摘要

高压并联电抗器故障机理复杂

反映电抗器内绝缘状态信息的数据因子繁多且具有不确定性。为此

结合工程经验建立了指标体系

基于层次分析法建立了高压并联电抗器的绝缘状况评估模型

通过指数标度法确定了各评估指标的权重;然后着重针对油中溶解气体指标

采用模糊综合评判评估了电抗器油中溶解气体状况

在此基础上综合判断了电抗器绝缘状态

并进行了实例验证。结果表明:提出的评估方法能有效判断投运的高压并联电抗器绝缘状况

为高压并联电抗器的检修提供技术依据。

Abstract

The fault mechanism of high voltage shunt reactor is complicated

and the data that reflect the insulation state information in the reactor are various and uncertain.Therefore

the index system is established based on the engineering experience.The method of analytic hierarchy process（AHP） is utilized to establish the evaluation model of insulation of high voltage shunt reactor in this paper.Firstly

the reactor insulation condition assessment index system is established.The index scale process is used to determine the weight of each index

and then the fuzzy comprehensive evaluation is used to assess the condition of oil dissolved gas in the reactor focusing on the dissolved gas index.Finally

the insulation condition of reactor is evaluated.The verification results show that the proposed assessment method can effectively judge the insulation condition of high voltage parallel reactor operation

and can provide the technical basis for the maintenance of high voltage shunt reactors.
