变压器故障诊断专家系统的开发及应用

Development and Application of Transformer Fault Diagnosis Expert System

介绍了变压器故障诊断模型的建立、变压器故障诊断专家系统的总体设计、软件功能及其应用情况。该专家系统采用的故障综合诊断技术先进,符合现场使用习惯,可根据故障的性质、严重程度和状态评价结果,给出科学的、符合现场实际的检修决策,实现了故障的不漏判、不错判。该系统为变压器设备的精密点检、状态检修提供了良好的软件平台,为实现变压器合理点检定修、降低发输电成本提供了一种有效手段。

This paper first introduces the establishment of a transformer fault diagnosis model,and then describes the overall design,main functions and business applications of a transformer fault diagnosis expert system.The advanced fault diagnosis techniques exploited in this paper follow practical use habits,and has no missing or wrong judgment during diagnosis process.It can provide rational and realistic maintenance decision based on property,severity and status of the fault.This system provides a good software platform for accurate fault diagnosis and maintenance of transformer equipment,and an effective method to reduce power generation and transmission cost.
