风电潮流的波动会引起并网系统公共连接点（PCC）电压的波动。在基于电压源换流

器的高压直流输电（VSC-HVDC）交直流混合风电场并网系统中，控制VSC-HVDC 送端站注入

到PCC 点的无功功率可以抑制电压波动。本文讨论了VSC-HVDC 的无功功率控制器和定电压控制

器抑制电压波动的原理。基于电磁暂态软件PSCAD/EMTDC 建立了并网风电场模型、VSC-HVDC

模型及控制系统模型。仿真结果表明VSC-HVDC 采用定电压控制器的并网系统能更好的抑制电

压波动，采用无功功率控制器的系统具有较好的风电场并网性能。-Reactive power variation of integration wind farm may cause point of common

coupling （PCC） voltage fluctuation. In hybrid wind farm integration system based on HVDC of

voltage source converter （VSC-HVDC）, the voltage fluctuation can be alleviated by compensating

reactive power to PCC from VSC-HVDC sending end. Therefore, the reactive power controller and the

stable voltage controller to alleviate voltage fluctuation are studied in the paper. The integration wind

farm, VSC-HVDC and their controller models are set up by PSCAD/EMTDC. The simulation results

show that the integration system adopted stable voltage controller has a better performance to alleviate

voltage fluctuation. However the system adopted reactive controller has a good wind farm integration

capability.
