摘要
结合风力发电系统的特点 ,从瞬时有功功率的角度出发 ,给出了新的双馈电机力矩的控制方法。在控制中只需检测交流侧电流电压 ,不需要位置传感器 ,控制算法当中以计算简单的转子感应电势观测器代替了磁通观测器。最后 。
A novel control strategy of the doubly fed induction machine using speed sensorless scheme was proposed.The proposed control method uses only the rotor voltages and currents as the feedback signals,which substantially reduces the costs and enhances the reliability of the speed sensorless control of a DFIM. And the field observer is replaced by a simpler induction potential observer. Experimental result is given to verify the speed senseless control scheme.
