摘要：
Performance of electrical equipment is a stochastic process in operation of power system. Maintenance predefined will be invalid if performance of equipment has unexpected changes. In the context of online monitoring, performance states of equipment can be observed all the time. So maintenance can be adjusted with all the performance states of equipment which have unexpected changes. On this basis, a state maintenance decision model of the time-varying performance of the related equipment was established, and the equipment risk and system risk changing with the predetermined maintenance time were given. At the same time, taking the sum of two risks as the goal, and taking into account the related maintenance constraints, the modeling of the state maintenance decision making was completed. Finally, feasibility and validity of the proposed model were analyzed on numerical tests. © 2018 Chin. Soc. for Elec. Eng.
