Features: This book is a national planning textbook for secondary vocational education. It is divided into 13 units, with main content including: current protection for power grids, distance protection for power grids, full-line fast protection for transmission lines, automatic reclosing of transmission lines, relay protection for power transformers, relay protection for generators, busbar protection, microcomputer-based relay protection, automatic backup power supply devices, automatic frequency reduction load devices, automatic synchronization devices for synchronous generators, automatic excitation regulation devices for synchronous generators, and fault recording devices. This book covers both relay protection and automatic devices in power systems. With the widespread adoption of microcomputer-based relay protection devices and microcomputer-based automatic devices today, it is entirely feasible to combine the originally separate relay protection and automatic devices into one. This is because their input signal preprocessing and hardware circuits are largely the same, and combining them reduces unnecessary duplication. Additionally, it aligns with the trend of power plants and substations moving toward comprehensive automation. Below each unit title, there is a content summary for that unit, followed by a unit summary and review questions. This book can serve as a textbook for electrical-related majors in various secondary vocational education programs and can also be referenced by engineering technicians working in the fields of relay protection and automatic devices.
