20231期基于AHP-EW的变压器健康状态画像研究*张立柱,高慧,张林峰,李雅文,武同宝(国网泰安供电公司,山东泰安271000)摘要:由于变压器内部结构复杂,涉及数据海量、价值密度低及状态评价主观臆断性强,使得变压器的使用门槛较高,维护过程中也较难对其精准定位,因此为方便设备管理人员及时掌握变压器的健康状态,构建了一套变压器状态评价指标体系,并采用层次分析法和熵权法确定指标综合权重,使得画像结果更客观、可靠,完成变压器定期检修到状态检修的转变,为电力运维人员提供较好的指导作用。关键词:配电变压器;评价指标体系;层次分析法;熵权法;健康状态画像中图分类号:TM73DOI:10.19768/j.cnki.dgjs.2023.01.016ResearchonTransformerHealthStatePortraitBasedonAHP-EW*ZHANGLizhu,GAOHui,ZHANGLinfeng,LIYawen,WUTongbao(StateGridTaianElectricPowerCompany,Taian271000,China)Abstract:Duetothecomplexinternalstructureofthetransformer,involvingmassivedata,lowvaluedensityandstrongsubjectiveassumptionofstateevaluation,theusethresholdofpowerpractitionersishigh,anditisdifficulttoaccuratelylocateitinthemaintenanceprocess.Therefore,inordertofacilitatetheequipmentmanagerstograspthehealthstateofthetransformerintime,asetoftransformerstateevaluationindexsystemisconstructed.Then,theanalytichierarchymethodandtheentropyweightmethodareusedtodeterminethecomprehensiveweightoftheindex,sothattheportraitresult...
