Features: This book primarily discusses the working principles, electrical connections, operational analysis, usage methods, and basic calibration calculations of commonly used relay protection and automatic devices in thermal power plants. It also introduces some new relay protection principles in combination with field conditions. The book is divided into two parts. Part 1 is on Relay Protection, which is divided into six chapters covering current protection for interphase short circuits in power grids, longitudinal differential protection for transmission lines, protection for power transformers, protection for synchronous generators, busbar protection, and motor protection. Part 2 is on Automatic Devices, which is divided into three chapters covering automatic backup power supply systems, automatic excitation regulation devices for synchronous generators, and automatic synchronization devices for synchronous generators. To facilitate teaching and self-study, each chapter includes review questions. This book is primarily intended as a training textbook for advanced technicians in electrical technology in thermal power plants, providing professional theoretical knowledge for technicians seeking to apply for the title of technician in power plant operation, maintenance, and testing. It can also be used as a reference for engineering technicians in related fields and adult education instructors.
