Short summary
This paper studies the effect of the tower dynamics upon the wind turbine model by using mixed sets of coordinates within multibody system approach. The dynamics of wind turbine model is presented based on the floating frame of reference formulation. The mixed coordinates consists of three sets: Cartesian, elastic, and reduced-order modal coordinates for low speed components. Experimental validation has been carried out successfully, and the model can be utilized for design process.
