三种典型海上浮动式风力机动力学特性比较分析

his study systematically consider the influence of aerodynamic loading, hydrodynamic loading on the floating wind turbine and its control system. Establish fully coupled aero-hydro-servo-elastic dynamic models of three typical floating wind turbines respectively. Based on NREL 5-MW, comprehensive dynamic-response of three floating wind turbines under different load cases was obtained by using FAST code with AeroDyn and HydroDyn subroutines and was compared with the onshore wind turbine which has the same baseline under the corresponding working condition. Results show that the coupled aero-hydro dynamic loading has a great influence on the dynamic response of wind turbine, and the responses of different floating wind turbines have obvious differences. The maximum loads acting on the floating wind turbines were increased relative to the onshore wind turbine. Especially, the maximum tower-base bending moments of the Barge and the Spar-Buoy floating wind turbine are increased 1.75 times more with respect to onshore wind turbine. Barge platform and TLP platform have better stability as offshore wind turbines platforms.
