摘要
在本研究中,提出了一种基于张量块匹配的配电柜非侵入式温升故障识别方法。通过两阶段数据修复重建温度场信息,实现非侵入式配电柜温升故障识别。在粗修复阶段,该方法基于配电柜的外部温度数据,使用张量块匹配技术在温度场张量字典中搜索合适的张量块,从外到内填充目标空间区域,实现了配电柜内部三维温度场的重建。在精修复阶段,利用张量超分辨率技术对粗修复得到的温度场进行填充,实现配电柜内部温度场信息的平滑处理。非侵入式温升故障识别是通过设置聚类规则和温度阈值来比较热源的位置和配电柜组件的位置来实现的。仿真结果表明,与传统技术相比,本文温度场重构误差降低了82.42%,温升故障识别准确率大于86%,验证了温度场重构和温升故障诊断的可行性和有效性。
