| 摘 要： | 在总结领域专家经验基础上,采用模糊诊断方法,列出了仿真系统中变压器的征兆集和故障集,并根据征兆集和故障集的相互关系构建模糊诊断矩阵;通过模糊关系矩阵运算,提出最大隶属度原则判断变压器故障原因。测试和评价结果表明模糊诊断在仿真系统中的有效性和可行性。

| Abstract: | In this thesis we draw fuzzy method into transformer fault diagnosis, and the symptom setting and the fault setting are also listed based on the history data and expert experience. Based on the relationship between the symptom setting and the fault setting, the articme presents the fuzzy correlation matrix. According to the calculation of the fuzzy correlation matrix, the vector of fuzzy fault can be determined by membership grade rule. It is proved that the diagnosis method based on fuzzy theory is feasible and superior through a real example of transformer fault of an actual hydroelectric system. |
