As for dual PWM inverters in direct-drive permanent-magnet wind power system under the normal control, when the wind speed changes, the DC bus voltage fluctuates greatly and the control system responds slowly, which is unfavourable to system safe and stable operation. Therefore, according to the instantaneous active power balance relationship, this paper puts forward the control strategy of coordination power feed forward compensation. It makes the generator side of instantaneous active power be a feed forward in the grid side converter of double loop instantaneous active power ring given, avoids the voltage control loop indirect regulation of power, accelerates the respond speed of control system. Moreover, it achieves the coordination of the DC bus side instantaneous active power timely balance, effectively restrains the DC bus voltage fluctuation. In order to strengthen the feed forward control to offset the disturbance, it is necessary to join the compensation in the feed forward control channel, to further improve the feed forward control effect. The comparison of simulation verifies the correctness and effectiveness of the control strategy.
