For the grid-connected system of the direct-drive wind power generation, the mathematical model of inverter was deduced through analyzing the working principle of the grid-connected inverter. Simultaneously, the control strategy of the outer voltage loop and the inner current loop were Put forward. Simulation results showed that control system with the above control strategies had better advantages such as rapid current-tracking performance, quick response ability and small amount of harmonic component.
