摘　　要：根据双馈异步发电机的运行特点,采用定子磁链定向的矢量控制技术,结合滑模变结构控制技术,提出了一种新的转子励磁控制策略。利用Matlab软件建立了双馈异步发电机的仿真模型,对有功无功功率的解耦进行了仿真研究,仿真结果表明,该控制策略能够实现双馈发电机有功功率、无功功率的独立解耦控制。According to the characteristic of double-fed induction generator,a new control method for rotor excitation is established at the stator flux linkage orientation.Variable structure control technology is introduced into modulate of rotor side converter to predigest control system.The simulation platform,which is base on Matlab is established.It can be concluded that the stator flux-oriented vector control strategy can control active and reactive power of double-fed induction generator decoupled respectively.
