摘  要：该文在交流励磁双馈电机两相同步旋转坐标系的数学模型基础上，利用定子磁场定向控制策略，用Matlab/Simulink仿真软件编写了双馈电机在空载运行和发电运行两个阶段的S函数模型程序，再将这两个阶段的模型整合在一起构建了变速恒频双馈风力发电系统空载并网切入及发电运行的仿真模型，最后在给定风况下进行了仿真，并得到了良好的仿真结果，验证了系统的可靠性。

Abstract: This paper used Matlab/Simulink software to establish S-Functions of no-load operation and generation operation of DFIG with stator flux orientation strategy based on mathematic model of synchronous rotating reference frame of DFIG. The models of two consecutive phases were connected to found a whole VSCF DFIG wind power generation model which was emulated by giving wind to test the right outcome and reliability of the system.
Key words: VSCF; DFIG; stator flux orientation; S-functions; no-load operation; generation operation
