海上漂浮式与固定式风机串列排布尾流特性及风电场功率对比OA

This paper employs a coupled aero-hydro-servo-elastic approach combined with a dynamic wake meandering model to numerically analyze the tandem arrangement of 5 MW semi-submersible floating wind turbines and 5 MW bottom-fixed wind turbines.Initially,an integrated numerical model of the tandem arranged turbines is constructed using FAST.Farm software,and the numerical results are compared and validated with the large-eddy simulation results from the reference.Subsequently,this paper numerically researches the wake characteristics of the two turbines under turbulent conditions,and compares the wake velocity decay and turbine power characteristics under different tandem arrangements of bottom-fixed and floating wind turbines.The results indicate that under the same spacing arrangement,the floating wind turbines exhibit a faster wake recovery than bottom-fixed turbines,thereby reducing the impact on downstream turbines and increasing the power output.Additionally,in a tandem mixed arrangement of bottom-fixed and floating wind turbines,it is recommended to place floating wind turbine upstream and bottom-fixed turbines downstream to maximize the total power output of the wind farm.
