Response characteristics analysis of 10 MW TLP wind turbines under extreme conditions

FAST is used to construct a fully coupled nonlinear model for the simulation of 10 MW floating wind turbines. For the extreme case, the key components of TLP wind turbines, such as blade, tower and platform, were studied by coupled solver FAST. The results show that under the maximum operating condition, TLP wind turbine's blade are subjected to greater loads, but under the extreme shutdown condition, the tower bear greater bending moment and shearing force. The response of TLP are more severe under extreme shutdown condition. The structural check of the wind turbine's blade should be based on operating condition, while the structural checks of other components should consider extreme shutdown conditions. © 2019, Editorial Board of Acta Energiae Solaris Sinica.
