    摘 要:針對保護或斷路器出現(xiàn)拒動條件下,保護期望動作狀態(tài)計算結(jié)果與實際動作邏輯間可能出現(xiàn)失配的原因進行了分析。通過計及主保護、近后備保護、遠后備保護和斷路器失靈保護間相互制約關(guān)系,給出了一種電網(wǎng)故障診斷模型解析規(guī)則的改進方法。仿真算例表明,所提方法能夠提高故障診斷模型目標函數(shù)的計算精度,獲得更加合理的故障診斷結(jié)果。

    Abstract: In allusion to the occurrence of misoperation in protective relays and circuit breakers, this paper analyzed the cause that the calculating results of expected action state mismatched the actual operation results of protective relays. By considering the mutual interaction relationship among main protection, near backup protection, far backup protection and circuit breakers failure protection, this paper gave the amended analytical rules of a kind of grid fault diagnosis model. Simulation examples show the proposed method may improve the calculation accuracy of object functions of fault diagnosis models, and thus obtain more reasonable fault diagnosis results.
    Key words: fault diagnosis; analytical model; protection relay; alarm information; power system
