船舶电力系统的故障诊断专家系统研究

为了保证船舶电力系统的供电连续性，及最大可能的缩短船舶停电时间，在分析了船舶电力系统故障特点的基础上阐述了基于继电保护信息的船舶电力系统诊断专家系统的设计。根据故障现象的不同将整个诊断系统划分为输电线路诊断和其他设备诊断两个模块。在知识表示上根据船舶电力系统的特点采用了框架与产生式相结合的方式，同时为了处理故障识别过程中的不确定问题，引入了模糊规则。本系统在对哈尔滨工程大学的船舶电力系统仿真装置诊断时，能够正确、快速的得出诊断结论。因此这种船舶电力系统的故障诊断方法是行之有效和值得推广的。

Relay Protection Based Fault Diagnosis of Ship Power Supply System

The design of the expert fault diagnosis system for the ship electrical system is described through analysis of electrical system fault characteristics.The whole diagnosis system consists of two modules: first fault diagnosis and second fault diagnosis.Framework is combined with generation for expression of knowledge,and fuzzy rules are introduced to solve uncertainty issues during recognization and treatment of faults.Simulation results proved the effectiveness of the fault diagnosis system for ship power supply system.
