Wind Turbine with Induction Generator Controlled to Extract the Maximum Power

This paper proposes a novel control system for fixed pitch wind turbine using an induction machine. It can obtain the maximum wind power for each wind speed without a wind speed sensor. The system measures the power generated by the turbine and changes the generator speed to increase the generated power. The induction generator is voltage source controlled. The good system performance is tested using simulation models and variable speed wind profiles.
