Analysis of Pitch Angle Variation in Asynchronous Generator Wind Turbine

This paper presents the analysis of pitch angle variation in Asynchronous generator wind turbine. The asynchronous generator wind turbine model consists of wind turbine profiles which attribute to the mechanical power and torque characteristics of wind turbine. The simulation model for Asynchronous generator wind turbine has been developed using a MATLAB/SIMULIK. The Asynchronous generator wind turbine model can work as induction generator. The wind turbine simulation model can display generated power and their values changes according to the wind velocity. The torque from the wind turbine simulator can be used to drive the asynchronous generator to generate the power fed into the load. The asynchronous generator wind turbine was tested upon step changes in the wind velocity as well as the blade pitch angle requirement of for power control. Simulation results obtained are encouraging.
