摘　　要：列举了直流输电系统换流站的4种接地方式,并对每种接地方式造成的交流侧绝缘影响、换流站内过电压及短路电流水平、电网侧电压暂降进行分析。在此基础上,结合舟山电网特点和舟山多端柔性直流输电运行方式,推荐适合舟山电网的多端柔性直流输电接地方案。The paper enumerates four grounding modes for converter station of DC transmission system and analyzes insulating effects to AC side due to each mode , over-voltage and short circuit current level in the converter station and voltage sag at power system side. On this basis , the paper recommends grounding mode suitable for Zhoushan multi-terminal flexible DC transmission by combining characteristics of Zhoushan power grid and operating mode of Zhoushan multi-terminal flexible DC transmission.
