摘　　要：针对船舶电力系统内部组成复杂,可靠性定量评估工作量巨大且容易出错的问题,论文以某工程船直流低压系统为目标系统,通过对目标系统的故障树模型建立,依据蒙特卡洛仿真原理完成对目标系统可靠性特征的仿真计算。仿真结果显示,此方法所得数据精度高,参数分布曲线直观明了,对于船舶电力系统可靠性的有效评估具有十分重要的意义。Aiming at the problem of complicated internal composition of Marine power system reliability quantitative evalua⁃tion work is huge and error prone.This paper takes the DC-low voltage system of an engineering ship as the target system,builds the fault tree model of the target system,and completes the simulation calculation of the reliability characteristics of the target sys⁃tem according to the Monte Carlo simulation principle.The simulation results show that the data obtained by this method is highly ac⁃curate and the parameter distribution curve is straightforward,which is of great significance for the effective evaluation of the reli⁃ability of marine power system.
