| 摘 要： | 提出了一种基于粗糙集理论的电力变压器绝缘故障诊断新方法 ,它能够根据不完整征兆信息对电力变压器故障进行诊断。该方法不但可直接从完备的故障征兆样本集中导出正确的诊断结论 ,而且还能从不完备的故障征兆样本集中导出满意的诊断结论 ,它揭示了故障征兆信息的冗余性。实例诊断结果证实了该方法的有效性

| Abstract: | A new method used to identify power transformer insulation malfunction based on rough set theory is proposed.With this method power transformer malfunction can be known based on incomplete symptom information.Not only the accurate diagnosis can be obtained directly from the set of complete fault samples,but also the satisfactory diagnosis results can be got from the set of incomplete fault samples by using this method.The inherent redundancy of the fault information is revealed.The effectiveness of the approach has been verified by the diagnosis results of some examples. |
