چکیده
In this paper we present the modeling and control designs for a variable-speed constant-frequency wind energy conversion system using double fed induction generator (DFIG). The aim of this paper is to design and compare two distinct control strategies to control the rotor side converter and two control strategies to control the grid side converter. For the rotor side converter (RSC), a backstepping control strategy is firstly developed. Secondly, a sliding mode control strategy is presented. The same strategies to control the grid side converter (GSC). Simulation results using Matlab/Simulink have shown good performances of the wind energy converter system operate under typical wind variations and every propose control strategies.
