基于关系数据库的变压器故障诊断专家系统

根据油浸式电力变压器的特点及故障诊断的原理,提出了基于关系数据库字段的知识表示形式和基于关系数据库记录的推理规则.特别在推理机方面,根据变压器故障诊断的特点,利用成熟的关系型数据库技术提出一种搜索、替换、构造故障现象与诊断结果对应数据库的推理机制.采用面向对象技术设计开发变压器故障诊断专家系统来解决变压器故障的智能诊断问题,为相关方面故障诊断专家系统的设计开发提供借鉴.

The Expert System of Default Diagnosis of Power Transformer Based on Relational Database

In this paper, the features of fault diagnosis of power transformer are summarized and according to these features, the form of knowledge representation based on the fields and the inference rules based on the records are introduced, according to the characteristics of transformer fault diagnosis, an inference mechanism based on mature relational database is designed to search, replace and construct the tables that correspond the faults to diagnosis. The expert system is developed to resolve the intelligent fault diagnosis of power transformer based on the object-oriented technology.
