With emphasis on power system protection from the network operator perspective, this classic textbook explains the fundamentals of relaying and power system phenomena including stability, protection and reliability. The fourth edition brings coverage up-to-date with important advancements in protective relaying due to significant changes in the conventional electric power system that will integrate renewable forms of energy and, in some countries, adoption of the Smart Grid initiative. New features of the Fourth Edition include: an entirely new chapter on protection considerations for renewable energy sources, looking at grid interconnection techniques, codes, protection considerations and practices. new concepts in power system protection such as Wide Area Measurement Systems (WAMS) and system integrity protection (SIPS) -how to use WAMS for protection, and SIPS and control with WAMS. phasor measurement units (PMU), transmission line current differential, high voltage dead tank circuit breakers, and relays for multi-terminal lines. revisions to the Bus Protection Guide IEEE C37.234 (2009) and to the sections on additional protective requirements and restoration. Used by universities and industry courses throughout the world, Power System Relaying is an essential text for graduate students in electric power engineering and a reference for practising relay and protection engineers who want to be kept up to date with the latest advances in the industry.

Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers The function of the CT is to reproduce in its secondary winding a current I’ that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0–5 ampere range for convenience of measurement. The function of the relay is to discriminate between normal operation and fault conditions. The OC relay in Figure 2 has an operating coil, which is connected to the CT secondary winding, and a set of contacts. When |I’| exceeds a specified ‘‘pickup’’ value, the operating coil causes the normally open contacts to close. When the relay contacts close, the trip coil of the circuit breaker is energized, which then causes the circuit breaker to open. System-protection components have the following design criteria: · Reliability: Operate dependably when fault conditions occur, even after remaining idle for months or years. Failure to do so may result in costly damages. · Selectivity: Avoid unnecessary, false trips. · Speed: Operate rapidly to minimize fault duration and equipment damage. Any intentional time delays should be precise. · Economy: Provide maximum protection at minimum cost. · Simplicity: Minimize protection equipment and circuitry. Since it is impossible to satisfy all these criteria simultaneously, compromises must be made in system protection. The book consists from the following sections: 1. Chapter 1: Power System Faults: 2. Chapter 2: Instrument Transformers. 3. Chapter 3: Overcurrent and Earth Fault Protection Relays. 4. Chapter 4: Radial System Protection. 5. Chapter 5: Zones of Protection. 6. Chapter 6: Differential Relays. 7. Chapter 7: Distance Relays. 8. Chapter 8: Transformer Protection. 9. Chapter 9: Generator Protection. 10. Chapter 10: Busbar Protection. 11. Chapter 11: Circuit Breakers. 12. Chapter 12: Fuses. 13. Chapter 13: References.

The death of Professor Arthur Wright in the summer of 1996 deprived me of a friend and a colleague whose judgement and experience shaped this book. I pay tribute to his contributions to protection and electrical engineering education. In the five years since the first edition appeared, many developments have taken place and it is now necessary to update the book. The use of digital communications and advanced signal processing techniques is now widespread and several fully numeric relays are available from manu facturers. Two new Chapters 13 and 14 have been added to introduce readers to these concepts and associated techniques. Artificial intelligence is making its impact in all engineering applications and power system protection is no exception. Expert systems, fuzzy logic, artificial neural networks, adaptive and integrated protection, synchronized measurements using the global positioning system, genetic algorithms, flexible a.c. transmission systems, are some of the techniques considered in connection with protection. Although many of these techniques have not yet found major application in protection, it is nevertheless essential for the educated protection engineer to have a basic understanding of the underlying principles and methodology so that he, or she, can evaluate their suitability for new relaying problems and applications. Chapter 15 was therefore added to guide readers through this developing area. I have also added some new material in other chapters to reflect changes over the past years.

The power utilities industry is going through a period of massive re-organization worldwide. The delayering brought about by an attempt to reduce costs and therefore provide cheaper power to the consumer means that many non-specialist engineers and technicians are now responsible for the power protection systems.This book originated from a successful course initiated by the skills shortage and the pressure of the Occupational Health & Safety Act and Risk Management. It is a practical introduction to basic fundamentals of power system protection, e.g., safety measures to control the impact of large voltage surges, for example a bolt of lightning or a short circuit. It is not a theoretical text but is designed to demystify the subject in order to allow non-specialists to implement safely power protection systems.
