输电网络设备故障诊断专家系统的设计与实现

Design and Realization of Malfunction Diagnosis Expert System for Power Transmission Network Facility

介绍一套输电网络设备故障诊断专家系统的设计结构,确定诊断系统由故障巡检和故障诊断专家系统组成。在故障诊断的方法中引入了故障树分析,同时将领域专家的经验知识转化为诊断系统的知识,构建采用正向推理机制的诊断系统。

The design composition of malfuction diagnosis expert system of the power transmission network facility is introduced, and it is determined that the diagnosis system is composed of malfuction inspection and malfuction diagnosis expert system. The analysis method of malfuction tree is imported into the method of malfuction diagnosis and accordingly the field expert knowledge is converted into expert system diagnosis knowledge. A diagnosis system with forward reasoning mechanism is also constructed.
