摘　　要：鉴于平波电抗器不同布置方式会影响换流站内一次设备的雷电过电压耐受水平,采用EMTP/ATP电磁暂态仿真软件,建立±800kV典型换流站直流侧雷电侵入波过电压计算模型,计算了高压极母线和中性线母线上平波电抗器不同布置方式下站内设备的反击耐雷水平。结果表明,部分布置方式可以显著降低换流站高压极线侧单台平波电抗器两侧过电压最大值,这对提高平波电抗器运行可靠性和增加绝缘裕度具有一定的参考价值。The arrangement of different number of smoothing reactor （SR） on each bus of the converter station will affect the flashover lightning performance of the station equipment. In this paper, a typical transmission model of the DC side of the ~800 kV converter station was built via the EMTP/ATP software, which was used to calculate the lightning protection performance of baek-flashover for the station equipment under different arrangement of SR on the high voltage bus and neutral-bus. Simulation results show that some kind of arrangement of the SR can significantly reduce the maxi- mum voltage between the two sides of one SR on the polar side, which has a certain reference value to improve its opera- tion reliability and increase its insulation margin.
