| 摘 要： | 介绍了一种在PSCAD/EMTDC环境中建立双馈风电机组模型以用于电磁暂态分析的方法。分析了风力机风速与输出转矩的关系,建立了机侧换流器的定子磁链定向矢量控制模型、网侧换流器的电网电压定向矢量控制模型,并考虑了低电压穿越控制策略。最后在PSCAD/EMTDC环境中建立了双馈风电机组的模型,仿真验证了建模方法的有效性和正确性。仿真结果表明,在PSCAD/EMTDC环境中,双馈风机建模方法能够准确地描述风电机组的电磁暂态特性。

| Abstract: | This paper outlines a method of modeling doubly-fed induction generators using PSCAD/EMTDC for electromagnetic transient study.First,relationship between wind velocity and output torque of wind turbines is analyzed;then,stator-flux-oriented vector control of machine-side voltage source converter are modeled,so are the grid-voltage-oriented vector control of grid-side voltage source converter;low voltage ride-through method is given too.Finally,model of doubly-fed wind turbine generator is established in PSCAD/EMTDC and.The simulation which is undertakesn to validate the modeling method.Results shows that the proposed method of modeling DFIG using PSCAD/EMTDC can accurately describe electromagnetic transient characteristics of wind generators. |
