Abstract
换流站无功补偿的研究是特高压直流设计的重要组成部分。本文以哈密–郑州±800 kV直流输电工程为例，按照相应的计算原则计算了不同运行方式下的换流站无功消耗，研究了两端换流站的无功补偿总容量和小组容量要求，在此基础上提出了换流站的无功补偿设备配置方案。 The research on reactive power compensation of converter station is an important component in the design of UHVDC project. Taking ±800 kV DC project from Hami to Zhengzhou for example, the reactive power consumption of converter station under different operating modes is calculated according to corresponding calculation principle. Then the total capacity of reactive power compensation devices of converter stations at both terminals and the group capacity are researched. Based on results of calculation and analysis, a configuration scheme of reactive power compensation devices is proposed.
