摘　　要：±800kV云广直流工程是世界上第一个±800kV级直流输电工程,换流站的无功补偿与配置方案是特高压直流输电系统设计的重要组成部分。根据特高压换流站无功需求的特点,结合送受端交流系统,对换流站无功补偿与配置进行了研究,提出了换流站的无功补偿设备总容量及其分组配置方案,通过校核计算和换流站无功分组投切的数字仿真,验证了该无功补偿与配置方案的可行性。The±800kV DC power transmission project from Yunnan to Guangdong in China is the first practical ±800 kV DC power transmission engineering home and abroad. Reactive power compensation scheme and its configuration are important components in the design of UHVDC power transmission system. According to the features of reactive power demand of UHVDC converter station and taking UHVAC power system at the sending and receiving ends of the UHVDC transmission line into account, the reactive power compensation for converter station and its configuration are researched, and the total capacity of reactive power compensators for converter station and the scheme of dividing these compensators into groups are proposed. By means of checking calculation and numerical simulation, the proposed reactive power compensation scheme and its configuration are verified.
