基于多源数据融合与设备相似性的高压开关柜评价模型黄俊宁,于群(山东科技大学电气与自动化工程学院,山东青岛266590)摘要:针对目前高压开关柜运行评价大多只是对单一设备进行评价的问题,提出了一种基于多源信息融合,利用设备相似性,使用阈值判断与灰色关联分析的状态评价模型。首先通过带电检测数据、设备信息、设备缺陷三方面,进行多源信息融合并构建开关柜运行状态评价指标体系;然后将三角模糊引入层次分析法,计算指标的权重;考虑到短板效应,引入阈值判断;最后,利用灰色关联分析法,将设备运行环境及状态相近的开关柜进行横向对比及排序,并实现了同时对多台设备的运行趋势分析。通过算例分析,上述方法能更加准确地评估设备的运行状态,为设备检修及维护提供更多的依据。关键词:多源信息;设备相似性;开关柜状态评价;三角模糊数;阈值判断;灰色关联分析EvaluationModelHighVoltageSwitchCabinetBasedonMulti⁃sourceDataFusionandEquipmentSimilarityHUANGJunning,YUQun(CollegeofElectricalandAutomationEngineering,ShandongUniversityofScienceandTechnology,ShandongQingdao266590,China)Abstract:Inviewoftheproblemthattheoperationevaluationofhighvoltageswitchcabinetisonlyforsingleequip⁃mentatpresent,akindofstateevaluationmodelbasedonmulti⁃sourceinformationfusion,theuseofequipmentsimi⁃larity,theuseofthresholdjudgmentandgraycorrelationanalysisisproposed.First,themulti⁃sourceinformationfu⁃sioniscarriedoutandtheoperatingstateevaluationindexsystemofthehighvoltageswitchcabinetisconstructedthroughsuchthreeaspectsaslivedetectiondata,equipmentinformationandequipmentdefects.Then,triangularfuzzinessisintroducedintoanalytichierarchyprocesstocalculatetheweightofindex.Consideringtheshortboardef⁃fect,thethresholdjudgmentisintroduced.Finally,thegrayrelationanalysismethodisusedtocompareandsorttheswitchcabinetswithsimilaroperatingenvironmentandstate,andtheoperationtrendanalysisofmultipleequipmentisachievedsimultaneously.Throughtheanalysisofcalculationexamples,theabovemethodscanmoreaccuratelyevaluatetheoperationstateofequipmentandprovidemorebasisforequipmentoverhaulandmaintenance.Keywords:multi⁃sourceinformation;devi...
