Constant Torque Control Schemes for PMSG Based Wind Energy Conversion System

In this paper, the operation of wind energy conversion system is introduced by modeling of constant torque control schemes. Proportional-Integral, Fuzzy logic and Artificial neural network based schemes are proposed to control the blade pitch angle and tip speed ratio. A MATLAB/Simulink model is developed for the wind turbine based power generation system by combining the designed controllers. The system performance is tested under different operating condition for each controller assisted wind energy conversion system and found satisfactory. Furthermore, a comparative study is made in terms of controller response and control parameters.
