| 摘 要： | 将电力变压器故障历史数据首先进行模糊化及离散化处理,然后构建故障诊断决策表,以决策表作为主要工具,即"知识库",采用粗糙集数据挖掘方法直接从决策表中提取出潜在的诊断规则,为电力变压器提供有效的故障诊断.

| Abstract: | In this paper,the history fault data of power transformer is processed with fuzzy and scatter method.The processed data is used to structure the fault diagnosis decision-making table which is treated as ("knowledge database").This paper introduced rough sets data mining method to take potential diagnosis rule from the fault diagnosis decision-making table of power transformer.These rules can offer effective fault diagnosis service for power transformer. |
