| 摘 要： | 鉴于电力变压器故障信息具有不完备性及复杂性，将不完备信息系统规则的提取与Petri Nets(PNs)有机结合在一起进行变压器故障诊断。利用不完备信息规则提取对信息表进行知识的简化与故障特征的压缩，获得最小诊断规则，并利用此规则建造PNs的模型。同时利用PNs实现并行推理，对变压器进行快速分析。故障实例分析表明，文中所提出的智能方法具有准确性，有效性。

| Abstract: | Due to the incompleteness and complexity of fault information for power transformer,based on complementary strategy,rule extration in incomplete information system and Petri nets(PNs) are integrated for synthetic fault diagnosis of transformer in this paper.Through rule extraction reducing information knowledge and fault symptoms,table to simplify the minimal diagnostic rules can be mined,then based on this rules,the Petri nets are built.Meanwhile,parallel reasoning can be used to analyze the transformers f... |
