摘　　要：构建水轮机导水机构故障诊断系统的目的,是自动诊断得出故障发生的原因。为此,以模糊理论为基础,结合水轮机导水机构的实际运行工况、专家经验等,构建了导水机构故障诊断知识库;分析了故障原因与故障征兆之间的模糊关系,建立了导水机构模糊故障诊断数学模型。用故障诊断实例验证了模糊理论在水轮机导水机构故障诊断中的可行性。This paper point out the aim for constructing fault diagnosis system of gate operating mechanism. On the basis of fuzzy set theory, combining the actual performance of gate operating mechanism and the experts experiences,a knowledge base is established for fault diagnosis.The paper also analyzed the fuzzy relationship between the faults and their portent,and established the mathematic model for fuzzy fault diagnosis system.Finally,the paper gave an example of actual fault dignosis,validating the feasibility of fuzzy theory in the fault diagnosis for gate operating mechanism.
