Features: This book is a work covering the principles of relay protection in high-voltage power systems. It uses clear language to illustrate the profound basic ideas and fundamental principles of relay protection, with detailed derivations for the analysis of various relays. It serves as both a theoretical monograph and a textbook. The book discusses the analysis methods and characteristics of short-circuit faults, open-circuit faults, and composite faults in power systems. It provides a detailed discussion and analysis of the phasor diagram method for distance relays, systematically analyzing and discussing the basic concepts, working principles, analysis methods, and performance characteristics of impedance relays, distance relays, and frequencyvariable relays. These issues form the theoretical foundation of relay protection in high-voltage power grids. The book is divided into six chapters: Chapter 1 Introduction, Chapter 2 Power System Fault Analysis, Chapter 3 Voltage Phasor Diagrams for Relay Protection, Chapter 4 Impedance Relays, Chapter 5 Distance Relays, Chapter 6 FrequencyVariable Measurement Principles. This book is suitable for relay protection professionals with a foundation in relay protection theory, as well as for use as a selective textbook and reference book for undergraduate and graduate students in higher education institutions.
