Abstract:

以往的雷电预警研究无法给出特定区域落雷密度以及落雷频数随着雷暴生消演变的规律,而这是影响输电线路实时雷击跳闸概率的关键因素,对于输电线路雷击跳闸预警研究具有重要意义。首先将观测的目标区域按0.01°×0.01°划分为等面积网格,将每15min雷电定位系统测量落雷数据按时间等分为3段;通过对每段落雷数据聚类分析剔除数据中的杂散点;在聚类云团识别的基础上,线性拟合3个连续时间段每个聚类云团质心位置,预测未来15min内任意时间聚类云团质心移动规律;统计分析该时间段每个网格落雷密度并利用反距离加权插值法对所有网格在该时间落雷密度进行计算,获得聚类云团覆盖区域;最后,利用海南电网雷电定位系统历史数据对该算法进行验证。结果表明,该算法在15min内聚类云团质心预测结果相对误差在20%以内,落雷预测区域与实际落雷区域基本吻合。
