摘　　要：运用故障树分析方法，对核电站全厂断电事故进行分析。建造了全厂断电事故即厂用电力系统Ａ、Ｂ两列６．６ｋＶ交流应急母线ＬＨＡ和ＬＨＢ同时失电故障树。利用ＳＥＴＳ程序及法国标准９０万千瓦压水堆核电站２００堆年运行经验反馈的可靠性数据，对全厂断电故障树作了定性、定量分析，得到了全厂断电事故的发生概率。给出了全厂断电事故的主要失效模式及发生的概率和事件的重要度。The failure modes for station blackout of nuclear power plant were studied based on the system fault tree approach. The top event in the station blackout fault tree was defined as the simultaneous power supply failure of both engineered safeguard buses LHA and LHB. Based on the component failure rates of the standard French 900MWe pressurized water reactor, the frequency of station blackout was evaluated using SETS code, with the dominant failure modes and component importances analyzed and interpreted.
