| Abstract: |
| Floating offshore wind turbines are capable of exploiting the abundant deepwater wind resource.Because of the existing large motion of the floating platform,such as the yaw,the pitch and the surge motion,the interaction between the wind flow and the wind turbine blade will be changed,which will effect its aerodynamic characteristics.Considering the changed wind inflow velocity at different radial position along the span direction of the blade induced by the floating foundation motion,the aerodynamic load is calculated based on the blade-momentum theory and its various modified formulas.Taking the NREL 5MW sample offshore floating wind turbine as an example,the torque and power results are compared under different floating foundation motions.The analysis results show that the pitch motion has the most great effect on the power fluctuation,and are helpful to optimize floating offshore wind turbine design. |
