Using double closed- loop vector control strategy of the voltage and current based on beamed grid voltage, the grid inverter control is carried out. The simulation experiment shows that the output active power and reactive power can be independently regulated, the feed- in grid current has the less rate of aberration of humorous, and the current of AC side is sine wave. The wind generator system has excellent dynamic and static performance. Key words: direct- drive wind power system, permanent magnetic synchro
