摘要

船舶电力系统为自发电、自分配的独立电力系统,当电力设备出现故障时,会影响船舶的航行安全。为了对船舶电力设备故障信号进行准确的诊断,依据故障计算原理,利用故障并行计算方法进行船舶电力设备故障信号诊断,仿真试验证明,并行计算方法的故障诊断正确率与所耗时间均优于对比算法,同时,随着参与并行计算的线程的增加,诊断的实时性随之增强,是一种高效的船舶电力设备故障诊断方法。
        Ship power system is a self-generating and self-allocating independent power system. When power equipment fails, it will affect the safety of navigation. In order to accurately diagnose the fault signal of marine electric power equipment, according to the principle of fault calculation, the parallel fault calculation method is used to diagnose the fault signal of marine electric power equipment. The simulation results show that the correctness rate and the time consumed by the parallel calculation method are better than the contrast algorithm. At the same time, with the participation of the parallel calculation method, the fault diagnosis of marine electric power equipment is carried out. With the increase of the calculation line, the real-time performance of the diagnosis is enhanced. It is an efficient fault diagnosis method for marine power equipment.
