摘　　要：应用故障模式影响分析法(failure mode and effect analysis,FMEA),建立预想事故的FMEA表,是配电网可靠性评估中较为普遍的方法。应用配电网络编码技术,提出了一种FMEA表的计算机自生成方法,实现了不同类型复杂配电网FMEA表的自动建立,从而快速计算配电网的可靠性指标。该方法建立了配电网元件编码信息的筛选规则,通过与故障元件编码的对比,自动判断故障后系统内各组成部分的停电情况,进而遍历所有的预想事故生成FMEA表,用于可靠性评估。该方法考虑了孤岛运行方式下分布式电源的容量约束,能够适用于新能源接入配电网后FMEA表的自生成和可靠性评估。通过算例验证了该方法的有效性。Failure mode and effect analysis（ FM EA） table is a commonly used tool in the reliability evaluation procedure of distribution netw orks. Utilizing the netw ork coding technique,this paper proposed an auto-generation method for FM EA table,w hich could realize the auto-generated FM EA table for complex distribution netw orks w ith different types,and could be used to quickly calculate the reliability indices of distribution netw ork. The proposed method established the filtering rule of netw ork coding information of distribution netw ork element, judged the netw ork outage situation automatically after fault through the comparison w ith fault component coding,and traversed all the possible accidents to form FM EA table for reliability evaluation. With considering the capacity constraints of distributed generation（ DG） under islanded mode,this method also could be applied in the FM EA auto-generation and reliability evaluation for the distribution system w ith new energy. The effectiveness of the proposed method w as verified by a study case.
