摘　　要：维持换流站无功平衡是直流控制保护系统的重要功能,也是确保电网安全稳定运行的重要手段。根据直流换流站无功需求的特点,结合送受端交流系统,对换流站无功平衡及补偿方案进行了分析,探讨了换流站的无功补偿设备总容量及其分组配置方案,归纳了同塔双回直流无功控制系统所面临的主要问题,并提出了相应的解决方案。It is an important function of direct current control and protection system to keep reactive power balance of con- vertor station and meanwhile an important way to ensure safe and stable operation of power grid. According to characteristic of reactive power requirements of DC convertor station and combining with sending and receiving ends alternative current system, this paper analyzes reactive power balance and compensation scheme for the convertor station and discusses total ca- pacity of reactive power compensation devices and cluster configuration scheme. In addition, it summarizes main problems faced for double circuits on the same tower DC reactive power control system and proposes corresponding solutions.
