摘要
为实现双馈风力发电机的变速恒频运行和最大风能捕获,首先介绍了双馈发电机变速恒频运行的原理,其次通过对双馈发电机动态数学模型的研究,提出了基于定子磁场定向的矢量控制策略。最后对系统进行了有功和无功功率独立调节的仿真实验,仿真结果验证了变速恒频双馈风力发电系统建模及控制的正确性和有效性。
In order to implement the control of variable speed constant frequency （VSCF） and maximal wind energy capturing, first the principle of VSCF was introduced, then the strategy of stator-flux-oriented control was presented by analyzing the mathematical model of the doubly fed induction generator （DFIG）. Finally, the simulation of independently modulation of the active and reactive power was done. The result of the simulation verifies the validity and correctness of modeling and control of VSCF doubly fed induction generator.
