基于灰靶理论的高压绝缘子污秽状态综合评判

针对绝缘子污秽程度状态综合评判中没有标准的评估等级划分方法的现状,提出了一种方法对绝缘子污秽状态等级进行划分并对绝缘子污秽等级进行综合评判.将灰靶理论引入到绝缘子污秽状态评估中,结合反映绝缘子污秽状态的相关指标因素,综合考虑各指标的均衡性,构建了绝缘子污秽状态综合评判体系,利用灰靶理论对绝缘子污秽状态等级进行划分,充分...

Synthetic Evaluation of High Voltage Insulator Pollution State Based on Grey Target Theory

According to the existing problem that there is no standard method of evaluation classification method in insulator pollution state synthetic evaluation,a new method that can classify the state of insulator pollution and carried out the synthetic evaluation on the classes of insulator pollution is proposed.Grey target theory is introduced into insulator pollution state synthetic evaluation combining with related factors of insulators’ state,the balance of evaluation index is considered comprehensively,the insulator state comprehensive evaluation system is built,the insulator pollution classes is devided by grey target theory.Combining with expert experience and target information adequately,subjective weight and objective weight are obtained by analytic hierarchy process and entropy method,and finally the approaching degree between each sample to be evaluated and standard sample is calculated,comprehensive evaluation model of insulator pollution state is established.The practical calculation examples show that the proposed method turned to be objective and reasonable evaluation result,the superiority and the efficiency of this model has proved.
