adds to the weight and cost of the system. The idea is to replace this metallic plate with a plastic plate that could possibly reduce both the weight and the cost of developing the system.

In our application of the liftgate motor, we need two of these gear systems. The output from the first would feed through the Hall Effect Sensor, and into the center gear of the next system. Each system reduces the angular velocity to 1/5th its input. The total angular velocity reduction is 1/25. This change in gear system will result in increased durability of the system. From the P-Diagram (Figure 2), we can see that the increase in durability will lead to the power liftgate motor being less severely affected by the noise factor durability and fatigue life. This results in lesser undesired errors so the power liftgate can open in the target range of 7± 0.5 seconds and close within 8 ± 0.5 seconds.

SOLUTION DETAILS Gear System

Problem and Solutions

The Power Liftgate Motor is a key component of the Power Liftgate system, which is used to operate the “backdoor electric open/close system” [1]. The motor system consists of a DC Motor, a mounting plate, a PLG Module circuit that is used to regulate the motors operation, and a small speaker used to alert people when the system is in operation. The PLG Module is linked with the motion sensors in order to stop operation of the Power Liftgate

planetary gear system. This would reduce the casing material needed as well make the motor more efficient.

Planetary Gears Figure 1 shows the four basic components of a planetary gear system, which are [3]: 1.

Sun Gear: The central gear

2. Planet Gears: of the same size, meshed with the sun gear 3. Planet Connector: Holds the three peripheral planet gears.

Figure 2: p-Diagram

4. Annulus: An outer ring with inward-facing teeth that meshes with the planet gears.

Design

In many planetary gearing systems, one of these three basic components is held stationary; of the two remaining components, one is an input, providing power to the system, while the other component is an output, receiving power from the system. The ratio of input rotation to output rotation is dependent upon the number of teeth in each gear, and upon which component is held stationary.

1. The output from the DC motor will be fed directly into the first gear system. 2. This gear will engage the three outer planetary gears 3. The planet gears would spin in the annulus, opposite the direction of the center gear. 4. The sun gear for the next system would spin with the same angular velocity as the first gear connector 5. This engages the second set of planetary gears. 6. The planet gears would spin in the annulus, opposite the direction of the center gear. 7. This planet gear connector will spin in the same direction as the input gear, but at 1/25 the speed. 8. The liftgate actuator connects to this connector and opens the liftgate. Mounting Plate

In the new application of the planetary gear system, the annulus would be held stationary, the sun gear is the input, and the planet connector is the output. The casing of the system would be the annulus, with teeth on the inside. This optimizes the space used in the casing. The planetary gear arrangement also creates increased rotational stiffness, and greater stability, due to the balance of the system.

The gear design is as follows:

Figure 3 shows the shape of the new plastic mounting plate. It is projected to be thicker in width and have a greater surface area. The 3 screw points shown on the figure are the points where the motor is mounted on the plate. The other points are used to fix the motor onto the mounting wall. Table 1: Design Evaluation Matrix

be $0.209 (0.115 × 1.81). This shows that replacing the current plate with a plastic plate would reduce costs by $0.606 per motor.

Cost Analysis Planetary Gear System The original gear housing is made out of a Zinc Alloy and has a weight of 2.5 lb. Figure 4a shows the relative weighs of the casing components. According to Anchorage Daily news [4], this alloy of Zinc costs $1.068/lb. Therefore the current casing costs about $2.67. Figure 4b shows the shape and the projected weight of the new gear housing. This new design reduces the casing weight by 20 %. As a result, the new projected cost is around $2.13 for the casing. This saves $0.54 in casing costs. The new design also reduces the number of fasteners or

The total reduction in costs per motor would be: 0.39 + 0.64 = $1.03. Assuming 300,000 cars equipped with this system are produced every year. This would reduce costs of production by $309,000.

Stress Analysis for plate The plate is mounted vertically on the side as shown in Figure 5. The arrow shows the bending effect of the load on the plate. There is a bending stress (σb) and a sheer stress (t) on the plate. The bending stress is on the overall plate as shown in Figure 5 while the sheer stress is at the three mounting screws that the motor sits on as shown in Figure 8.

moving.

Figure 8: New Gear Casing

Stress According to MatWeb Material Property Data [8], low carbon steel has a yield tensile strength of 180 to 240 MPa while ABS plastic has a yield tensile strength of 28 to 58 MPa. Therefore, even though the strength of ABS plastic is about 5 times less than that of low carbon steel, it is still a suitable material for the plate. This is because the stress exerted by the motor and the movement of the car on the plate is much smaller than both the yield strengths.

ECONOMIC FEASIBLITY The acceleration of the car is the same as the acceleration Figure 7: Mounted Motor

of the motor. According to Newton’s second law of motion, this acceleration results in a 12 N force on the motor which introduces another bending stress (σb2). It was assumed that a regular car can go through a maximum deceleration/ acceleration of 4 m/s when full brakes are applied at a top speed of 100 mph.

screws from six to three. Each fastener costs $0.05. As a result, this further reduces the cost by $0.15. However the new planetary gear system is more complicated and harder to assemble. We have estimated that it would increase the costs by $0.30. Tthe total reduction in costs due to the new planetary gear system is thus: 0.54 + 0.15−0.30=$0.39 5.

The radius of the mounting screws is 0.0125 m. Figure 8 shows the motor mounting points. Therefore, the contact surface area of each screw is: pr2 = 4.91 ×10−4. The Shear stress is:

Mounting Plate The current metal plate weighs about 2.5 lb. The price for flat steel per ton in the US is around $719 [5]. Therefore, the low carbon steel for the mounting plate costs $0.815 for 2.5 lb of flat steel. The best plastic that is suited for the mounting plate is Impact Grade, Acrylonitrile Butadiene Styrene (ABS). The density of this material is around 1.10 g/cc [6]. Assuming that the surface area of the plate is 374 cm2 (22 cm × 17 cm) and the thickness of the plastic plate is 2 cm, the total mass of plastic would come out to be 1.81 lb. The ABS polymer price in the US is $0.115/lb [7]. Therefore, the material cost for the plastic plate would 54

Our proposed design would reduce the cost of production by about $1.00 for each motor. The original design for the mounting plate is made of steel and weighs 2.5 lb, meaning that it costs $0.815 in materials at a price of $0.326/lb. Our mounting plate would be made of ABS plastic. Even though it will be thicker, it would still be lighter, weighing about 1.81 lb and costing $0.209 in materials (at a price of $0.115/lb). The difference in material costs for the plate is $0.606. Since we will change the gear system, it is necessary to change the casings. This introduces an initial expense for a new die, projected to be about $200,000. Subsequently, however, material costs and production will be cheaper, since the new design uses less material. The original zinc casing weighs 2.5 lb and costs $2.670 in materials at a price of $1.068/lb. The proposed design would weigh 2.0 lb and cost $2.136 in materials at the same price of zinc. The difference in material costs for the casing is $0.540. Then, there is also a decrease in manufacturing costs for putting the casings together, since our proposed design will reduce the amount of casings from 3 to 2 hence there will be 3 fasteners less and at a price of $0.05 per fastener, assembly costs will be reduced by $0.15. However, since the planetary gear system requires more assembly time we estimate this cost will go up by $0.30 per motor, we maintain that the amount of material used for gears will be the same, so material costs for gears will remain the same. Adding these figures up, we come up with a total savings of $0.996 per motor. Assuming that 300,000 motors are produced per year, this would lead to a savings of $298,800 per year, with an initial cost of about $200,000. To determine if the new design is actually profitable, we calculated the Net Present Value (NPV) of money that

Solving this equation for the interest rate, we found i = 147.8 %. Hence, for NPVoutflow original < NPVoutflow new, the interest rate must be greater than 147.8 %. Such an interest rate is unheard of in the general market, thereby rendering the new design more profitable than the old design over a five year period.

FAILURE MODES AND DRAWBACKS Despite the various advantages offered by the new design over the old one, there are also certain constraints that the new design scored lower on in the design matrix. This represents a possibility of new failure modes and drawbacks arising from adopting the new design. Hence, we will be evaluating the three constraints that the new design scored lower than the old design on the design 56

Mounting Plate Deforms As the maximum air service temperature for ABS plastic is 80 to 90 °C, there will be a chance of the plastic plate deforming when the temperature of the PLG motor rises to levels above 90 °C. However, Hi-Lex, one of the manufacturers of the motor, specifies the operating temperature of the PLG to be a maximum of 80 °C. This factor is represented by a low occurrence value of 1 in the simplified DFMEA shown in Table 2. Together with a detection value of 4 and a severity value of 5, it only brings the RPN of this failure mode to a relatively low value of 20. Hence, we can conclude that this failure mode does not pose a big problem.

CONCLUSION Our proposal consists of two parts: to change the gear system from a standard gear train to a planetary gear train and to replace the low-carbon steel mounting plate with an ABS polymer mounting plate. Based on cost analysis, stress analysis, and design failure mode and effects analysis, we find that our new design is more profitable and cost-effective than the original design as well as that our new design’s benefits outweigh its drawbacks. Therefore, we recommend B2P to incorporate this new design for future production of the Power Liftgate Motor System.

As the planetary gear system has more points of contact between components as shown in the new Boundary Diagram, it means that there is now a lower tolerance range for piece to piece variation. This translates to a higher manufacturing cost we have mentioned in the cost analysis. However, we have also mentioned that the increase in manufacturing cost was offset by a reduction in material cost. Furthermore, from the simplified QFD shown in Table 3, we can see that the target of achieving minimal piece to piece variability is only has an importance rating of 31. From the two aforementioned factors, we can conclude that the decrease in piece-to-piece variability does not pose a big problem.

Table 3: Simplified Quality Flow Chart Potential Failure Mode

To further affirm the convenience of implementing the new design, we figured out what interest rate would be required to make the new design less profitable than the original design. That means we found the yearly interest rate necessary in order for NPVoutflow original < NPVoutflow new. In order to do this, we first solved for the interest rate such that

Item and Function / Requirements

In order for the new design to be more profitable we want NPVsavings to be a positive value. We first assumed an interest rate, i, of 8 %. Substituting in all of our values (where i = .08 and D = $298,800), we get NPVsavings = $993,021.76. This is a large positive value, and it represents how much money will be saved over a five year period in terms of NPV.

By changing the material of the mounting plate from low carbon steel to ABS plastic, there is a greater chance of the plastic breaking in a direct collision as its material strength is much lower than that of steel’s. Even though our previous stress analysis has shown that ABS plastic’s tensile strength is strong enough for use, we do not know if the integrity of the material can be maintained under crash conditions. However, it must be mentioned that firstly, such situations are rare as they only occur when the car undergoes a collision that affects the PLG. This factor is represented by a low occurrence value of 1 in the simplified DFMEA shown in Table 2. Secondly, the car will almost definitely undergo repairs and checks for damages after a collision, resulting in easy detection. This is represented by a low detection value of 2 in the DFMEA. The combination of the two values above and a mid-range severity value of 5 results in a relatively low RPN of 10. With that, we can safely say that the potential failure mode of the mounting plate breaking does not pose a big problem.

same. Furthermore, the low importance rating of 15 shown in simplified QFD above means that this target is relatively less important when put alongside with other targets. From the two aforementioned factors, we can conclude that the increase in maintenance cost does not pose a big problem.

matrix. The three constraints that we will be evaluating are the durability of the mounting plate, piece-to-piece variability and maintenance costs. The evaluation includes possible failure modes and drawbacks, followed by an analysis of the failure modes and drawbacks using the QFD and DFMEA. For example, if the RPN of the failure mode are low, it poses a small problem even if there are new failure modes being introduced. Likewise, if the Importance rating of the drawback is low, it poses a small problem.

would determine whether it is better to invest money in this project or to place the same amount of money in a bank. To make this as accurate as possible, we must use values for the NPV in relation to the current casing so that we can determine how much money is actually saved. We will assume that the inflows for both models remain the same and occur at the same time. However, the outflows will be different. We let Cinit represent the yearly outflows of the original model and let D represent the money saved each year by using the proposed design. All of our calculations are based on a five year period.

As the planetary gear system is relatively more complex as compare to the standard gear train, it would result in poorer accessibility. This would mean that there would be an increase in maintenance costs spent by B2P. However, this is offset by the fact that the gear system is now more durable (maintenance cost = units sent in for maintenance x maintenance cost of each unit). This would mean that overall maintenance cost would probably remain the

Self Powered Relays

Self Powered Relays

Introduction The distribution network is generally operated in open loop allowing a backup solution in case of fault. It is historically equipped with manual switches, with only one protection device per feeder, located in the Medium Voltage/ Medium Voltage (MV/MV) substation. In case of fault, all the Medium Voltage/Low Voltage (MV/LV) substations supplied by the faulty feeder are disconnected. The use of circuit breaker instead of ring switches in the loop allows disconnecting only the customers connected to the faulty part, which is significant benefit regarding the number of affected customers compared to the traditional solutions. There were constraints in implementing circuit breakers in the secondary distribution network: i. Medium voltage circuit breakers and their associated equipment were expensive and more customized to High Voltage/ Medium Voltage (HV/MV) substation than to MV/LV substation (package substation). ii. Usual time discrimination protection system led to a limitation of the number of discrimination levels. iii. Auxiliary supply was required for protective relays. Digital relays and modern circuit breakers along with several improvements of the existing protection system allow insertion of one or two protection stages without long clearing time. The time discrimination can be 58



Ring Main Unit Switchgear And Self-Powered Relays The first ring main units appeared in the 1950s were oil ring main units with typical three function repetitive arrangement. The traditional switching cells were substituted with complete switchgear systems. For more compactness, the three functions have been fitted in one metallic tank. In the last 20 years, the RMU switchgears have been area of significant development. Specific functions such as grounding, disconnecting, cable connections, busbar extension, protection and switching have become integral features in compact functional units. Compact switchgear systems fulfill MV application requirements. The numerous distribution substations demanded a unified switching functionality that progressed into ring main unit concept. The ring main unit is a standard piece of switchgear in secondary distribution system comprising of switches for switching power cable rings and of switches in series with high rupturing capacity fuses or circuit breakers for the protection of distribution transformers. Each RMU may consist of a total of 3 to 6-way switch box composition, flexible to meet the different distribution network node needs. All the switching devices are enclosed in one SF6 gas filled stainless steel tank at a pressure of 1.4 MPa. The SF6 gas is used as an arc-quenching and insulating medium. The 12/15/24 kV rating ring main units are available in 15 different configurations and 36 kV rating ring main units are available in five different configurations suitable for most switching applications in the distribution networks. The RMUs are used as indoor or outdoor medium voltage switchgear board as well as medium voltage switchgear in the MV/LV substation. Different configurations of ring main unit for the secondary distribution application are shown in Figure 1. ring main feeders + 2 1 transformer feeder

Typical RMU arrangement with fuse-switch and circuit breaker for transformer protection is shown in Figure 2 in package substation.

The Table 1 shows that fuse-switch application is limited to transformers feeders up to 1600 kVA rating. Whereas circuit breakers can be used for incoming and outgoing ring feeders and up to 12 MVA transformer feeders.

Incomers

The self-powered feeder protection relays are mainly designed for the selective short circuit and earth fault protection of feeders in secondary distribution networks and for the protection of distribution transformers in power utilities and industries. These relays do not require external auxiliary power source or batteries. The relays derive power supply voltage for its operation from the current transformers. In remote areas or where auxiliary supplies are not available; self-powered protection relays are the best solution for protection requirements of feeders and transformers. The self-powered relay in combination with circuit breaker is replacing the traditional practice of using load break switch with high voltage fuses (fuseswitch) for transformer protection due to its advantageous characteristics. This paper highlights application of ring main units with circuit breakers in secondary distribution and focuses on application, important characteristics, and testing of self-powered relays in Medium Voltage/Low Voltage (MV/LV) substations, indoor, and outdoor ring main units.

reduced to 200 ms. The logic discrimination can be used in substations between incoming and outgoing feeders. This principle allows same time setting for both stages. The development and introduction of SF6 gas or vacuum circuit breaker in the Ring Main Unit (RMU) switchgear as tee-off point and as incoming or outgoing feeder in the loop also opened new area of protection relays. The selfpowered protection relays which do not require batteries fulfill requirement of reliable protection for ring and tee-off feeders with maximum economy.

circuit breakers and self-powered relays have the same life time costs as fuse-switch solutions and have far more useful features. Therefore, trend is shifted towards the use of circuit-breakers instead of fuse-switches for tee-off transformer feeders.In the transformers low magnitude fault occur which at later stage is converted to high magnitude fault, for example an inter-turn fault.  A fuse would be unable to clear the fault, whereas a circuit-breaker works perfectly on something that is similar to an overload. Also, even on high magnitude faults, circuit-breakers function well, clearing faults quickly enough. Self-powered relays are simple and easy to set. Also, settings can be changed as the installation evolves.  This removes doubt over the selection of the proper fuse when replacement is needed either after a fault or for other reasons. Upstream and downstream coordination is much easier with circuitbreakers. Network management is better facilitated. In case of a fault on the network, the overall time, including fault finding up to re-energizing is reduced with circuitbreakers compared to the use of fuse-switch solutions.

Self Powered Relays

Self Powered Relays jeopardize protection of protected equipment. Therefore, in tropical countries where declared ambient temperature by utilities and industries reaches up to 55 °C; these relays shall be selected carefully according to their application. The operating, storage and transport temperature of relays from various manufacturers are compared in Table 3. Figure 3 – Selfpowered relays from various manufacturers for RMU feeder and transformer protection

In RMU type CCV, vacuum circuit breaker in combination with self-powered protection relay type WIC1 having 50/51 and 51N protections for distribution transformer protection is shown in Figure 4.

with conventional 1A/5A CTs. Mostly, conventional CTs are not used with self-powered relays. Depending on the rated primary power and voltage of the system, the current transformers mentioned in Table 2 can be used. In order to operate reliably, all CT powered protection relays need a minimal current flowing constantly in one of the phases. This minimal current is the smallest rated CT current which is 0.9Is in one phase or 0.3Is in all the three phases.

Operating, Storage And Transport Temperature The temperature rise of an electrical apparatus is a design parameter that is verified during type test. The operating temperature of self-powered relays is a limiting factor for their application as indoor or outdoor protective device. The relays having operating temperature range up to 55 °C are suitable for indoor application. In general, the relays with LCD display have lower operating temperature which restricts their application for indoor switchgear only. For outdoor applications such as outdoor RMUs and MV/LV substations; relays having maximum operating temperature of 70 °C or higher are suitable. CT Type / Relay Figure 4 –RMU type CCV in combination with relay type WIC1 for transformer protection

Current Transformers For Self-Powered Relays These relays are provided with three analog measuring inputs (3 x phase current). The current measuring inputs are especially adjusted to the current transformers allocated to the protection system. The relays provide earth current measurement through internal calculation or have the provision for measuring it from the external core balance current transformer. As an example, CTs for WIC1 and REJ603 relays are shown in Table 2 having five different CT ratios available which are conditional on system rated current. These CTs are not compatible 60

Switch-On-To-Fault Characteristics When these relays switch on to a fault, the operating time will be extended by 30 ms to 40 ms depending on the fault current level and type of relay. The Switch-on-to-fault characteristics for REJ603 relay at 0.9Is is shown in Figure 5. At the minimum value of pick-up current and minimum operating time, the minimum value of the tripping time at switch-on-to-fault is ≤ 80 ms at I/In ≥ 5.

Self Powered Relays considered that overall error will be error of relay and CT together and the error of testing equipment.

Relay Commissioning Like any feeder and transformer protection relay; power system coordination study, relay-setting calculation and final setting are mandatory requirements for proper function of self-powered protection relays. Normally, the relays are supplied with a factory-set default setting, which have no relation with the final setting of relays. The users are responsible for determining the application-specific settings applied to the relay, pre-commissioning checks as per manufacturer’s instruction and testing of relay at final setting.

Conclusions The RMUs are used in medium voltage from 11 kV to 36 kV ring distribution system in any power distribution network. The RMUs offer greater flexibility in supply system in maintaining continuity of supply. They offer practically maintenance-free operation. The RMUs are very compact in size compared with MV switchgear panels. The most common versions of RMU are 3-way and 4-way Extensible and Non-extensible types. The introduction and use of circuit breakers in the RMU in place of ring switches and transformer fuse-switches opened the door for self-powered protection relays. The advantage of selfpowered protection relays is that they do not need any auxiliary power supply. The relay and the tripping unit of circuit breaker receive their energy from the current transformers. CT powered relays need a minimal current flowing constantly in three phases or one of the phases for their operation. Therefore, selection of CTs having proper current rating according to the requirement is very important for reliable operation. In tropical countries, for outdoor RMUs and MV/LV package substations; maximum operating temperature of relays is considered during their selection. The pickup current, operating time and switchon to fault condition are verified during routine test of relay by the relay manufacturer. During the commissioning, the final settings are applied and all the protection functions tested to ensure healthiness of protection before energization. During field maintenance tests, the function of relay may be checked through test winding to simulate primary current. Current can be injected in the test winding of current transformers through test sockets if available. It facilitates the testing of complete protection scheme including current transformer, relay and trip coil of circuit breaker.

Action is the foundational key to all success. Pablo Picasso

Success

progress; working together is success. Henry Ford

In order to succeed, your desire for success should be greater than your fear of failure. Bill Cosby Always be yourself, express yourself, have faith in yourself, do not go out and look for a successful personality and duplicate it. Bruce Lee A successful man is one who can lay a firm foundation with the bricks others have thrown at him. David Brinkley Success is not final, failure is not fatal: it is the courage to continue that counts. Winston Churchill Try not to become a man of success, but rather try to become a man of value. Albert Einstein Always bear in mind that your own resolution to succeed is more important than any other. Abraham Lincoln Coming together is a beginning; keeping together is 80

Computer Engineers



Strive not to be a success, but rather to be of value. Albert Einstein I›ve failed over and over and over again in my life and that is why I succeed. Michael Jordan All you need is ignorance and confidence and the success is sure. Mark Twain Success is a lousy teacher. It seduces smart people into thinking they can›t lose. Bill Gates I don›t know the key to success, but the key to failure is trying to please everybody. Bill Cosby Develop success from failures. Discouragement and failure are two of the surest stepping stones to success. Dale Carnegie The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack of will. Vince Lombardi

Leadership

People ask the difference between a leader and a boss. The leader leads, and the boss drives. Theodore Roosevelt

If you think you can do a thing or think you can›t do a thing, you›re right. Henry Ford A genuine leader is not a searcher for consensus but a molder of consensus. Martin Luther King, Jr. It is better to lead from behind and to put others in front, especially when you celebrate victory when nice things occur. You take the front line when there is danger. Then people will appreciate your leadership. Nelson Mandela A leader is best when people barely know he exists, when his work is done, his aim fulfilled, they will say: we did it ourselves. Lao Tzu Leadership is solving problems. The day soldiers stop bringing you their problems is the day you have stopped leading them. They have either lost confidence that you can help or concluded you do not care. Either case is a failure of leadership. Colin Powell Effective leadership is not about making speeches or being liked; leadership is defined by results not attributes. Peter Drucker Be a yardstick of quality. Some people aren›t used to an environment where excellence is expected. Steve Jobs 82



Don›t find fault, find a remedy. Henry Ford Leadership is the art of getting someone else to do something you want done because he wants to do it. Dwight D. Eisenhower Innovation distinguishes between a leader and a follower. Steve Jobs Effective leadership is putting first things first. Effective management is discipline, carrying it out. Stephen Covey Management is doing things right; leadership is doing the right things. Peter Drucker Affirmation without discipline is the beginning of delusion. Jim Rohn Leadership - leadership is about taking responsibility, not making excuses. Mitt Romney A man always has two reasons for doing anything: a good reason and the real reason. J. P. Morgan Hold yourself responsible for a higher standard than anybody expects of you. Never excuse yourself. Henry Ward Beecher The cautious seldom err. Confucius

The RF Spectrum -- An Overview

T

he term Radio Frequency (RF or rf) refers to the electromagnetic field that is generated when an alternating current is input to an antenna. This field, also called an RF field or radio wave, can be used for wireless broadcasting and communications over a significant portion of the electromagnetic radiation spectrum -- from about 9 kilohertz (kHz) to thousands of gigahertz (GHz). This portion is referred to as the RF Spectrum. As the frequency is increased beyond the RF spectrum, electromagnetic energy takes the form of infrared (IR), visible light, ultraviolet (UV), X rays, and gamma rays.  Many types of wireless devices make use of RF fields -- radio, television, cordless and cellular telephones, satellite communication systems, and many measuring and instrumentation systems used in manufacturing. Some wireless devices, such as remote control boxes and cordless mice, operate at IR or visible light frequencies. The RF spectrum is divided into several ranges, or bands. Each of these bands, other than the lowest frequency segment, represents an increase of frequency corresponding to an order of magnitude (power of ten). The chart below depicts the eight bands in the RF spectrum, showing frequency and bandwidth ranges.

Maths Interesting Facts  The word ‘mathematics’ comes from the Greek máthēma, which means learning, study, science.  What comes after a million, billion and trillion? A quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and undecillion.  Different names for the number 0 include zero, nought, naught, nil, zilch and zip.  Zero ( 0 ) is the only number which can not be represented by Roman numerals.  The name ‘zero’ derives from the Arabic word sifr which also gave us the English word ‘cipher’ meaning ‘a secret way of writing’ .  Do you know the magic of no. nine (9)? Multiply any number with nine (9 ) and then sum all individual digits of the result (product) to make it single digit, the sum of all these individual digits would always be nine (9).  Here is an interesting trick to check divisibility of any number by number 3.A number is divisible by three if the sum of its digits is divisible by three (3).  The = sign (“equals sign”) was invented by 16th Century Welsh mathematician Robert Recorde, who was fed up with writing “is equal to” in his equations.  Googol (meaning & origin of Google brand ) is the term used for a number 1 followed by 100 zeros and that it was used by a nine-year old, Milton Sirotta, in 1940.  Abacus is considered the origin of the calculator.  Have you ever noticed that the opposite sides a die always add up to seven (7).  12,345,678,987,654,321 is the product of 111,111,111 x 111,111,111. Notice the sequence of the numbers 1 to 9 and back to 1.  Plus (+) and Minus (-) sign symbols were used as early as 1489 A.D.  An icosagon is a shape with 20 sides.  Trigonometry is the study of the relationship between the angles of triangles and their sides.  If you add up the numbers 1-100 consecutively (1+2+3+4+5...) the total is 5050.  2 and 5 are the only primes that end in 2 or 5.  From 0 to 1,000, the letter “A” only appears in 1,000 (“one thousand”).  A ‘jiffy’ is an actual unit of time for 1/100th of a second.  ‘FOUR’ is the only number in the English language that is spelt with the same number of letters as the number itself 122
