Book SynopsisThe essential guide that combines power system fundamentals with the practical aspects of equipment design and operation in modern power systems Written by an experienced power engineer, AC Circuits and Power Systems in Practice offers a comprehensive guide that reviews power system fundamentals and network theorems while exploring the practical aspects of equipment design and application. The author covers a wide-range of topics including basic circuit theorems, phasor diagrams, per-unit quantities and symmetrical component theory, as well as active and reactive power and their effects on network stability, voltage support and voltage collapse. Magnetic circuits, reactor and transformer design are analyzed, as is the operation of step voltage regulators. In addition, detailed introductions are provided to earthing systems in LV and MV networks, the adverse effects of harmonics on power equipment and power system protection. Finally, European and American engineering standards are presTrade ReviewThis book combines the author�s rich experience in industry and teaching expertise in university. It covers the fundamental topics of AC circuits, and the application of those theories are discussed with numerous examples as well as the requirements of Engineering Standards. The writing style is logical and explicit, while illustrations and diagrams are with great accuracy, facilitating readers to have a systematic and in-depth understanding. Overall, I think this book can be an invaluable guide for recent graduate engineers working in power industry. -- Adrian Chen, Electrical Engineer, Moolarben Coal Operations Pty Ltd, Australia This is a refreshingly practical text which covers a wide range of topics relating to AC power systems. The book is divided into two parts with part one providing a broad overview of AC power systems and a review of fundamental AC circuit theory. Part two of the book covers specific areas of AC power systems in more detail with chapters on three phase transformers, voltage and current measurement, energy metering, harmonics and power system protection. One standout feature of this book is the writing style which I found to be very straight forward and easy to read. Additionally, excellent diagrams and illustrations work well to reinforce the subject material. The text is very well referenced with a list of sources provided at the conclusion of each chapter. The industry based examples in the text work well to link electrical engineering theory and practice and as such this book should find appeal with both undergraduate students studying a course of electrical engineering and recent graduates. - James Lamont, Electrical Engineering Technical Officer, Deakin University, Australia The genius of the text is that it presents sound theoretical concepts in a practical, easy to apply manner. The use of phasor diagrams and illustrated examples makes the application to real world problems easier, and gives the practitioner a �feel� for the solution – a valuable and necessary outcome in situations where not all the information is easily available and decisions must still be made. - David Gaskell, Nyrstar Hobart Smelter, AustraliaTable of ContentsPreface xiii Acknowledgements xvii

Book SynopsisA practical guide to facilitate statistically well-founded decisions in the management of assets of an electricity grid Effective and economic electric grid asset management involves many complex decisions on repair, replacement and maintenance.Trade ReviewRobert Ross�s book gives a deep insight in useful statistical analysis methods for asset management practice. It covers all the basics and specific distributions in a structured and understandable way, before it sets out to give its insight into system and component reliability. I particularly liked the way the subject matter is structured in small and understandable topics. This way it�s easy to �pick and mix� throughout the different subject matters of the book to acquire the relevant knowledge. One of the other strong suits of the book is the application to real life asset and incident management. Robert links theory and practice together in a way which really shows the value of a statistical and reliability driven approach to asset management. - Marcel Hooijmans, Sr. Specialist Asset Management, Stedin DSO, The Netherlands This is a well-grounded book that is really good to read! It is informative and accessible and something that would be suitable as a source book for a more general course on engineering statistics and not one specifically directed towards electric power grid assets. Overall the book develops a very solid statistical basis of use in engineering and, particularly reliability analysis. I believe the book is of such general value that it could be used as part of a manufacturing engineering course with relative ease. I think this should probably be on the bookcase of anyone working in asset management of utilities. The material is presented with a logical and paced approach, taking the reader through basic statistics to some quite advanced concepts. - Professor Alistair Duffy, Professor of Electromagnetics and Director of the Institute of Engineering Sciences at De Montfort University, Leicester, UK Robert Ross creates a comprehensive interface between the statistical analysis and the Asset Management tasks and problems of the electric grid. Many practical examples give a clear and easy understanding of the different subjects�the book is suitable for a direct entry into the topic. Later it can also be used as a reference work, particularly regarding the synoptic tables. This makes the book ideal for students as well as for practical use by asset managers. - Dr. Horst Günter Bender, TenneT TSO GmbH, Germany The book features ten chapters, with the main focus on the fundamentals of statistics. The way the book is written makes it possible to be used as supplement to lectures at universities about asset management because of the following points. Each chapter features an introductory paragraph and a section at the end with a summary of the topics covered by that chapter. Furthermore, each chapter provides exemplary questions and exercises which facilitate understanding of the chapter. Additionally, the author supports his argumentation with easily understandable practical examples from the field of electrical engineering. - Nicholas Hill, TU Braunschweig, Germany Anybody working in asset and incident management of electric power grids will greatly welcome this book if they want to understand and apply the mathematics used for assessing the reliability and availability of components and systems. The author makes a decisive step forward in presenting the knowledge and skills needed for analyzing failure data and constructing reliable systems. Throughout the book, readers can taste the thorough experience of Ross both as a practitioner and as a researcher in the field of reliability analysis.

Book SynopsisWeaves together personal narrative, historical research, cultural analysis, and social science to provide a sweeping investigation of the varied influence of overhead wires on the American landscape and the American mind.Trade Review"Focusing on the network of wires that connect energy, place, and culture in the United States, Daniel Wuebben's well-composed meditation on the vinelike web of overhead power lines offers a rich and compelling account of the ambiguities, tensions, and ironies associated with this often-overlooked piece of critical infrastructure. Power-Lined: Electricity, Landscape, and the American Mind is a welcome addition to the energy humanities and social sciences literature with its engaging exploration of the modern imaginaries that inspired the US transmission grid's design as well as the anxieties that accompanied the expansion of overhead lines across the Great Plains and beyond."—Melissa Bollman, Great Plains Quarterly"Wuebben is provocative and pragmatic about balancing aesthetic interests with the practical realities of an infrastructural item that has become an essential, pervasive part of modern life."—D. Mitch, Choice"Reading Wuebben's work is a rich experience. One particular strength lies in his showing how power and telegraph lines appear in places one would not expect."—A. David Wunsch, IEEE Technology and Society Magazine"Wuebben's study deserves attention by anyone interested in the effects of technology on society and culture. It is a unique and innovative analysis."—R. Douglas Hurt, Journal of the Illinois State Historical Society“Daniel Wuebben invites the reader to gaze at the transmission lines crisscrossing our landscape and imagine not only the technology behind the infrastructure but also the politics and poetics of electrifying our country. With historical detail and carefully constructed analysis, Wuebben offers an engaging narrative that fills important gaps in our understanding of the power grid and its physical and cultural ramifications for the twenty-first century.”—Julie A. Cohn, author of The Grid: Biography of an American Technology“Daniel Wuebben’s Power-Lined makes a valuable contribution to understanding the crucial place of technology in the relationship between people and the natural world. As he reveals in this measured study of electric power lines, the relationship between people and nature is always dynamic, interactive, complex, and messy.”—James C. Williams, author of Energy and the Making of Modern California“In this eloquent and engaging new book, Daniel Wuebben sheds light on a ubiquitous yet often-overlooked aspect of electrical development: the power lines themselves. This capacious book incorporates the history of technology, literature and cinema studies, and art history in chronicling the history of our wired world, from the stringing of telegraph cables through the development of a smart grid. The result of his impressive attention to detail is a book that will enlighten any reader who is interested in technology, literature, and culture.”—Jennifer L. Lieberman, author of Power Lines: Electricity in American Life and Letters, 1882–1952“Power-Lined has the potential to link several fields of study: history of technology, American studies, literature, design, and art history. This is an important subject, and the author tackles it quite well. . . . It’s very readable and entertainingly written.”—David Hochfelder, author of The Telegraph in America, 1832–1920Table of ContentsList of Illustrations Preface: Playing Power Lines Introduction: Power-Lined Landscapes 1.

Book SynopsisIn India over the past century, electrification has meant many things: it has been a colonial gift of modern technology, a tool of national integration and political communication, and a means of gauging the country''s participation in globalization. Electric lights have marked out places of power, and massive infrastructures have been installed in hopes of realizing political promises. In A Moral Technology, the grids and wires of an urban public utility are revealed to be not only material goods but also objects of intense moral concern. Leo Coleman offers a distinctive anthropological approach to electrification in New Delhi as more than just an economic or industrial process, or a gridding of social and political relations. It may be understood instead as a ritual action that has formed modern urban communities and people's sense of citizenship, and structured debates over state power and political legitimacy.Coleman explores three historical and ethnographic case studiesTrade Review"Developing nuanced and valuable readings of critical moments in the story of electrification in Delhi/New Delhi, Leo Coleman suggests that electricity far exceeds its formal role as infrastructure. He persuasively argues that the ideological burden and meaning of electricity informs its physical distribution (from where it is introduced and who gets it first to how the grid is controlled or the ownership of electric meters understood), while demonstrating how political associations, relationships, and networks are imagined, cast, and reconfigured through the distribution of electricity." -- Ritika Prasad, University of North Carolina–Charlotte, author of Tracks of Change: Railways and Everyday Life in Colonial IndiaTable of ContentsIntroduction: Electricity ActsPart I.

Book SynopsisIn the 2000s, Laos was treated as a model country for the efficacy of privatized, sustainable hydropower projects as viable options for World Bank-led development. By viewing hydropower as a process that creates ecologically uncertain environments, Jerome Whitington reveals how new forms of managerial care have emerged in the context of a privatized dam project successfully targeted by transnational activists. Based on ethnographic work inside the hydropower company, as well as with Laotians affected by the dam, he investigates how managers, technicians and consultants grapple with unfamiliar environmental obligations through new infrastructural configurations, locally-inscribed ethical practices, and forms of flexible experimentation informed by American management theory.Far from the authoritative expertise that characterized classical modernist hydropower, sustainable development in Laos has been characterized by a shift from the risk politics of the 1990s to an ontologicaTrade ReviewWhitington's book analyses a period of unprecedented hydropower development during which the country effectively doubled its major dams.

Book SynopsisThis book reviews the past, present and future generation and use of electricity. While noting the importance of electricity to the well-being of people, it argues that all means of electricity generation have adverse ecological consequences. The ecological effects of all the main forms of electricity generation, storage and transmission are reviewed in 14 chapters. The chapters briefly cover the engineering and physics of each method of electricity generation followed by a description of the different ways in which the technology interacts with the natural world. Finally, sections consider the importance of these impacts and how they can be mitigated or avoided. A final chapter summarizes the issues and emphasizes that the only way to truly minimize the impacts of electricity generation is to reduce our consumption and transmission. Future efforts should continue to focus on increasing the efficiency of light production, refrigeration, electrical appliances and batteries.Table of Contents1: Our Need for Electricity and the Main Energy Sources Available 2: Hydroelectric Generation 3: Tidal Generation 4: Wave Power and Ocean Thermal Energy Conversion 5: Steam Turbines and Their Cooling Systems 6: Nuclear Generation 7: Coal and Oil-Fired Power Plants 8: Gas-Fired Power Plants 9: Wind Turbines and the Effects of Offshore Piling 10: Solar Power 11: Fuel Cells and Flow Batteries 12: Batteries 13: Biofuels and Waste-Powered Generation 14: Small-Scale and Mobile Electric Generators 15: Ecological Issues Relating to Transmission Lines 16: Geothermal Generation 17: Minimizing Environmental Damage While Generating Electricity Cost-Effectively

Book SynopsisExamines the history of electricity provision in Africa and the effects of privatization and infrastructure changes in energy transformation, offering a critical window into development politics in African states. No country has managed to develop beyond a subsistence economy without ensuring at least minimum access to electricity for the majority of its population. Yet many sub-Saharan African countries struggle to meet demand. Why is this, and what can be done to reduce energy poverty and further Africa's development? Examining the politics and processes surrounding electricity infrastructure, provision and reform, the author provides an overview of historical andcontemporary debates about access in the sub-continent, and explores the shifting role and influence of national governments and of multilateral agencies in energy reform decisions. He describes a challenging political environment for electricity supply, with African governments becoming increasingly frustrated with the rules and the processes of multilateral donors. Civil society also began to question reform choices, and governments in turn looked to new development partners, such as China, to chart a fresh path of energy transformation. Drawing on over fifteen years of research on Uganda, which has one of the lowest levels of access to electricity in Africa and has struggled to construct several, large hydroelectric dams on the Nile, Gore argues that there is a critical need to recognize how the changing political and social context in African countries, and globally, has affected the capacity tofulfil national energy goals, minimize energy poverty and transform economies. Christopher Gore is Associate Professor, Department of Politics and Public Administration, Ryerson University, Toronto, Canada. OA EDITION This book has been made available as Open Access through the support of the Office of the Dean, Faculty of Arts, Ryerson University; Ryerson International; and the Department of Politics and Public Administration, Ryerson University.Trade Review... should appeal to scholars not only of energy and electricity policy but also of socio-technical transitions and African studies. What is particularly impressive is the attention to the micro-politics of electricity sector reform processes in Uganda whilst drawing on an impressively eclectic range of theoretical resources. -- Peter Newell, Professor of International Relations, University of SussexChristopher Gore's lively new book, Electricity in Africa, is an excellent case study of one of the continent's most pressing issues: energy availability and consumption. Based on over a decade and a half of research and interviews, Electricity in Africa, part of the praiseworthy African Issues series, reveals the emerging scholarship of energy studies in East Africa, focusing on Uganda because of its uniquely bleak energy situation. Despite its increasing population, Uganda has suffered from one of the lowest levels of electricity access in Africa, and Gore provides a thorough examination of how and why this has occurred. * JOURNAL OF GLOBAL SOUTH STUDIES *Electricity in Africa helps us understand the complexity of electricity sector reforms. Gore has interacted with many of the key stakeholders in government and in the development community and has a deep understanding of the specifics of the sector as well as of its history and the Uganda context. * COMMONWEALTH & COMPARATIVE POLITICS *Christopher Gore's book is a good step in the direction of the desired continental synthesis of two decades of political economy in relation to electricity in African countries.

Book SynopsisThis book investigates the fabrication of different types of flexible sensors and their subsequent implementation for energy-harvesting applications. A range of techniques, including 3D printing, soft lithography, laser ablation, micro-contract printing, screen-printing, inkjet printing and others have been used to form the flexible sensors with varied characteristics. These sensors have been used for biomedical, environmental and healthcare applications on the basis of their performances. The quality of these flexible sensors has depended on certain types of nanomaterials that have been used to synthesize the conductive parts of the prototypes. These nanomaterials have been based on different sizes and shapes, whose quality varied on the basis of certain factors like crystallinity, shapes and sizes. One of the primary utilization of these nanotechnology-based flexible sensors has been the harvesting of energy where nano-generators and nano-harvesters have been formed to generate and store energy, respectively, on small and moderate magnitudes. Mechanical and thermal energies have been harvested on the basis of the piezoelectric, pyroelectric and triboelectric effects created by the formed prototypes. The work highlights the amalgamation of these sectors to spotlight the essence of these types of sensors and their intended application.

Book SynopsisThis book covers cutting edge advancements on self-powered Internet of Things, where sensing devices can be energy-positive while capturing context from the physical world. It provides new mechanisms for activity recognition without the need of conventional inertial sensors, which demand significant energy during their operation and thus quickly deplete the batteries of internet-of-things (IoT) devices. The book offers new solutions by employing energy harvesters as activity sensors as well as power sources to enable the autonomous and self-powered operation of IoT devices without the need of human intervention. It provides useful content for graduate students as well as researchers to understand the nascent technologies of human activity, fitness and health monitoring using autonomous sensors. In particular, this book is very useful for people working on pervasive computing, activity recognition, wearable IoT, fitness/healthcare and autonomous systems.This book covers a broad range of topics related to self-powered activity recognition. The main topics of this book include wearables, IoT, energy harvesting, energy harvesters as sensors, activity recognition and self-powered operation of IoT devices. This book starts with the introduction of wearable IoT devices and activity recognition and then highlights the conventional activity recognition mechanisms. After that, it describes the use of energy harvesters to power the IoT devices. Later, it explores the use of various energy harvesters as activity sensors. It also proposes the use of energy harvesters as simultaneous source of energy and context information and defines the emerging concept of energy-positive sensing compared to conventional energy-negative sensing. Finally, it explores sensor/signal fusion to enhance the performance using multiple energy harvesters and charts a way forward for future research in this area. This book covers all important and emerging topics that have significance in the design and implementation of autonomous wearable IoT devices. We believe that this book will lay the foundation for designing self-powered IoT devices which can ultimately replace the conventional wearable IoT devices which need regular recharging and replacement.Table of ContentsIntroduction.- Background.- Energy harvesting to power the IoT devices.- Energy harvesters as activity sensors.- Energy harvesters as a simultaneous source of energy and activity information.- Energy-Positive Activity Recognition.- Fusion of multiple energy harvesters.- Conclusion and Future Work.

Book SynopsisThis book describes recent breakthroughs that promise major cost reductions in solar energy production in a clear and highly accessible manner. The authors address the three key areas that have commonly resulted in criticism of solar energy in the past: cost, availability, and variability. Coverage includes cutting-edge information on recently developed 40 efficient solar cells, which can produce double the power of currently available commercial cells. The discussion also highlights the potentially transformative emergence of opportunities for integration of solar energy storage and natural gas combined heat and power systems. Solar energy production in the evening hours is also given fresh consideration via the convergence of low cost access to space and the growing number of large terrestrial solar electric power fields around the world.Dr. Fraas has been active in the development of Solar Cells and Solar Electric Power Systems for space and terrestrial applications since 1975. His research team at Boeing demonstrated the first GaAs/GaSb tandem concentrator solar cell in 1989 with a world record energy conversion efficiency of 35, garnering awards from Boeing and NASA. He has over 30 years of experience at Hughes Research Labs, Chevron Research Co, and the Boeing High Technology Center working with advanced semiconductor devices. In a pioneering paper, he proposed the InGaP/GaInAs/Ge triple junction solar cell predicting a cell terrestrial conversion efficiency of 40 at 300 suns concentration. Having become today’s predominant cell for space satellites, that cell is now entering high volume production for terrestrial Concentrated Photovoltaic (CPV) systems. Since joining JX Crystals, Dr. Fraas has pioneered the development of various thermophotovoltaic (TPV) systems based on the new GaSb infrared sensitive PV cell.
