摘　　要：阐述针对现有监测方法在对高压单芯电缆故障监测时,无法确定护层单相接地故障具体位置的问题。结合高压单芯电缆的运行特点,构建高压单芯电缆护层单相接地感应电压模型,辨识故障发生后测量数据中存在的不良数据,并将其剔除。结合混沌粒子群算法,通过迭代寻找全局最优粒子,实现对单芯电缆护层单相接地故障的定位,完成自动监测。This paper expounds the problem of existing monitoring methods being unable to determine the specific location of single-phase grounding faults in the protective layer when monitoring high-voltage single core cable faults.It combines the operating characteristics of high-voltage single core cables to construct a single-phase grounding induced voltage model for the protective layer of high-voltage single core cables,identifies and eliminates any defective data in the measurement data after a fault occurs.It combines the chaotic particle swarm algorithm to iteratively find the global optimal particle,achieving the localization of single-phase grounding faults in single core cable protective layers and completing automatic monitoring.
