摘要:

首先选取14个复合绝缘子老化评估指标,进行整理分类,构建两层评估体系。然后对评估指标进行归一化处理并选定隶属函数,由改进层次分析法计算得出常权,引入基于均衡函数的变权模式,对常权重进行修正得到变权,从而建立复合绝缘子老化状态模糊综合评估方法。最后,基于老化评估模型,结合试验数据对所提方法的可行性进行了实例验证。验证表明,所提评估方法较常权评估模型更能够真实客观反映复合绝缘子的老化状态,对于指导复合绝缘子的检修与更换具有借鉴的意义。

Abstract:

The aging indexes of composite insulators are sorted out,and two layers of evaluation index system are constructed,with 14 evaluation indexes selected.Through the normalization of evaluation indexes and the selection of membership functions,on the basis of the constant weight determined by the improved analytic hierarchy process,the variable weight mode based on the equilibrium function is introduced,and the constant weight is modified to obtain the variable weight,so as to establish the fuzzy synthetic evaluation method for aging state of composite insulators.Finally,the aging model is verified by the experimental data of composite insulators.The results show that the fuzzy synthetic evaluation model based on the variable weight theory can reflect the aging state of insulators objectively.The method has a reference for the maintenance and replacement of composite insulators.

Key words: composite insulators, aging state, improved analytic hierarchy process(IAHP), fuzzy synthetic evaluation, experimental data
