摘要

提出了一种基于粗糙集的理论对变压器故障性质和故障部位的综合诊断方法。它既充分利用了油中溶解气体的分析结果

又考虑了一些比较典型的影响因素

如某些电气试验结果和其它试验结果。由于利用了粗糙集理论的决策表约简技术

去除冗余信息

大大压缩了人工神经元网络（ANN）的训练样本

从而有效地提高了ANN的训练速度和诊断的准确率。

Abstract

A synthetic fault dia gnosis method based on RS theory for electric power transformer fault character and fault location is proposed.Both the DGA analysis results and some other typi cal factors such as electrical test results are fully considered.The training st ylebook of ANN is compressed and the redundancy information is deleted by using decision table reduction technique of RS

thus the training speed and the accurac y of diagnosis are effectively improved.
