Abstract

In this paper we present the control system of a wind turbine based doubly fed induction generator (DFIG) by direct torque control (DTC). The wind energy conversion system (WECS) equipped with wind turbine, DFIG, DC bus and the power convector. The converter is controlled to generate the maximum power from wind turbine generator (WTG) by using maximum power point tracking (MPPT) strategy. The pitch control is also proposed to limit the generator power at its rated value. The DTC is developed to regulate the flux and torque. The simulation results of a 1.5MW doubly fed induction generator show the performances of the control strategy proposed. These results are validated by using the MATLAB/Simulink environment.
