The invention discloses a ship electric propulsion system operation protection method and system, and the method comprises the steps: generating a time sequence signal set through a real-time operation data set of a ship electric propulsion system, constructing a plurality of fault monitoring models through an HSMM algorithm, processing different time sequence signals, and enhancing the monitoring capability of the system for multi-dimensional faults; the fuzzy processing is carried out on the system operation state through the membership degree function, effective fuzzy evaluation on the operation state of the ship electric propulsion system can be realized, reasonable judgment and decision can still be made in the face of partial inaccurate or incomplete data, and compared with traditional simple threshold value judgment, the method has the advantages that the judgment accuracy is improved, and the judgment efficiency is improved. The fuzzy rule can make more reasonable judgment in the state transition stage, misjudgment caused by boundary fuzziness is reduced, the fault monitoring accuracy is improved, the most appropriate fault protection scheme can be further matched according to the fault evaluation result, and it is ensured that the ship electric propulsion system is pertinently and effectively protected.

    本发明公开了一种船舶电力推进系统运行保护方法及系统,通过船舶电力推进系统的实时运行数据集生成时间序列信号集,进而通过HSMM算法构建多个故障监测模型,可以分别处理不同的时间序列信号,增强系统对多维度故障的监测能力;通过隶属度函数对系统运行状态进行模糊化处理,能够实现对船舶电力推进系统运行状态的有效模糊评估,使得在面对部分不准确或不完整数据时,依然能够做出合理的判断和决策,相较于传统的简单阈值判定,模糊规则能够在状态过渡阶段做出更为合理的判断,减少由于边界模糊导致的误判,提高故障监测准确性,并进一步根据故障评估结果,能够匹配出最合适的故障保护方案,确保船舶电力推进系统得到针对性、有效的保护。
