本发明公开种直流换流站，涉及直流输电领域，能够降低直流换流站在运行过程中所带来的最大地电位升，缓解直流换流站对周围环境所造成的侵扰。具体方案为：所述直流换流站连接第接地极，其中所述第接地极为配置给所述直流换流站的接地极；所述直流换流站还连接有至少个第二接地极，其中所述第二接地极为配置给其它直流换流站的接地极，其中每个所述直流换流站配置个对应的接地极；所述直流换流站在运行过程中通过所述第接地极和所述至少个第二接地极向大地放电。本发明用于直流输电系统内直流换流站的部署连接。 The invention discloses a DC converter station, and relates to the field of DC transmission. The maximum grounding potential rise caused by the DC converter station in the operation process can be reduced; and intrusion of the DC converter station to the surroundings is relieved. According to the specific scheme, the DC converter station is connected with a first grounding electrode; the first grounding electrode is the grounding electrode configured for the DC converter station; the DC converter station is also connected with at least one second grounding electrode; the second grounding electrode is the grounding electrode configured for the other DC converter stations; one corresponding grounding electrode is configured on each DC converter station; and the DC converter sta
