Simulation de la commande vectorielle par régulateurs à mode glissant d’une chaine éolienne à base d’une machine asynchrone à double alimentation

Abstract

This work present a technique of sliding mode control applied to the system of wind energy conversion equipped with a doubly-fed induction generator. This technique finds its strongest justification for model uncertainty problems by using a nonlinear control law. The goal is to apply this command to control the exchange of active and reactive power generated by the doubly-fed induction generator with the network acting on the rotor signals via a bidirectional converter. The numerical simulation results obtained show the growing interest of such a control in electrical systems. Keywords: doubly-fed induction generator, sliding mode, oriented flux control, power control.
