【摘要】 本文以模糊数学理论为基础，提出了一个用于高压电力设备故障诊断的专家系统。该系统将专家经验与模糊数学相结合，反映了故障现象与故障原因之间的模糊关系，根据用户输入的故障信息，进行正反向交替的多级推理来作出故障诊断，反映了故障的不确定性，具有较高的诊断可靠性、实用性与通用性强，易于推广。更多还原

【Abstract】 A fuzzy-set-based Expert System(ES) of the fault diagnosis for the high voltage electric power equipments is presented.In the ES,the method of fuzzy theory is combined with the expert experience,and the indeterminate characteristics of the fault is reflected.According to the fault information inputted by user and the progressive forword and backward inferences,the faults of the high voltage electric power equipments are diagnosed.The ES is higher reliability,stronger practicality and generality for the fault diagnosis,and can be popularized easily.更多还原
