Digital protection is based on the use of computers in power line relaying. This book gives a detailed understanding of the principles and techniques underlying the application of digital technology and algorithms to protection.

Digital power system protection, as a subject, offers the use of computers in power line relaying which is the act of automatically controlling the power system via instrumentation and control devices. This book is an attempt to make a gentle introduction to the nitty-gritty of digital relays. Written in a simple, clear and student-friendly style, this text covers basics of digital processing of analog signals for the purpose of relaying. All important basic algorithms that are used in various types of digital relays have been explained. FIR and IIR filters have been presented in such a manner that students will be able to develop intuitive understanding. The book also covers DFT and FFT and synchrophasor technology in details. MATLAB programs and Excel simulations have been given to reinforce the comprehension of the algorithms. This book has been thoroughly class-room tested and based on course notes which is primarily intended for undergraduate and postgraduate students of electrical engineering. Key Features • In-depth coverage of DSP fundamentals • Pedagogical tools like figures, flowcharts, block diagrams and tables have been extensively used • Review questions are given at the end of each chapter • Extensive references to literature on power system protection

Digital Signal Processing in Power System Protection and Control bridges the gap between the theory of protection and control and the practical applications of protection equipment. Understanding how protection functions is crucial not only for equipment developers and manufacturers, but also for their users who need to install, set and operate the protection devices in an appropriate manner. After introductory chapters related to protection technology and functions, Digital Signal Processing in Power System Protection and Control presents the digital algorithms for signal filtering, followed by measurement algorithms of the most commonly-used protection criteria values and decision-making methods in protective relays. A large part of the book is devoted to the basic theory and applications of artificial intelligence techniques for protection and control. Fuzzy logic based schemes, artificial neural networks, expert systems and genetic algorithms with their advantages and drawbacks are discussed. AI techniques are compared and it is also shown how they can be combined to eliminate the disadvantages and magnify the useful features of particular techniques. The information provided in Digital Signal Processing in Power System Protection and Control can be useful for protection engineers working in utilities at various levels of the electricity network, as well as for students of electrical engineering, especially electrical power engineering. It may also be helpful for other readers who want to get acquainted with and to apply the filtering, measuring and decision-making algorithms for purposes other than protection and control, everywhere fast and on-line signal analysis is needed for proper functioning of the apparatus.

Part of a series that summarizes the concepts, practices and equipment used in the field of power system protection, this volume explores recent advances in digital technology, digital signal processing, communications, numeric protection and co-ordinated control systems.

Power System Control and Protection focuses on the control and protection of power systems to ensure a secure and reliable supply as the society depends greatly on electric energy. This book examines the problems surrounding the generation, transmission, distribution, and utilization of electricity. Comprised of 10 chapters, this book starts with an overview of the functional and environmental requirements for the intelligent remote terminal in which much of the logic linked with each function has been programmed and is executed in a digital processor. This text then examines the objectives, functions, and elements of the control center design. Other chapters consider the operating characteristics and configuration of the system components of an audio-frequency power line carrier load management system. This book discusses as well the concept of transmission line relaying by digital computer. The final chapter deals with the large-scale utilization of wind energy. Power systems engineers will find this book useful.

Protection of Modern Power Systems Familiarize yourself with the cutting edge of power system protection technology All electrical systems are vulnerable to faults, whether produced by damaged equipment or the cumulative breakdown of insulation. Protection from these faults is therefore an essential part of electrical engineering, and the various forms of protection that have developed constitute a central component of any course of study related to power systems. Particularly in recent decades, however, the demands of decarbonization and reduced dependency on fossil fuels have driven innovation in the field of power systems. With new systems and paradigms come new kinds of faults and new protection needs, which promise to place power systems protection once again at the forefront of research and development. Protection of Modern Power Systems offers the first classroom-ready textbook to fully incorporate developments in renewable energy and ‘smart’ power systems into its overview of the field. It begins with a comprehensive guide to the principles of power system protection, before surveying the systems and equipment used in modern protection schemes, and finally discussing new and emerging protection paradigms. It promises to become the standard text in power system protection classrooms. Protection of Modern Power Systems readers will also find: Treatment of the new faults and protection paradigms produced by the introduction of new renewable generators Discussion of SmartGrids—intelligently-controlled active systems designed to integrate renewable energy into the power system—and their protection needs Detailed exploration of Synchronized Measurement Technology and Intelligent Electronic Devices Accompanying website to include Solutions Manual for instructors Protection of Modern Power Systems is an essential resource for students, researchers, and system engineers looking for a working knowledge of this critical subject.

Electrical Power System Protection provides practising engineers with the most up-to-date and comprehensive one -volume reference and tutorial on power system protection available. Concentrating on fundamental methods and technology and with extensive examples drawn from current practice internationally, this book will be a major reference tool for engineers involved with and affected by power system protection.
