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.


This new edition of a successful reference work provides the professional with all the techniques and methods which are required to be incorporated into the design of an electrical power system. The new edition has been comprehensively updated and contains new chapters on the essential topics of digital communications, digital signal processing and protection and, lastly, new relaying concepts. The book provides a sound and complete treatment of the fundamentals of power system protection and illustrates the principles with examples from current practice. The text includes many insights into modern technologies and research areas. Electrical Power System Protection is an essential reference handbook for all engineers working in electrical utilities, as well as for designers and users of electrical protection equipment. It also forms a complete reference text for advanced undergraduate and postgraduate students on courses in electrical engineering.
