摘　　要：以往的功率电气设备电磁噪声污染防治效果评价方法由于仅从单一的角度筛选出防治效果评价指标,导致方法的评价效果不佳。因此,设计了功率电气设备电磁噪声污染防治效果评价方法。利用传感器获取相关运行状态数据,从中筛选出防治效果评价指标,并归一化处理,再计算评价指标客观权重值和主观权重值,利用构建的判断矩阵对其进行一致性判断,由此构建电磁噪声污染防治效果评价模型,实现对电磁噪声污染防治效果的评价。在实验测试中,设计的方法在实际应用中电磁噪声抑制率平均在95%以上,评价效果更好。In the past,the evaluation method of electromagnetic noise pollution prevention and control effect of power electrical equipment only screened out the evaluation index of prevention and control effect from a single angle,which led to poor evaluation effect.Therefore,the evaluation method of electromagnetic noise pollution prevention effect of power electrical equipment is designed.Sensor is used to obtain the relevant operation state data,from which the evaluation index of prevention and control effect is selected and normalized,and then the objective weight and subjective weight of the evaluation index are calculated.The consistency of the evaluation index is judged by using the constructed judgment matrix,thus the evaluation model of prevention and control effect of electromagnetic noise pollution is constructed,and the evaluation of prevention and control effect of electromagnetic noise pollution is realized.In the experimental test,the electromagnetic noise suppression rate of the designed method is above 95%on average in practical application,and the evaluation effect is better.
