Pitch Angle Control for Variable Speed Wind Turbine using PI Controller

Abstract

The renewable energy sources such as wind and solar energy have taken their place in exchange for the conventional sources, which have greater impact on the environment. This thesis presents the design and analysis of Wind Turbine Control System (WTCS). It gives mathematical models for its various components, such as wind turbine, drive train, generator shaft, and the controller system. This simulations based on the system model has been implemented using MATLAB version R2014a. For the improvement of the system stability a Proportional Integrity (PI) controller has been designed and implemented with the model. The results show enhanced output power and better overall performance in a wide range of wind speeds.
