Features: This book is divided into three parts. The relay protection section systematically explains the working principles and wiring of commonly used and basic relay protection devices for transmission lines, generators, transformers, busbars, and motors. The secondary circuit section briefly introduces circuit breaker control, signaling, and synchronization circuits. The automatic equipment section introduces the working principles and composition of devices such as automatic backup power supply, automatic reclosing, automatic excitation regulation, and automatic load reduction based on frequency. This book is a revised version of the 1982 edition. In addition to retaining the original book's clear and accessible style, it has been supplemented and updated to meet the needs of power system development. The content of each chapter has been appropriately strengthened, with a focus on large unit protection, automatic excitation regulation devices, and circuit breaker control circuits. The transistor protection section has been removed, and the concept of integrated circuit protection has been added. Additionally, all graphical symbols and textual symbols in the illustrations in the book have been updated to the new national standards. The content of this book is comprehensive and can serve as a training and self-study textbook for electrical operation and relay protection personnel in power systems. It can also be used as a teaching reference book for relevant majors in secondary vocational schools and technical schools.
