纯电动船舶动力系统故障模式与影响分析

Failure mode effects analysis on power system of battery-powered ship

为提高纯电动船舶动力系统的可靠性,本文以纯电池动力船舶典型动力系统为对象,进行了动力系统故障模式与影响分析(FEMA),分析了控制电源、控制系统、主回路电气故障发生时动力系统以及船舶的状态变化,厘清了不同故障类型、不同故障点对船舶动力系统的影响,对纯电池动力船舶的设计具有较强参考意义。

In order to improve the reliability of the all electric marine power system,this paper conducts a power system failure mode and effect analysis(FEMA)for a typical battery-powered marine power system,analyzes the state changes of the power system and the ship when the control power supply,control system,or the main circuit electrical faults occur,and clarifies the effects of different fault types and different fault points on the marine power system.The analysis has a strong reference significance for the design of battery-powered ships.
