【Abstract】 Taking 110 kV substation as an example, this paper designs the health status index evaluation and maintenance system of secondary equipment in substation. Starting with the construction and analysis of the health model of secondary equipment, this paper introduces the structure and construction method of the health model of secondary equipment. Then, the selection method of secondary equipment condition evaluation index is expounded, and the index weight of secondary equipment condition evaluation model is determined by analytic hierarchy process(AHP). Based on the analytic hierarchy process method, the state of secondary equipment is evaluated, and the realization path of on-line monitoring system of secondary equipment in substation is given. The system is used to monitor the operation status of secondary equipment in real time, and to continuously evaluate the availability, safety and performance of secondary equipment. Finally, the actual operation effect of the system is analyzed. It is verified that the system can find the fault of secondary equipment in time, which is conducive to ensuring the safe and stable operation of all equipment in the substation.更多还原
