一种考虑多影响因素的10 kV配电网雷害风险动态评估方法

open access: yesDianci bileiqi
针对现有主网雷害风险评估方法在配电网中适用性不足的问题,提出一种考虑多影响因素的10 kV配电网雷害风险动态评估方法。该方法综合考虑线路参数、建筑物分布、地表水体、土壤类型、雷电地闪密度与雷电流幅值分布等多源因素,建立涵盖直击雷、感应雷及建筑物屏蔽修正的完整雷击闪络率计算体系。引入深度学习语义分割模型,基于高分辨率遥感影像自动提取建筑物轮廓与地表水体信息,实现地理参数的动态更新;结合雷电定位系统数据,动态获取雷电活动参数,支撑区域风险的动态评估。采用1 km×1 km网格划分与极差归一化方法 ...
