摘　　要：通过对发电机绝缘老化机理以及当前绝缘诊断方法的分析 ,提出了分布式绝缘诊断专家系统的思想。该专家系统以局部放电在线监测为基础 ,融合温度和振动传感器的数据 ,采用从局部到整体、从分析到综合的分析思路。整个专家系统的诊断分为局部放电的纵向分析、综合分析、统计分析及离线试验数据分析 4层。Based on the analysis of insulation mechanism and diagnostic methods for generators, a distributed insulation diagnostic expert system (ES) is proposed in this paper. The ES system mainly relies on the data from on-line partial discharge monitoring systems. Other data from temperature and vibration sensors is also used to assist the analysis. An analytical method, which make analysis from part to integer, from analysis to synthesis is adopt in ES construction. The insulation diagnosis is divided into four layers, which are the trend analysis of partial discharge, the synthesis method, the stochastic analysis and the data analysis of off-line test. A blackboard model is used to construct the diagnostic ES.
