摘要
提出一种基于故障诊断的船舶电力系统状态评估方法,将故障模式及影响分析和3σ统计原理应用到系统状态评估中,建立了从监测参数到故障诊断,从而得到即时状态的评估模型,并对船舶电力系统的实际运行状态做出了评估.计算结果表明,模型评估过程简单、清晰,评估结论准确、有效.
A state assessment method of the ship electrical power system is provided, which is based on the fault diagnosis. The failure mode effect analysis and 3σ statistical theory are carried into the evaluating mode, from which the instant state can be obtained An example of electric power system is applied to calculate its instant-state by using the evaluation model. It has been found that the model is with simple evaluating procession, adequate theory and valid conclusion.
