A New Method of Maintenance and Repair of Secondary System in Intelligent Substation

Abstract

With the improvement of domestic power systemthe demand for electricity in society has been increasing, and the electric power engineering construction projects have gradually increased. With the development of science and technology, intelligent substation is the direction of substation construction at prcsent., intelligent substation as a new trend of future power system development in our country, There are many new technologies involved in intelligent substation, such as digital transformer, network communication, photoele- ctric technology, etc. Its structure and function are different, and making substation sustainable, stable, safe and economical is still the ultimate goal of intelligent substation construction, and how to detect and maintain the secondary equipment system in the intelligent substation has become the fundamental to ensure the normal and stable operation of the intelligent substation. Therefore, intelligent substation relay protection has become an important research subject. This paper expounds the characteristics of intelligent substation and secondary equipment system and the relay protection debugging and application of intelligent substation., and thinks about a new method that can realize the maintenance and repair of secondary equipment system of intelligent substation and hope to be helpful for future intelligent substation project in China.
