A new control strategy of the grid-connected converter in the system of the doubly-fed wind turbine was presented. Operation process of this grid-connected control strategy was detailed,the mathematical model of the grid-side converter and timely control loop entry were employed to complete the new control strategy. While PSIM was employed to simulate the proposal,through experiment,to verify the correctness of the control strategy. The experimental results show the control strategy has a good transition process and the dynamic performance.
