【摘要】 在作者提出的电力变压器绝缘故障诊断概率模型的基础上 ,文章又以统计数据为依托来考察故障与征兆之间的相互关系 ,以及故障发生的可能性的同时 ,考虑了在征兆提取中的模糊边界问题。与仅用概率推理或模糊数学的方法相比 ,文中的方法更能真实地反映故障诊断的特性更多还原

【Abstract】 The parsimonious covering theory integrated with probability and fuzzy technique is applied to analyze power transformer malfunctions. The relationship between malfunction and symptom along with the possibility of malfunction are realized, as well as fuzzy borderline is considered at extracting symptoms. Test results show that the model has better performance than using probability or fuzzy reasoning individually.更多还原
