Research on the Repetitive Control Technique in Gird-Side Converter of the Double-Fed Wind Power System

Abstract:

With the unit capacity of the wind turbine is increasing, analyzing, suppressing of gird harmonic and reducing the grid harmonic pollution by the wind turbine have become one of the issues of common concern. For the characteristic of the grid voltage harmonic components which is the interference source with the fixed period, the repetitive control theory was adopted to design the gird-side converter, and the traditional control strategy of the voltage current double closed-loop was compared with the repetitive control. Harmonic suppression characteristics were studied in the paper. Finally, Matlab-Simulink simulation software established a repetitive controller simulation model of the gird-side converter controller, simulation results showed the correctness and feasibility of suppression for the periodic harmonic by the repetitive control strategy.
