摘要

本文研究了定子电流反馈控制双馈飞轮发电机直流磁通偏差问题。连接到转子的PWM逆变器的交流输出电压会在定子中产生直流磁通偏差。从定子电流和/或电压中检测直流磁通是困难的，因为直流磁通不会对定子绕组产生电动势。本文提出了一种通过计算定子和转子电流的磁化电流来抑制直流磁通偏差的新控制方法。实验结果验证了所提控制方法的可行性。

Occurrence and suppression of DC-flux deviations in a doubly-fed flywheel generator system

This paper deals with DC-flux deviations occurring in a doubly-fed flywheel generator with stator-current feedback control. An AC output voltage of the PWM inverter connected to the rotor produces the DC-flux deviations in the stator. It is difficult to detect the DC flux from the stator current and/or voltage, because the DC flux induces no electromotive force on the stator windings. This paper proposes a new control method for suppressing the DC flux deviations based on calculating the magnetizing current from the stator and rotor currents. Experimental results verify the viability of the proposed control method.
