摘　　要：【目的】导流板可以改变风电场流量分配,在现有风电场中,增设导流板是提高风力机捕获风能的有效方法之一。为量化导流板影响,通过设置导流板工况,得到不同工况下风场速度分布以及风力机输出功率。【方法】将导流板倾角、长度、导流板与风力机间距3个因素进行3水平正交组合,基于雷诺时均Navier-Stokes (Reynolds averaged Navier-Stokes,RANS)方法进行数值模拟,最大限度地提高风力机功率。【结果】不同的导流板倾角、长度、导流板与风力机间距,对风力机入流风速和输出功率产生了不同程度的影响。在这3种影响因素中,导流板倾角对风力机入流风速和输出功率的影响最为显著,其次是导流板长度,最后是导流板与风力机间距。【结论】研究结果为提高风力机输出功率提供了参考依据,有助于优化风能利用中导流板的设计与应用。[Objectives]Deflectors can modify flow distribution within wind farms,and their integration into existing wind farms is an effective method for improving wind energy capture by wind turbines.To quantify the effect of deflectors,various operating conditions of deflectors are established to obtain the velocity distribution within the wind field and the wind turbine output power under different conditions.[Methods]A three-level orthogonal combination of three factors of deflector inclination angle,length,and distance between the deflector and the wind turbine is conducted.Numerical simulations based on the Reynolds averaged Navier-Stokes(RANS)method are performed to maximize the power output of the wind turbine.[Results]Different deflector inclination angles,lengths,and distances between the deflector and the wind turbine have varying degrees of effect on inflow wind velocity and wind turbine output power.Among these influencing factors,the inclination angle has the most significant effect on the inflow wind velocity and output power of the wind turbine,followed by the deflector length,and finally the distance between the deflector and the wind turbine.[Conclusions]The findings provide valuable guidance for improving wind turbine power output and optimizing the design and application of deflectors in wind energy utilization.
