Electronic and electrical technology plays a very important role in the power system, which is helpful to improve the operation efficiency of the power system and make the power engineering construction in China develop better. Therefore, the technical personnel of relevant scientific departments should strengthen the research of electronic and electrical technology, so as to optimize the operation of electrical system in China and improve the application level of electronic and electrical technology in power system. On this basis, this paper discusses the application of electronic technology in power system for reference.展开更多
