Abstract
The influence of aerodynamic loading, hydrodynamic loading on the floating wind turbine and its control system was systematically considered. The fully coupled aero-hydro-servo-elastic dynamic models of three typical floating wind turbines were established, respectively. Based on NREL 5-MW wind turbine, the comprehensive dynamic responses of three floating wind turbines under different load cases were obtained by using FAST code with AeroDyn and HydroDyn subroutines, and compared with the onshore wind turbine with the same baseline in the corresponding working condition. The results showed that the influence of coupled aero-hydro dynamic loading on the dynamic response of wind turbine is obvious, and the responses of different floating wind turbines have obvious differences. The maximum load acting on the floating wind turbine is increased relative to the onshore wind turbine. Especially, the maximum tower-base bending moments of the Barge and the Spar-Buoy floating wind turbines increase 1.4 times more with respect to onshore wind turbine. Barge platform and TLP platform have better stability as offshore wind turbines platforms.
