First published in 2009. Comprehensive in scope, this book, now in its fully updated second edition, takes an applications-oriented approach to electrical distribution systems. All critical aspects of power production, distribution, control, conversion and measurement are presented. The authors place emphasis on real-world applications, examining electrical distribution and associated system operation from a user's or technician's point of view. The use of an ‘electrical power systems' model facilitates the reader's comprehensive understanding of electrical distribution, utilizing power distribution as a key starting point, and then applying that relationship to other important associated systems. The final chapter of this new edition is re-focused to emphasize the economics of distribution systems, computer power requirements and current environmental considerations. The book provides a valuable desk reference for the working engineer, contractor or technician who needs a thorough application-based guide for finding the best solutions to today's electrical distribution challenges.

This book provides a comprehensive treatment of electric distribution systems. Few books cover specific topics in more depth and there is hardly any book that deals with the key topics of interest to distribution system engineers. The book introduces these topics from two points of view: 1) The practical point of view by providing practical examples and the problems which can be solved. 2) The academic point of view where the analysis and various techniques used for distribution system planning are explained. The most outstanding feature of this book is a combination of practical and academic explanation of its contents. Another outstanding feature is a collection of the traditional and current topics of distribution systems condensed into one book. The reader will gain an understanding of distribution systems from both practical and academic aspects, will be able to outline and design a distribution system for specific loads, cities, zones, etc.. Readers will also be able to recognize the problems which may occur during the operation of distribution systems and be able to propose solutions for these problems.

This study outlines the theoretical and practical aspects which are relevant to the design of distribution networks, particularly the increased use of computers in their design and operation. The edition has been revised to include material on electromagnetic compatibility and legislation.

Power distribution and quality remain the key challenges facing the electric utilities industry. Choosing the right equipment and architecture for a given application means the difference between success and failure. Comprising chapters carefully selected from the best-selling Electric Power Distribution Handbook, Electric Power Distribution Equipment and Systems provides an economical, sharply focused reference on the technologies and infrastructures that enable reliable, efficient distribution of power, from traversing vast distances to local power delivery. The book works inward from broad coverage of overall power systems all the way down to specific equipment application. It begins by laying a foundation in the fundamentals of distribution systems, explaining configurations, substations, loads, and differences between European and US systems. It also includes a look at the development of the field as well as future problems and challenges to overcome. Building on this groundwork, the author elaborates on both overhead and underground distribution networks, including the underlying concepts and practical issues associated with each. Probing deeper into the system, individual chapters explore transformers, voltage regulation, and capacitor application in detail, from basic principles to operational considerations. With clear explanations and detailed information, Electric Power Distribution Equipment and Systems gathers critical concepts, technologies, and applications into a single source that is ideally suited for immediate implementation.

This book highlights the latest research advances in the planning and management of electric distribution networks. It addresses various aspects of distribution network management including planning, operation, customer engagement, and technology accommodation. Given the importance of electric distribution networks in power delivery systems, effectively planning and managing them are vital to satisfying technical, economic, and customer requirements. A new planning and management philosophy, techniques, and methods are essential to handling uncertainties associated with the integration of renewable-based distributed generation, demand forecast, and customer needs. This book covers topics on managing the capacity of distribution networks, while also addressing the future needs of electric systems. The efficient and economical operation of distribution networks is an essential aspect of ensuring the effective use of resources. Accordingly, this book addresses operation and control approaches and techniques suitable for future distribution networks.

Implementing the automation of electric distribution networks, from simple remote control to the application of software-based decision tools, requires many considerations, such as assessing costs, selecting the control infrastructure type and automation level, deciding on the ambition level, and justifying the solution through a business case. Control and Automation of Electric Power Distribution Systems addresses all of these issues to aid you in resolving automation problems and improving the management of your distribution network. Bringing together automation concepts as they apply to utility distribution systems, this volume presents the theoretical and practical details of a control and automation solution for the entire distribution system of substations and feeders. The fundamentals of this solution include depth of control, boundaries of control responsibility, stages of automation, automation intensity levels, and automated device preparedness. To meet specific performance goals, the authors discuss distribution planning, performance calculations, and protection to facilitate the selection of the primary device, associated secondary control, and fault indicators. The book also provides two case studies that illustrate the business case for distribution automation (DA) and methods for calculating benefits, including the assessment of crew time savings. As utilities strive for better economies, DA, along with other tools described in this volume, help to achieve improved management of the distribution network. Using Control and Automation of Electric Power Distribution Systems, you can embark on the automation solution best suited for your needs.
