Resumo

Currently, the design and development of MWs wind turbines are based mainly on results from computational simulations using aeroelastic code. The wind turbine dynamics can be analyzed through experimental measurements or simulations using numerical computational codes. The aim of this work is to perform a preliminary turbine analysis and dynamic simulations through steady calculations which allow the user to analyze the performance of the turbine as a function of wind speed. To perform these simulations, a numerical model of a wind turbine present in the aeroelastic code was used and 21 degrees of freedom were analyzed for estimating the performance, the structural loads and the dynamic responses (8 degrees of freedom for the blades, 2 for the drive train, 3 for the nacele and 8 for the tower).
