A virtual reconstruction method of floating wind turbines based on scaling design and integrated simulation
In the integrated design of floating wind turbines,floating platform design companies can only design floating platforms and mooring systems based on tower base load data,due to the incomplete disclosure of wind turbine parameters by wind turbine manufacturers.In response,this paper proposes a virtual reconstruction method for wind turbines based on scaling design and integrated simulation.Through trend fitting of each parameter,this method reconstructs the key parameters of the wind turbine blades and the control system,and it is applied in the"CNOOC Guanlan"7.25 MW floating wind turbine project.The optimal design of the wind turbine control system is carried out to select appropriate parameters for ensuring the smooth operation of the wind turbine.Finally,an integrated coupling analysis is carried out to verify whether the dynamic response of the reconstructed wind turbine meets the accuracy requirements.The results indicate that this proposed method can effectively reconstruct the key parameters of the target wind turbine.The rated power reaches 7.25 MW,and the dynamic aerodynamic performance is stable,with the power curve and the thrust curve being reasonable.The deviation of average crucial tower base loads between the reconstructed wind turbine based on integrated simulation calculation and the target wind turbine is less than 10％,and the tower base loads fit well.This wind turbine reconstruction method has been validated by its application in"CNOOC Guanlan".It can provide essential technical support for the engineering design of floating platforms and mooring systems for floating wind turbines.
