摘　　要：根据双馈异步发电机的运行特点，推导出了其在静止参考坐标系中的数学模型，采用定子磁链定向的矢量控制技术，并结合滞环电流控制技术，提出了一种新的转子励磁控制策略。利用Matlab仿真软件建立双馈异步发电机的仿真模型，对有功和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和无功功率的独立解耦控制。According to the characteristics of the Doubly-fed induction generator, the mathematical model of DFIM in stationary reference frame was deduced, and thus, a new control strategy for rotor excitation is proposed by using the vector control technology of the stator flux linkage-oriented, combined with the hysteresis current control technology. With the aid of the Matlab simulation software, a simulation model of the double-fed induction generator is built to do simulation research on the decoupling control of active power and reactive power respectively. The simulation result indicates that the control strategy can realize the independent decoupling control for active power and reactive power of the double-fed induction generator.
