Along with rapid development of power technology, the old primary equipment in many substations is in the urgent needs of replacement. As a major primary equipment, the breaker plays an important role in stable operation of a substation. The traditional breaker replacement method has a time-consuming problem, affecting the power supply reliability. The breaker replacement method for 110 kV substations is optimized in this paper by using the key route method. It is proved that the optimized new method can significantly shorten the replacement time and reduce the power cut time of a transmission line, subsequently improving the stability of electric power system and the reliability of power supply.
