Power System Relaying [Books and Reports]

This book is primarily intended to be a textbook on protection, suitable for final year undergraduate students wishing to specialize in the field of electric power engineering. It is assumed that the student is familiar with techniques of power system analysis, such as three-phase systems, symmetrical components, short-circuit calculations, load flow, and transients in power systems. The reader is also assumed to be familiar with calculus, matrix algebra, and Laplace and Fourier transforms and Fourier series. Typically, this is the background of a student who is taking power option courses at a U.S. university. The book is also suitable for a first year graduate course in power system engineering. An important part of the book is the large number of examples and problems included in each chapter. Some of the problems are decidedly difficult. However, no problems are unrealistic, and, difficult or not, the aim is always to educate the reader, help the student realize that many o f the problems that will be faced in practice will require careful analysis, consideration, and some approximations. The book is not a reference book, although it may be of interest to practicing relay engineers as well. The book offers derivations of several important results, which are normally taken for granted in many relaying textbooks. By studying the theory behind these results, students may gain an insight
