摘　　要：柔性直流输电和交流输电是风电场接入的主流方式。基于PSS/E仿真软件及其风力发电软件包,建立了2种不同接入方式下的仿真系统,比较了2种接入方式的优劣。仿真结果证明,柔性直流输电接入方式在系统故障时可向系统提供无功支撑,有利于风电场经受故障,实现不脱网运行。The HVAC （high voltage alternate current） and VSC-HVDC （voltage sourced converters based high voltage direct current） are the two main integration types nowadays. In this paper, the HVAC and VSC-HVDC are compared when they are used as the integration method. The test model is built in the PSS/E and its wind power package. The dynamic response is analyzed and conclusions are drawn. It＇s clear that in the fault situation the VSC-HVDC can supply the power system with reactive power to help recover the wind farm.
