利用雷电参数划分深圳雷区分布

Lightning Distribution in Shenzhen Region Using Lightning Parameters

根据雷电定位系统记录的深圳地区近8年来雷电活动数据，对深圳地区19992007年的雷电活动日、地闪密度、雷电流幅值等雷电参数进行统计分析，得到各典型雷电参数的分布特征，并绘制了深圳地区雷区分布电子地图。通过与深圳电网110-500kV输电线路多年运行结果进行比较，所绘制的雷区分布图同深圳电网输电线路雷击故障跳闸实际运行经验基本吻合，可用于指导深圳地区新建输电线路防雷设计及已运行线路的防雷改造。

According to the lightning activity data recorded by lightning positioning system （LPS） in Shenzhen, China from 1999 to 2007, lightning parameters such as lightning day, cloud-to-ground （CG） lightning flash density and lightning current amplitude are analyzed utilizing statistical theory. The distribution character of various typical lighting parameters and the electronic map of lightning activity distribution in Shenzhen are obtained based on the statistical analysis results. By comparison with the operation results of 110-500 kV transmission lines of Shenzhen power network in multiple years, it is shown that the electronic map is basically identical to the actual experience of lightning stroke faults of transmission lines in Shenzhen power network, and can be referred while designing the lightning protection ways of transmission lines in Shenzhen.
