摘要
为考察低压配电网中变电站雷电侵入波特性,用ATP-EMTP仿真计算了雷击35 kV变电站进线段时站内设备的过电压值。仿真结果表明:随着进线段杆塔高度的增加、冲击接地电阻的增大以及避雷器与被保护设备间距离的增长,设备所遭受的过电压值随之增大。仿真结果可供低压配电网变电站进线段设计参考。
In order to investigate invasion wave performance of substation of low voltage distribution network, the ATP-EMTP simulation program is applied to simulate and analyze the invasion wave overvoltage of substation equipments. The results show that the overvoltage on substation equipments will increase with increases of the pole height, the pole surge ground-resistance in incoming lines and the distance between the position of lightning arrester and substation equipment. The simulation results can be referred when design the incoming lines of the substation of low distribution network.
