Power System Relaying, 2/E

The first edition of this book has been used as a text book by universities and in industry courses throughout the world. In this second edition, the theory and fundamentals of relaying, explained in clear, easily understood language, still constitute the major part of the book. In addition, there is much new material, including a chapter on monitoring power system performance and fault analysis. The authors have extensively revised and updated the material from the first edition. Numerical examples, which clarify the text and demonstrate the philosophy underlying relay selection and settings, are included, and problems world-wide are discussed. Contrasts are made between the different technologies and preferences of USA, Europe and Asia.

The previous two editions of Power System Relaying offer comprehensive and accessible coverage of the theory and fundamentals of relaying and have been widely adopted on university and industry courses worldwide. With the third edition, the authors have added new and detailed descriptions of power system phenomena such as stability, system-wide protection concepts and discussion of historic outages. Power System Relaying, 3rd Edition continues its role as an outstanding textbook on power system protection for senior and graduate students in the field of electric power engineering and a reference book for practising relay engineers, and publishes in tandem with Arun Phadke being awarded the Benjamin Franklin Medal from the Franklin Institute in honor of his work in the field of electrical engineering.

• Provides the student with an understanding of power system protection principles and an insight into the phenomena involved.
• Discusses in detail the emerging technologies of adaptive relaying, hidden failures, wide area measurement, global positioning satellites and the specific application of digital devices.
• Includes relay designs such as electromechanical, solid-state and digital relays to illustrate the advantages and disadvantages of each.
• Re-examines traditional equipment protection practices to include new concepts such as transmission line differential protection, load encroachment on distance relay characteristics, distributed generation systems, and techniques to improve protection system response to power system events.
• Analyzes system performance through oscillographs and alarms schemes.
• Features problems to be worked through at the end of each chapter.
