Aplicação de controle de potências para a geração eólica e filtragem de corrente harmônica com gerador de indução duplamente alimentado.

Abstract

This paper describes a new proposed wind power system which controls the active and reactive generated power as well as performs filtering of the grid currents harmonic components. The harmonic compensation is achieved by an algorithm applied for grid side converter in the presence of a non-linear three-phase load in the point of common coupling. This technique when correctly used improves the power quality. The machine side converter controls the active and reactive power that is delivered to the grid by vector control with the stator ield orientation. A design methodology of the controllers used in these techniques is presented. Simulation and experimental results confirmed the effectiveness of the proposed system.
