摘　　要：将变流器用受控源进行等效简化。根据低电压穿越过程中直驱风电机组的动态特性,忽略低电压穿越过程中发电机与机侧变流器的动态过程,建立了适用于暂态电压稳定性研究的简化仿真模型。仿真结果表明,简化模型与电磁暂态模型动态响应一致,可以用于大规模风电场暂态电压稳定性研究。The converters were equivalently simplified into controlled sources. The dynamic process of generators and generator side converter was ignored based on the dynamic characteristics of the D-PMSG in low voltage ride through（LVRT） process. And a simplified simulation model suitable for transient voltage stability research was established. The simulation results showed that the simplified model has the same dynamic response characteristics with the electromagnetic transient model, and it could be applied in the transient voltage stability research in large- scale wind farms.
