摘要：针对传统的跟踪发电电压的标量控制策略控制无刷双馈电机的并网运行时存在的问题，提出一种跟踪电网电压矢量定向控制的无刷双馈电机的并网运行控制方法，同时在无刷双馈发电系统输出端与电网之间引入一个缓冲电抗器，使无刷双馈电机发电电压矢量、电网电压矢量和电抗器两端电压矢量构成一个矢量三角形，从而实现了无刷双馈电机的发电并网运行。实验结果验证了本文提出方法的有效性。

Abstract: In order to improve the operating performance of doublyfed induction generation system, this paper proposed a direct power control (DPC) based on backstepping algorithm. First established the mathematical model of the doublyfed induction generator based on stator flux orientation control, then combining backstepping control and direct power, begin from achieving power tracking, backstepping controller was designed. In the Matlab/Simulink environment, the system was simulated. The simulation results show that the designed controller can achieve wind power system active power and reactive power tracking, and has good dynamic and static performance and robustness.
Key words: doubly fed wind power generation; backstepping algorithm; direct power
