摘　　要：高压直流换流站无功补偿是高压直流输电工程设计的重要内容,从换流站无功补偿装置和换流站无功调节与控制两个方面介绍高压直流输电换流站无功配置的方法,并从稳态和动态的角度分析了各种无功配置方法的性能。总结了并联型无功补偿装置及串联型无功补偿装置的原理、特点和应用,简述了利用交流系统无功支持能力和变压器抽头调节及触发角调节无功。确定了换流站无功补偿应选择合理的无功补偿装置并充分利用交流系统的无功支持能力和高压直流系统调节综合控制换流站无功。The reactive power compensation of converter station plays an important role in the design of HVDC pro- ject. Reactive power configuration for HVDC converter station is introduced in this paper from two aspects ： the reac- tive power compensation device and the reactive power regulation and control of converter station; the performance of various reactive power configuration methods is compared and analyzed from the aspect of both steady state and dy- namic state. The principle, characteristics and application of shunt and series reactive power compensation device are summarized. The reactive power can be regulated by AC system reactive power support capacity, and by adjusting transformer tap changer and firing angle. It is concluded that proper devices should be chosen carefully for converter station reactive power compensation, and that AC system reactive support capacity and HVDC system regulation must be fully utilized for the comprehensive control over converter station reactive power.
