Modeling and simulation of pitch controlled FRP material based horizontal axis wind turbine system to extract maximum power

Abstract

Wind energy is clean form of energy which is abundantly available. A great deal of study has been carried out lately in order to utilize the wind energy available on a large scale as it does not affect the environment and it is a sustainable source of energy. The modelling and simulation of wind turbine system supports mainly in improving the design and performance of the wind turbine. In the past few years, MATLAB©-Simulink© became one of the most common software, which is important for modelling, and simulation of dynamic systems. The use of MATLAB© in modelling and simulation of dynamic real-world systems is unprecedented. As the MATLAB© provides graphical interface, it gives clear picture about the performance of wind turbine in a real-world scenario and model accordingly. In this study, a horizontal axis wind turbine with variable pitch mechanism is considered and simulated it in MATLAB©-Simulink© by varying the wind speed and pitch angle. The active power output of the turbine varies with the wind speed and the angle of attack (β). Based on the results, it is found out, the optimum characteristics of wind turbine like pitch angle and turbine speed is obtained at various wind speed. Therefore, by simulating and analysing the results, it is found out that the maximum active power output of the turbine is achieved at the optimum pitch angle.
