A control system for direct drive wind generation system with the dual pulse-width modulation( PWM) converter was established. In this control scheme, the generator-side converter was used to maintain a stable DC-link voltage, while the grid-side converter realized the maximum power point tracking(MPPT). In this system, a unity power factor control strategy was described. The operation capacity of this system could be reduced. Simulation results showed that the control strategy can achieve unity power factor and maximum power point tracking.
