Power Sytem Protection

Power System Protection by P.M. Anderson This is an academic book on power system protection. It was prepared to serve as an introductory text in power system protection for graduate students in Electric Power Systems. The present edition is the out growth of previous editions that have been used by several universities for 25 years. There is a fundamental problem in developing a graduate course in power system protection at a university. Most faculty members are not experts at relaying, and very few practice this art on a regular basis. With out consistent contact with the field, it is difficult to keep up-to-date, particularly with respect to new relay hardware. But there is a more fundamental problem in this regard. One has to question whether the teaching of protection hardware and relay settings is appropriate material for academic study.Analysis is one subject that the university professor can teach with authority, and is one that many practicing engineers need to understand more thoroughly. Therefore, it is hoped that this book will be of value to both the graduate student and the practicing protection engineer.The author taught this subject for many years and shared his notes with professors from other universities. The comments were gratifying, and encouraged the development of a full textbook on the subject of system protection. There is no doubt that protection is one of the most demanding technical subjects in power systems, and protection engineers are a breed apart. The author shares an intense interest.in the subject with these masters of the art and science of protection. Most of the engineers who practice power system protection learn this craft by practical application-the author included. There is an opportunity,however, for the academic pursuit of protection as a science in its own right. Therefore, I hope this book assists those who make this study their life's work-a noble pursuit and one that enthusiastically recommend.
