将500kV变电站和进线段结合起来，考虑远近区杆塔冲击接地电阻、雷击点与变电站的距离等影响因素，采用ATPDraw对500kV变电站的雷电侵入波过电压进行了仿真研究。研究表明，近区杆塔接地电阻、雷击点对雷电过电压的大小有较大的影响；当设备过电压较严重时，母线上增装一组避雷器能有效降低过电压；最后，提出在主变避雷器前串联电感，并联电容以抑制雷电侵入波的陡度。
將500kV變電站和進線段結閤起來，攷慮遠近區桿塔遲擊接地電阻、雷擊點與變電站的距離等影響因素，採用ATPDraw對500kV變電站的雷電侵入波過電壓進行瞭倣真研究。研究錶明，近區桿塔接地電阻、雷擊點對雷電過電壓的大小有較大的影響；噹設備過電壓較嚴重時，母線上增裝一組避雷器能有效降低過電壓；最後，提齣在主變避雷器前串聯電感，併聯電容以抑製雷電侵入波的陡度。

The 500 kV substation and the segments are combined, considering the distance zone of tower impulse grounding resistance, lightning and substation distance, influence factors, using ATP Draw for 500 kV substation lightning intruding over-voltage simulation research. Research shows that, near the tower grounding resistance, lightning strike of lightning over-voltage size has bigger effect; when the device over-voltage more serious, bus is additionally arranged on a group of lightning arrester can effectively reduce the over-voltage; finally, put forward the main transformer arrester before the series inductance, capacitance in parallel to suppress lightning invasion wave the steepness.
