This paper studies the interaction between the wind load and the motion of the floating foundation of the floating offshore wind turbine system quantitatively.The integrated coupling dynamics model of the floating wind turbine system was established,and the influence of wind load on mooring force,floating foundation motion,nacelle acceleration and floating foundation motion on the relative velocity of blades,blade thrust and power generation were compared and ana-lyzed.The results show that wind load significantly affects the mean value of sway/pitch of the floating foundation,and has little effect on its standard deviation.Wind load has a certain effect on the mean value and standard deviation of mooring force,while the acceleration of the nacelle is not greatly affected by the wind load.The motion of the floating foundation has a significant influence on the standard deviation of the relative wind speed of the blades.The farther the position from the hub is,the greater the relative wind speed is affected by the foundation motion,which leads to great fluctuations in the thrust and power generation of the floating wind turbine blades.In order to ensure stable power generation,the influence of the floating foundation motion should be considered when designing the control system of the floating wind turbine.
