| 摘 要： | 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.

| Abstract: | 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. |
