Features: To coincide with the training and assessment activities for relay protection technicians in the national power system from 1997 to 2005 and the actual situation, the State Power Dispatch and Communication Center decided to comprehensively revise and update the book "Practical Technical Questions and Answers on Power System Relay Protection," originally published in May 1997 by more than 20 relay protection experts. This is the revision work for the second edition. This book is the second edition of "Practical Technical Questions and Answers on Power System Relay Protection." Based on the relay protection standards and regulations issued by the Ministry of Power Industry, the State Economic and Trade Commission, the National Development and Reform Commission, the State Power Corporation, the State Grid Corporation, the China Southern Power Grid Corporation, and the top five power generation groups in China, combined with the actual situation of relay protection nationwide, it explains the basic knowledge of power system relay protection, relay protection regulations, current and voltage transformers and phase sequence filters, line protection, busbar protection and circuit breaker failure protection, power transformer protection, generator protection and automatic devices, power system safety automatic devices, electrical secondary circuits, countermeasures against relay protection accidents and anti-interference, and other aspects in the form of Q&A. It is an important book for relay protection professionals to study and improve their technical quality, with a total of 10 chapters and 772 questions. Additionally, the appendix provides the 1997 relay protection professional test and assessment questions and answers, as well as the 2002 power system relay protection professional competition written test questions and answers and supplementary questions. This book is suitable for engineering technicians, workers, and scientific and technical management personnel engaged in relay protection operation, design, research and development, installation, and commissioning in the national power system, as well as relevant professional teachers and students.
