| Abstract |
We present in this paper a control of an induction generator wind turbine connected to the grid. We applied a modulated hysteresis direct torque control (MHDTC) to the induction generator (IG). This control strategy consists in superposing to the torque reference a triangular signal, as in the PWM strategy, with the desired switching frequency. We obtain a new modulated reference which is compared to the estimated torque by using a hysteresis controller as in the classical direct torque control (DTC). The aim of this method is to obtain constant frequency and low THD in grid current with a unit power factor. A comparison is made with classical direct torque control and field oriented control method (FOC). The obtained simulation results, using Matlab/Simulink, show an adequate dynamic of the studied system under the proposed method. |
