| 摘 要： | 针对目前双馈感应风力发电机(DFIG)采用背靠背结构通过网侧变流器与电网相连,提出了一种采用直接功率控制方案,直接功率控制(DPC)仅需要测量交流侧的电压与电流,计算出瞬时有功功率,无功功率。与参考的有功功率,无功功率进行比较来控制网侧变流器。该方法能对直流侧电压有良好的控制,同时能保证网侧变流器接近单位功率因数运行。

| Abstract: | Aiming at the present Double-fed Wind Power Generating（DFIG） using back-to-back structure to connect grid through the grid-side converter,a plan adopting direct power control（DPC） is proposed.Direct power control（DPC） only needs to measure the ac voltage and current;calculate the instantaneous active power and reactive power.The active power and reactive power are compared to control net side converter,which can have good control for dc voltage,and can ensure operation of the grid-side converter unit power factor. |
