Abstract
With the development of wind energy industry, the application of floating wind turbine has been largely solved at the technical level. Since the floating wind turbine has six additional degrees of freedom, the dynamic response of its rotor and the wake characteristics also change accordingly. Compared with offshore bottom-fixed wind turbines, the wake of floating wind turbines has a different impact on the power output of downstream units. A Spar-type floating wind farm model is established, and simulation calculations are carried out under medium and low ambient wind speeds. By using scatter plots, box plots, etc., the time series data of the displacement of the rotor and the position of the center of the wake are compared and studied. The conclusions are as follows: Spar-type wind turbine has a wider range of motion of the rotor, and the wake is more dispersed. Meanwhile, the wake effect of Spar-type wind turbine has a wider range but a weaker degree of influence to the downstream units. Floating wind farms composed of Spar-type wind turbines have higher power output under the same external environment.
