电力变压器故障诊断专家系统研制及其应用技术开发

Development of Expert System for Power Transformer Fault Diagnosis and Its Application

电力变压器故障诊断对变压器、电力系统的安全运行有着十分重要的意义。本文介绍了变压器故障诊断的基本原理和常用方法,描述了所开发的TFDES结构、推理机制、特点、实现方法及各模块的功能,并结合具体实例测试表明:TFDES结构合理,推理正确,能有效地诊断运行中变压器的内部潜伏性故障。

Diagnosis of power transformer abnormality is important for power system reliability. The principle and usual methods for transfonner fault diagnosis, and the construction, mechanism and performance of TFDES(an expert system for power transformer fault diagnosis) arc described in this paper. The results of preliminary tests show that the system has reasonable construction and correct inference, and can effectively detect incipient faults of transformers in service.
