本文分析了汽轮发电机常见故障的特性,并绘制了故障树,介绍了一种新开发的故障诊断专家系统。该系统根据在数据库中贮存的症状和在知识库中贮存的专门知识,研究所有的故障树,计算每一故障的概率,给出推理过程,并提出在某种情况下应采取何种措施的建议。该系统还具有趋向分析和预测功能。 This paper analyzes the common fault characteristics of turbogenerators, and draws a fault tree, introduces a newly developed fault diagnosis expert system. The system studies all the fault trees based on the symptoms stored in the database and the expertise stored in the knowledge base, calculates the probability of each failure, gives the reasoning process, and proposes what measures should be taken in certain circumstances Suggest. The system also features trend analysis and forecasting.
