基于ATP-EMTP仿真模型的变电站防雷研究

Research on Lightning Protection of Substation Based on ATP-EMTP Simulation Model

本文首先建立500kV变电站在雷电波冲击下的仿真模型,再建立绕击雷电波电源模型。将雷电波电源接于变电站的一条出线,利用ATP-EMTP进行各种情况下的仿真计算,确定作用于各设备的过电压是否超过其过电压耐受水平。

The paper set a simulation model of 500kV substation under lightning wave impact, and then established a lightning strike wave power supply model. The lightning wave power source was connected to one outlet of the substation, and the ATP-EMTP was used for simulation calculation under various conditions to determine whether the overvoltage applied to each device exceeded its overvoltage withstand level.
