Abstract: The aerodynamic characteristic of wind turbine was calculated by using Pitt-Peter theory and was programmed in Matlab/Simulink. The drive chain was calculated by applying state space method and also programmed in Matlab/Simulink. The model of the wind turbine was built with Adams. The simulation of vibration characteristic was carried out so that the aerodynamic loads and the torque were applied to the structure of the rotor. Simultaneously the deformation of the structure also affected the loads. The results show that the method has excellent capacity in simulating the vibration characteristic.
