| 摘 要： | 将系统可靠性分析方法GO法与Markov法相结合,对核电厂概率安全分析(PSA)中厂外电源丧失(LOOP)后柴油发电机应急响应系统在24h内缓解全厂断电(SBO)事件中的动态过程进行分析,解决了维修相关存在下可修系统可靠性精确计算问题,并通过创建GO法“备用门”操作符真实地模拟应急响应系统工作的逻辑关系.通过将2种可靠性分析方法相结合使用的尝试,使之与柴油发电机应急响应系统存在维修相关的实际情况相适应,拓展了2种方法的分析领域,同时能够更为精确地得出SBO对系统安全运行的影响. |

| Abstract: | Based on the GO methodology and Markov method,the dynamic analysis of emergency die-sel generator system for protecting the nuclear power plant from Station Blackout,which is caused by Loss of Offsite Power event,is made with duration of 24 hours.In addition,the accurate reliability calculation problem is solved for the repairable system with dependant maintenance relation,and the logic relation of emergency response system is fully simulated by creating the "Backup Operator" of the GO methodology.By combining the two reliability analysis methods,which is used suitably for the emergency response system of diesel generators with dependant maintenance relation,the application range for the two methods is expanded,and the effect of station blackout event on the safety operation of nuclear power plants can be obtained more accurately. |
