As the energy demand and greenhouse gases emission is increasing day by day the popularity of renewable energy systems is also being raised. One of the most popular renewable energy systems over the past decade has been the wind energy or wind turbines. Wind turbine extracts kinetic energy from the wind. Currently much research has concentrated on improving the aerodynamic performance of wind turbine. Variable speed horizontal axis wind turbines use blade pitch control to meet specified objectives for three regions of operation named low wind, medium wind and high wind conditions. In this paper a control strategy is being developed for variable speed horizontal axis wind turbine which will allow the turbine to run at its maximum efficiency. For this purpose the PID controller based pitch actuator system is used to control the aerodynamic power of wind turbine. MATLAB Simulink power system tool is used to develop the model of PID controller. In this paper a model for the simulation of the PID controller based pitch actuator system is constructed using properly selected sub blocks. Step response of this PID controller based pitch actuator system will be analyzed. The above presented model can be a useful tool for wind power industry to study the behavior of wind turbines.
