Özet:

In this thesis, a dynamic model for a horizontal axis wind turbine is developed for an upwind configuration using the MATLAB/Simulink environment. Blade Element Momentum Theory is used to model the rotor. It is assumed that the rotor blades are rigid and wind speed is uniform. Aerodynamic and gravitational forces are calculated as distributed loads. Verification of the model is done by using the LMS Samtech, Samcef for Wind Turbines software. Aerodynamic properties of the blades, sectional loads and moments acting on the blades sections and performance outputs are compared for verification. Generator torque controller is designed to maximize power conversion at below rated regime. For above rated regime, a pitch controller is designed to keep generator speed at rated value. .
