摘　　要：本文阐述了舰船电力推进系统故障诊断技术研究的工作,建立了电力推进系统故障诊断基础模型,运用仿真技术为系统设计提供了参考和试验环境,采用神经网络算法获取新知识以提高对未知故障的诊断能力,并设计了基于专家系统的电力推进系统的故障诊断系统,它能使故障诊断更准确和快速。通过故障诊断技术的引入,可以很大程度地提升电力推进系统的可靠性,使系统维修更加方便。It presents our researches on fault diagnosis of naval electric propulsion system at 2009. These studies mainly consist of the creation of fault diagnosis model about key equipment of electric propulsion, failure simulation aimed to providing the test condition to the fault diagnosis system, and ANN algorithm to acquire new diagnosis knowledge in order to increase the ability of diagnosis to unknown failure.The electric propulsion fault diagnosis system based on expert system is designed to make the fault diagnosis more rapidly and exactly. By introducing of above fault diagnosis technique, the reliability and maintainability of the electric propulsion system may be significantly improved.
