基于 PSCAD 的双馈风力发电机的仿真建模及特性分析

摘要

应用PSCAD软件建立了转子侧定子磁链定向矢量模型、网侧电压定向矢量模型以及相应的控制模型。针对所搭建的模型，采用渐变风扰动和短路故障两种方式验证其有效性和正确性，结果证明，所搭建的模型顺利实现了最大风能追踪、有功功率和无功功率的解耦，对系统侧扰动也可以实现预期的效果，从而验证了系统的正确性和有效性。%PSCAD is used to build the stator flux directional vector model for the rotor side,voltage directional vector model for the grid side,as well as corresponding control model.The effectiveness and correctness of the models thus built are verified in two methods,namely graded wind disturbance and short-circuit failure.The results prove that the models built can smoothly implement max.wind energy tracking as well as decoupling of active and reactive power.The expected effect on the system side disturbance can also be achieved. Thus,the system correctness and effectiveness are verified.
