| 摘 要： | 为了提高变压器故障诊断正确率,提出一种免疫支持向量机混合智能诊断方法,首先将变压器故障分为放电性和过热性,然后用免疫聚类算法对所荻取的数据进行预选取,加快模型参数的确定速度,利用支持向量机识别类内变压器故障,利用基于交叉验证的网格搜索法来确定支持向量基的参数.经过大量实例分析,并将其结果与神经网络方法进行对比,表明该算法具有较高的诊断精度.

| Abstract: | In order to improve the correct rate of dissolved gas analysis(DGA),this paper investigates an intelligent mixed method of the artificial immune vector machines,first the transformer faults were divided into two types,discharge fault and thermal fault,the achieved samples were pre-selected with the artificial immune to solve the problem of long time consuming in parameter determination,and the two fault type were recognized with their statistical features.The support vector classifier was adopted to identif... |
