    John Wiley & Sons Inc Current Signature Analysis for Condition

    Book SynopsisProvides coverage of Motor Current Signature Analysis (MCSA) for cage induction motors This book is primarily for industrial engineers. It has 13 chapters and contains a unique data base of 50 industrial case histories on the application of MCSA to diagnose broken rotor bars or unacceptable levels of airgap eccentricity in cage induction motors with ratings from 127 kW (170 H.P.) up to 10,160 kW (13,620 H.P.). There are also unsuccessful case histories, which is another unique feature of the book. The case studies also illustrate the effects of mechanical load dynamics downstream of the motor on the interpretation of current signatures. A number of cases are presented where abnormal operation of the driven load was diagnosed. Chapter 13 presents a critical appraisal of MCSA including successes, failures and lessons learned via industrial case histories. The case histories are presented in a step by step format, with predictions and outcomes supported by cuTable of ContentsABOUT THE AUTHORS xiii OBITUARY TO IAN CULBERT xv ACKNOWLEDGMENTS xvii FOREWORD

    Book SynopsisAn essential guide to the stability and control of power systems integrating large-scale renewable energy sources The rapid development of smart grids and the integration of large scale renewable energy have added daunting new layers of complexity to the long-standing problem of power system stability control. This book offers a systematic stochastic analysis of these nonlinear problems and provides comprehensive countermeasures to improve power system performance and control with large-scale, hybrid power systems. Power system stability analysis and control is by no means a new topic. But the integration of large scale renewable energy sources has added many new challenges which must be addressed, especially in the areas of time variance, time delay, and uncertainties. Robust, adaptive control strategies and countermeasures are the key to avoiding inadequate, excessive, or lost loads within hybrid power systems.

    Book SynopsisIntroduces readers to micro and local power markets and their use for local initiatives, grid integration, and future applications This book provides the basis for understanding micro power markets, emphasizing its application for local initiatives, the grid integration of renewable-based generation, and facilitating the decarbonization of the future electrical networks. It gives readers a comprehensive overview of the market operation, and highlights the basis of the design of local and micro markets. Micro and Local Power Markets starts by covering the economics and basic principle of power markets, including the fundamentals of the power trading (for both wholesale and local markets). Following a definition of both micro and local (technical and economic aspects) power markets, the book then looks at the organization of such markets. It describes the design of those power markets, isolated from the wholesale markets, and examines the methodologies of the interaction between theseTable of ContentsList of Contributors xi Foreword xiii Preface xv 1 Power Market Fundamentals 1Íngrid Munné-Collado, Pol Olivella-Rosell and Andreas Sumper 1.1 Introduction 1 1.2 Basic Design of Power Markets 5 1.2.1 Organization 5 1.2.1.1 Monopoly 5 1.2.1.2 Purchasing Agency 5 1.2.1.3 Wholesale Market 5 1.2.1.4 Retail Competition 7 1.2.2 Bilateral Contracts and Auctions 7 1.2.3 Clearing 10 1.2.4 Settlement or Pricing 10 1.2.5 Example 11 1.3 Mechanism for Auctions 13 1.3.1 Why Auctions in Energy Markets?

    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.

    Book SynopsisThis second edition introduces the theory and applications of the modulation transfer function (MTF), used to specify the image quality achieved by an imaging system. It starts with the relationship between impulse response and transfer function, and the implications of a convolutional representation of the imaging process. Optical systems are considered first, including effects of diffraction and aberrations on the image, with attention to aperture and field dependences. Then electro-optical systems with focal-plane arrays are considered, with an expanded discussion of image-quality aspects unique to these systems, including finite sensor size, shift invariance, sampling MTF, aliasing artifacts, crosstalk and electronics noise. Various test configurations are then compared in detail, considering the advantages and disadvantages of point-response, line-response and edge-response measurements. The impact of finite source size on the measurement data, and its correction, are discussed. An expanded discussion of the practical aspects of the tilted-knife-edge test is presented. New chapters are included on speckle-based and transparency-based noise targets, and square-wave and bar-target measurements. A range of practical measurement issues are then considered, including mitigation of source coherence, combining MTF measurements of separate subsystems, quality requirements of auxiliary optics, and low-frequency normalization. Some generic measurementinstrument designs are compared, and the book closes with a brief consideration of MTF impacts of motion, vibration, turbulence, and aerosol scattering.

  • Electricity Network Regulation in the EU: The

    Edward Elgar Publishing Ltd Electricity Network Regulation in the EU: The

    Book SynopsisThe UK model of incentive regulation of power grids was at one time the most advanced, and elements of it were adopted throughout the EU. This model worked well, particularly in the context of limited investment and innovation, a single and strong regulatory authority, and limited coordination between foreign grid operators. This enlightening book demonstrates how the landscape has changed markedly since 2010 and that regulation has had to work hard to catch up and evolve. As the EU enters a wave of investment and an era of new services and innovation, this has created growing tensions between national regulatory authorities in terms of coordinating technical standards and distribution systems. This is being played out against an increasingly disruptive backdrop of digitization, new market platforms and novel business models. Electricity Network Regulation in the EU adopts a truly European approach to the complex issues surrounding the topic, focusing on the grey areas and critical questions that have traditionally been difficult to answer. Incentive regulation and grids are addressed simultaneously at the theoretical and practical level, providing the reader with fundamental concepts and concrete examples. This timely book is an invaluable read for energy practitioners working in utility companies, regulators and other public bodies. It will also appeal to academics involved in the world of electricity regulation. The book utilizes language that would make it suitable for interdisciplinary students, including engineering and law scholars.Contributors include: P. Bhagwat, J.-M. Glachant, S.Y. Hadush, L.

    15 in stock

    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.

    Book SynopsisThe electrochemical storage of energy has become essential in assisting the development of electrical transport and use of renewable energies. French researchers have played a key role in this domain but Asia is currently the market leader. Not wanting to see history repeat itself, France created the research network on electrochemical energy storage (RS2E) in 2011. This book discusses the launch of RS2E, its stakeholders, objectives, and integrated structure that assures a continuum between basic research, technological research and industries. Here, the authors will cover the technological advances as well as the challenges that must still be resolved in the field of electrochemical storage, taking into account sustainable development and the limited time available to us.Table of ContentsINTRODUCTION vii CHAPTER 1.

    Book SynopsisThe electrochemical energy storage is a means to conserve electrical energy in chemical form. This form of storage benefits from the fact that these two energies share the same vector, the electron. This advantage allows us to limit the losses related to the conversion of energy from one form to another. The RS2E focuses its research on rechargeable electrochemical devices (or electrochemical storage) batteries and supercapacitors. The materials used in the electrodes are key components of lithium-ion batteries. Their nature depend battery performance in terms of mass and volume capacity, energy density, power, durability, safety, etc. This book deals with current and future positive and negative electrode materials covering aspects related to research new and better materials for future applications (related to renewable energy storage and transportation in particular), bringing light on the mechanisms of operation, aging and failure.Table of ContentsACKNOWLEDGMENTS vii PREFACE ix INTRODUCTION xi CHAPTER 1.

    Book SynopsisSince the 90s, the Li-ion batteries are the most commonly used energy storage systems. The demand for performance and safety is constantly growing, current commercial batteries based liquid electrolytes or gels may not be able to meet the needs of emerging applications such as for electric and hybrid vehicles and renewable energy storage , and it is therefore necessary to develop advanced storage systems with characteristics such that the highest density of energy technology, long life, low cost of production, little or no maintenance and high safety of use. Batteries "all solid" are a technology of choice to meet these requirements. In this technology, the electrolyte separator between the two electrodes is no longer a liquid medium but a solid.Table of ContentsIntroduction vii Chapter 1 Anatomy of an All-Solid-State Battery 1 1.1 Constituents of an all-solid battery 3 1.1.1 Nature of solid electrolytes: required qualities 3 1.1.2 Positive electrode materials 4 1.1.3 Negative electrode materials 5 1.1.4 Conductive additive 7 1.1.5 Formulation of electrodes 7 1.2 Shaping methods of all-solid batteries 8 1.2.1 Assembly by cold pressing 8 1.2.2 Design by high temperature sintering 10 Chapter 2 Solid Ionic Conductors 13 2.1 Introduction 13 2.2 Solid lithium-ion conductors 15 2.2.1 The Garnets 15 2.2.2 The NASICON AxMM′(XO4)3 Structure 17 2.2.3 The compounds LISICON and Thio-LISICON 18 2.2.4 Ion conductive glass and glass-ceramics 23 2.2.5 The Argyrodites 29 2.2.6 The complex hydrides 34 2.2.7 Phosphorus and lithium oxynitride or LiPON 36 2.2.8 Anti-perovskite lithium-rich solid electrolytes 36 2.2.9 Solid polymer electrolytes 39 2.3 Solid sodium-ion conductors 40 2.3.1 NASICON compounds 41 2.3.2 Na3PS4 42 Chapter 3 All-Solid-State Battery Technology Using Solid Sulfide Electrolytes 47 3.1 Monolithic Li-ion “all-solid-state” batteries 47 3.1.1 The first “all-solid-state” batteries 47 3.1.2 Second generation “all-solid-state” batteries 48 3.1.3 Toward High Performance Batteries 53 3.1.4 Batteries using lithium argyrodite electrolytes 58 3.1.5 Li10XP2S12 (X = Ge, Si, Sn) phase in the structure LGPS 66 3.1.6 Understanding stability at the interfaces between the electrolyte and electrode materials 81 3.1.7 Summary 84 3.2 Sodium monolithic “all-solid-state” batteries 85 3.3 “All-solid-state” Li–S batteries 91 Chapter 4 Monolithic “All-Solid-State” Batteries Using Solid Oxide Electrolytes 97 4.1 Silver “all-solid-state” battery technology 97 4.2 Li-ion “solid-state” battery technology 100 4.3 Sodium “solid-state” battery technology 108 4.3.1 Sodium-ion “solid-state” battery technology 108 4.3.2 Sodium-sulfur “all-solid-state” battery technology 116 Chapter 5 LiBH4 Electrolyte and Polymer Battery Technology 119 5.1 “All-solid-state” battery technology: LiBH4 electrolyte 119 5.2 “Solid-state” polymer battery technology 120 Chapter 6 Markets 123 6.1 Solid electrolytes 123 6.1.1 Ohara 123 6.1.2 NEI 127 6.2 Solid-state batteries 127 6.3 Conclusion 137 Conclusion 139 Bibliography 145 Index 167
