Features: This book primarily introduces the composition and principles of microprocessor-based relay protection devices. The content is divided into eight chapters.
Chapter 1 introduces the development history and characteristics of microprocessor-based protection.
Chapter 2 introduces the working principles of the two commonly used data acquisition systems in microprocessor-based protection.
Chapter 3 briefly introduces the hardware composition and basic circuit principles of microprocessor-based protection.
Chapter 4 introduces the design and implementation methods of digital filters.
Chapter 5 introduces various algorithms applied in microprocessor-based protection devices.
Chapter 6 introduces high-frequency protection, distance protection, and zero-sequence current direction protection for transmission lines.
Chapter 7 introduces the microprocessor-based protection principles for generators and transformers. It focuses on the ratio protection for generators and transformers, methods for identifying inrush currents, stator grounding protection for generators, and generator loss-of-field protection.
Chapter 8 briefly introduces the hardware and software anti-interference technologies of microprocessor-based protection.
This book can serve as a textbook or teaching reference for undergraduate and graduate students in power system and automation-related fields at universities. It can also be used as a reference for engineering technicians engaged in microprocessor-based relay protection.
