Power System Protective Relaying

This book focuses on protective relaying, which is an indispensable part of electrical power systems. The recent advancements in protective relaying are being dictated by MMPRs (microprocessor-based multifunction relays). The text covers smart grids, integration of wind and solar generation, microgrids, and MMPRs as the driving aspects of innovations in protective relaying. Topics such as cybersecurity and instrument transformers are also explored. Many case studies and practical examples are included to emphasize real-world applications.

Dr. J.C. Das is currently the President of Power System Studies, Inc. Snellville, USA. He headed the Electrical Power Systems Analysis Department at AMEC Inc., (now AMEC Foster Wheeler, Inc.) Tucker, GA, USA, for the last 30 years. He has varied experience in the utility industry, industrial establishments, hydroelectric generation, and atomic energy. He is responsible for power system studies, including short-circuit, load flow, harmonics, stability, arc-flash hazard, grounding, switching transients, EMTP simulations, and protective relaying. He conducts courses for continuing education in power systems and has authored or coauthored approximately 65 technical publications, six textbooks, and over 7,000 total published pages.
