针对在用电缆电流谐波检测方法存在的耗时长等不足，提出一种基于电流谐波的多算法评分机制下的电力电缆诊断和寿命分析方法。首先采集目标电缆各次谐波数据，然后基于电缆状态评估专家数据库得出电缆的当前现状，最后将电缆历史数据作为输入量，通过评分机制下表现最优的模型获取电缆的寿命分析结果以及健康度评价。并基于以上分析，搭建电缆诊断和寿命分析管理应用平台，通过在内蒙古电力（集团）有限责任公司某供电分公司的实际应用，验证了所提方法的实用性。
Abstract：In view of the shortcomings of the current harmonic detection method, the author proposes a diagnosis and life analysis method of power cable concerned multi-algorithm scoring mechanism based on current harmonic. First of all, the harmonic data of the target cable is collected, and then the current status of the cable is obtained based on the expert database of cable state evaluation. As the input data, the cable life analysis results and health evaluation are obtained through the model with the best performance under the scoring mechanism. Based on the above analysis, the cable diagnosis and life analysis management platform is established. The application of the platform in a power supply branch of Inner Mongolia Power(Group) Co.,Ltd. verifies the practicability of the proposed method.
