| 摘 要： | 为了分析三峡五级船闸控制系统的可靠性 ,采用了故障树分析法 ,建立了控制系统的故障树模型 ,并对该两冗余系统进行了定性及定量分析 ,由此计算出平均无故障时间 (MTBF)。在此基础上 ,进一步提出了通过增加仿真模型来改进并联冗余结构 ,从而提高了系统决策可靠性

| Abstract: | In this parer,for analyzing reliability of control system of the TGP five step lock,fault tree analysis(FTA) is introduced,and a fault tree model of the control system is established.And the qualitative and quantitative analyses are performed for the two redundant systems,and mean time between fault(MTBF) is calculated.On the basis of the analysis,a method is put forward to improve decision making relability by adding simulation model to parallel connection redundant structure. |
