Abstract
This study presents the dynamic performance of stand-alone self-excited induction generator driven by a variable speed wind turbine using direct torque control strategy. The system consists of wind turbine, self-excited induction generator, voltage source converter and battery with capacitor. The input to the induction generator is wind whose velocity is not constant. The magnitude and frequency of the generator terminal voltage varies with wind velocity. To maintain the voltage and frequency of the induction generator terminal constant; the direct torque control strategy is used. This study investigates the dynamic and steady state performance of self-excited induction generator for varying load and wind speed conditions and short circuit at stator terminals. The proposed system is designed and simulated in MATLAB/SIMULINK environment. The simulation results show the effectiveness of the proposed system.
