故障并行计算在船舶电力设备故障信号诊断中的应用

Application of fault parallel computing in fault diagnosis of marine power equipment

诊断船舶电力设备故障信号对于船舶安全航行有重要意义,传统的计算方式采用独立计算的方法,工作量大,准确性差。针对上述问题,研究了一种新的计算方式——故障并行计算,对其在船舶电力设备故障信号诊断中的应用作了具体研究。计算过程从平行运行和斜向运行两方面考虑,工作流程分为故障机理确定、电力设备状态监测、故障征兆提取、故障诊断和决策判断五步。与传统方法做出实验对比,结果可知,故障并行计算工作量小,准确性高,在诊断船舶电力设备故障信号中发挥着关键性的作用。

It is very important to diagnose the fault signal of ship's electric power equipment for safe navigation. The traditional calculation method uses independent calculation method, which has heavy workload and poor accuracy. In view of the above problems, a new calculation method, fault parallel computing, is studied, and its application in fault signal diagnosis of marine electric power equipment is studied in detail. Considering the parallel operation and oblique operation, the calculation process is divided into five steps: fault mechanism determination, power equipment condition monitoring, fault symptom extraction, fault diagnosis and decision-making. Comparing with the traditional method, the results show that the parallel fault calculation has the advantages of small workload and high accuracy, and plays a key role in diagnosing the fault signal of marine power equipment.
