近年来，因雷击引起的电网故障发生率较高，各类防雷装置受成本和保护范围的限制，不可能在线路全线使用。研究了一种基于无线传感器网络的电网雷击实时监测与分析系统，根据线路的具体情况布置无线传感器节点，实时采集前端避雷器状态数据、雷击时的各种实时雷电参数，通过传感器网络多跳传送至主控监测中心，使后方人员能实时了解电网防雷设备的运行状况，及时分析雷击的形式和故障地点，为准确判断输电线路雷害成因提供证据。

In recent years, the power grid failure caused by lightning has kept on a high level. Many kinds of lightning protection device can’t be used in all lines because of the l cost limit and protection scope. Areal-time monitoring and analysis system for grid lightning has been developed based on the wireless sensor network, which could arrange the wireless sensor node according to the line’s conditions,collect real-time status data of front arrester and the parameters of lightning, and sent them to master monitoring center through the multi-jump sensor network. Then the workers can timely master the operation status of grid lightning protection equipments, as well as can analyze the lightning form and fault position, which will provide the powerful evidence for the accurate judgment of lightning disturbance causes to transmission line.
