基于三角均分模糊推理的电力设备故障诊断

Fault Diagnosis of Electric Power Equipments Using TPE Fuzzy Inference

电力设备的故障诊断具有不确定性．应用三角均分模糊推理系统能够利用实际故障诊断数据，吸收专家诊断经验，获取与完备故障诊断规则知识。

It is very difficult to acquire the knowledge for the fault diagnosis of the electric power equipments because of the fuzzy and the stochastic uncertainty of the failure mechanism and the inadequacy of the failure data.By the Triangular Partition fuzzy inference system with the midpoints of the triangular fuzzy subsets evenly spaced on the normalized domains(TPE systems),the fuzzy rule knowledge for the fault diagnosis can be acquired from the practical date and expert experience of the fault diagnosis,and completed based on philosophy of analogy and similarity.By this method,the fuzzy expert system for the fault diagnosis of the electric power equipments can be developed successively.
