| 摘 要： | 将５００ｋＶ变电站和进线段结合起来，考虑绝缘子串冲击伏秒特性、进线段冲击电晕和杆塔冲击接地电阻等影响因素，分远区及近区落雷，采用国际通用的电磁暂态计算程序（ＥＭＴＰ）对５００ｋＶ变电站的雷电侵入滤过电压进行了研究。研究表明将５００ｋＶ变电站和进线段结合起来更接近实际情况进线段诸因素对变电侵入波过电压的大小有较大影响。

| Abstract: | The study on overvoltage for 500 kV substation caused by lightning intruded wave is presented. In this paper, we calculate by using electromagnetic transient program (EMTP) and combine substation with incoming lines ,so some influence factors can be considered such as impulse voltage second characteristic of insulator strings, lightning stroke point on the incoming lines and impulse grounding resistance of towers. The results show that the method is close to the practice and some factors of incoming lines are important to overvoltage. |

| Keywords: | lightning overvoltage insulator strings / substation incoming lines impulse voltage second characteristic |
