| 摘 要： | 由于风机空气动力的不确定性和电机模型的复杂性,双馈风力发电系统的模型很难精确。目前很多控制方法依靠系统和电机的精确模型,这样它们的控制效果就受到很大影响。因此,采用自抗扰控制器进行变速恒频风力发电控制以期提高系统的控制效果。通过定子磁场定向和矢量变化理论,推导出了双馈电机矢量模型和控制策略。采用MATLAB/Simulink建立了系统模型并进行了仿真,仿真结果表明,采用二阶自抗扰控制器在并网后功率解耦控制中具有很好的鲁棒性和抗干扰能力。

| Abstract: | Because of the uncertainty of aerodynamics theory of the wind turbine and complicacy of the generator model,it is difficult to ascertain the model of double-fed induction generation system exactly.However many control method depend on the parameters of generator and system.The control effect is influenced by the variation of the doubly-fed generator’s parameters.Therefore,the active disturbance rejection control(ADRC) is used to control the doubly-fed wind-power system in order to improve the control effect in the dissertation.By using the field oriented control(FOC) method and vector transformation method,the mathematical model of doubly-fed induction generator and the control law of power decoupling deduced and analyzed.The simulation model is built by using MATLAB/simulink to simulate.The simulation results showed that two-order ADRC has good robustness and disturbance rejection capability,during the active power and reactive power decoupling control after synchronization. |
