The Design of Direct-Drive Wind Generation Grid Side PWM Converter Based on LCL Filter

Article Preview

Abstract:

This paper gives systematically study on grid-side converter with LCL filter for doubly-fed induction generator in wind power. This paper adopts the parameters of the PI-based controller that is already used for the L-filter-based active rectifier. On the basis of model in the dq coordinate system, the paper proposes a double-closed-loop control strategy. Then the simulation model of PWM rectifier is established in the MATLAB/SIMULINK environment. According to the articles theory imitation of the real system design with good dynamic and static performance.
