摘　　要：提出了基于动态泄荷电阻的柔性直流输电的故障穿越控制方案,详细分析了泄荷电阻的阻值设计和动态控制。为了验证控制方案的有效性,在PSCAD/EMTDC中建立了双馈感应风电机组经VSC-HVDC联入交流电网的仿真模型。并验证了仿真模型的有效性,为后续进一步验证交流电网故障期间,泄荷电阻工作时该控制策略的有效性和实用性奠定基础。In this paper, based on dynamic dissipation resistance,it is proposed the fault through control scheme in the flexible HVDC, analyzing in detail the design and dynamic control of the dissipation resistance. In order to verify the va- lidity of the control strategy, it is established double-fed induction wind turbines linked to grid by VSC-HVDC simulation model in PSCAD/EMTDC. And based on verifying the model, during the grid fault, with dissipation resistance working, verifv the validitv and practicability of the strategy.
