| 摘 要： | 高可靠性微机继电保护装置的人为失效、软件失效以及不同检修模式等因素造成的失效不可忽略。同时,其失效率在全寿命周期内并非恒定。针对上述问题,分别建立了考虑多重因素的单个保护装置5状态Markov模型和双重化保护的14状态Markov模型。考虑时变失效因素与检修因素,并对部分检修与全部检修进行区分,比较相应的时变不可用率变化,并给出最优检修策略。

| Abstract: | For the highly reliable protective relay, the software failures, human errors and other failure factors cannot be ignored. Meanwhile, these failure rates are just time-varying in the whole lifecycle. To solve these problems, a 5-state Markov model for single protective relay considering multi-factors and a 14-state Markov model for dual protective relays are developed, respectively. Based on the time-varying failure rate and maintenance factors and by referring to the current maintenance strategies of the State Grid, the time-varying unavailability of partial maintenance is distinguished from that of complete maintenance under different maintenance strategies, with the optimal maintenance strategy given.
