Evaluation of the behavior of a horizontal axis wind turbine subjected to wind loading

Resumo

Due to the advances in wind energy, it became necessary to better understand the structural and
mechanical behavior of wind turbines. This work presents the modeling of the 5 MW baseline wind turbine,
developed by the National Renewable Energy Laboratory (NREL) in the USA, considering an onshore structure
with 3 blades. Through the SAP2000 structural model, it was obtained the natural frequencies and modes of
vibration, while the dynamic response of the structure, when submitted to wind cases asIEC 61400-1, was obtained
through the software FAST.
