摘要考虑到风力发电机系统当中风轮机的转动惯量较大,不要求快速的动态响应。该文针对双馈发电机提出了一种结合稳态的分析与瞬时采样定向和控制的方法,称为准稳态转子感应电势定向的控制方法。在转子感应电势的定向当中使用了线性相位有限长脉冲响应数字滤波器,在控制中只需要检测转于侧电流电压,构成了结构简单的无速度传感器双馈电机的控制系统。实验验证了该方法的正确性和实用性。 Considering the huge moment of inertia of the wind turbine, it has no request for fast response. A novel control strategy of the DFIM is proposed, which is defined by the author quasi-stable state rotor EMF orientated vector control. The method combined the stable state analysis with the transient control. The linear phase response FIR is used in the rotor EMF orientation. Compared to the other position senseless schemes for winding induction machine, the proposed control method uses only the rotor voltage and current as the feedback signals, which substantially reduces the costs and enhances the reliability of the position senseless control of the winding induction machine. Experimental results are given to verify the position senseless control scheme.
