变压器故障诊断专家系统的改良设计

介绍了变压器局部放电模型、分类以及局部放电信号在线检测技术,针对变压器局部放电的故障诊断,设计了一种基于模糊推理的变压器局部放电专家系统,该系统建立在传统的专家系统和模糊推理器上。通过仿真实验结果表明,改良后的专家系统对四种典型局部放电信号的识别率有较大提高,为进行局部放电的模式识别提供了一种可靠方法。

Improved Design of Expert System for Transformer Fault Diagnosis

Introduction was made to the model and categories of transformer partial discharge, as well as the online detection technology of partial discharge signals. Aiming at the fault diagnosis of transformer partial discharge, this paper designed a kind of expert system of transformer partial discharge based on fuzzy reasoning. This system was built on the traditional expert systems and fuzzy reasoning unit, The results of simulation experiments show that the improved expert system greatly raised the recognition rate of four typical partial discharge signals, which provides a reliable method for partial discharge pattern recognition.
