Behaviour of wind turbine under different operating modes

In wind energy conversion system the wind turbine captures the kinetic energy associate with the wind for the production of electricity with the help of generator. Performance of a wind turbine is dependent upon its operating conditions such as wind speed as well as its design parameters such as blade radius, blade pitch angle, weight etc. In the present paper, authors have made an attempt to develop a MATLAB/SIMULINK model of wind turbine. Model as developed is suitable to investigate its performance under constant as well as variable speed mode. Simulated results as obtained are found to be useful to predict the effect of wind speed and blade pitch on the performance of wind turbine under two operating modes.
