Features: This book is divided into three parts: Relay Protection Principles, Substation Automation Devices, and Relay Protection Operation. Among them, Relay Protection Principles (Chapters 1 to 8) include content such as current protection for interphase short circuits in power grids, directional current protection for interphase short circuits, ground protection for power grids, distance protection for power grids, differential protection for power grids, high-frequency protection for power grids, protection for power equipment and electrical equipment, and the principles of microcomputer relay protection. Substation Automation Devices (Chapter 9) include content such as circuit breaker reclosing devices, automatic backup power supply devices, and automatic load reduction devices based on frequency. Relay Protection Operation (Chapters 10 to 13) include content such as case studies on the configuration of relay protection in power grids, case studies on faults in power grid relay protection, analysis of the operation of power grid relay protection, and new technologies in relay protection. Chapters marked with an asterisk are non-essential parts of classroom teaching and can be used as references for teachers during instruction or for students to read after class. This book can serve as a teaching material for power system automation, power supply and distribution technology, and power consumption management and supervision majors in higher vocational colleges and higher colleges, and can also be referenced by technical personnel engaged in relay protection work in related fields.
