计及健康评估与风险量化的变压器检修策略张安安，刘自强，李茜，杨威，蒲彩霞（西南石油大学电气信息学院，四川成都610500）摘要：为量化检修对变压器健康状况与运行风险的影响，本文中作者提出了一种计及健康评估与风险量化的变压器检修策略制定方法。首先，建立变压器健康评估指标体系，基于健康评估构建表征变压器实时健康状况的可靠性模型；其次，采用恢复函数量化不同检修方式对变压器可靠性的影响，通过等效役龄法确定检修前后的变压器可靠性；然后，分析变压器的运行风险经济，构建合理的检修策略优化模型；最后，采用改进鸽群算法进行迭代寻优，从而确定最优检修方案及检修时间。通过对某变电站变压器的检修策略分析，验证了所提方法的可靠性与准确性。关键词：变压器；可靠性；运行风险；检修策略中图分类号：TM407文献标识码：B文章编号：1001－8425（2023）03－0029－07TransformerMaintenanceStrategyConsideringHealthAssessmentandRiskQuantificationZHANGAn-an,LIUZi-qiang,LIQian,YANGWei,PUCai-xia（SouthwestPetroleumUniversity,Schoolofelectricalinformation,Chengdu610500,China）Abstract：Toquantifytheimpactofmaintenanceontransformerhealthstatusandopera-tionrisk,thispaperproposedatransformermaintenancestrategyformulationmethodconsideringhealthassessmentandriskquantification.Firstly,thetransformerhealtheval-uationindexsystemisestablished,andthereliabilitymodelrepresentingthereal-timehealthstatusoftransformerisconstructedbasedonthehealthevaluation;Secondly,therecoveryfunctionisusedtoquantifytheinfluenceofdifferentmaintenancemethodsontransformerreliability,andthetransformerreliabilitybeforeandaftermaintenanceisde-terminedbyequivalentserviceagemethod;Then,theoperationriskeconomyoftrans-formerisanalyzed,andareasonablemaintenancestrategyoptimizationmodeliscon-structed;Finally,theimprovedpigeonswarmalgorithmisusedforiterativeoptimizationtodeterminetheoptimalmaintenanceschemeandmaintenancetime.Thereliabilityandaccuracyoftheproposedmethodareverifiedbyanalyzingthemaintenancestrategyofatransformerinasubstation.Keywords：Transformer；Reliability；Operationalrisk；Maintenancestrategy1引言变压器作为电力系统的关键电气设备之一，其健康状况...
