This paper focuses on the grid side converter which is used for the double-fed induction wind power generation system.On the basis of the analysis of the mathematical model,using the Direct Power Control active disturbance rejection controller(ADRC)control the grid side converter.And using MATLAB/Simulink simulation software to make simulation experiments for the design of the controller,simulation results show that the control strategy can ensure the DC bus voltage stability, grid-side power factor is 1, and when a disturbance or perturbation occurs,theADRC control strategy has stronger robustness than the traditional PI control strategy,and the control results are satisfactory.
