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.)
