摘要
为了避免风电场中尾流效应对风力机之间的相互影响,而找出不同排列方式下风力机之间的最佳距离,文章采用CFD商用软件对两台风力机分别在串列、并列以及三台风力机在错列的排列方式下,采取不同的安装间距进行模拟,根据其功率输出结合尾流理论和实际情况,找到了不同排列方式下风力机之间的最佳距离。通过对单台风力机、两台风力机并列和串列以及3台风力机错列进行了模拟计算,其结果表明:两风力机串列布置时,上游风力机对下游风力机影响甚大;并列布置时,两风力机之间影响甚微;错列布置时,下游风力机处在两个上游风力机的中间,避免了上游风力机尾流直接的影响。
To avoid the aerodynamic interaction among wind turbines by the wake effective in a wind farm, and find the best distance between two wind turbines in different arrangement. Two wind turbines was simulated by using CFD commercial software in both parallel arrangement and tandem arrangement and three wind turbines in staggered arrangement with different distance. The optimal distance was found according to the output power combining the wake theory and the practical situation in different arrangement of wind turbines. The results of simulation for one single wind turbine, two wind turbines in both parallel arrangement and tandem arrangement, and tree wind turbines in staggered arrangement, show that the wind turbine in upstream has a big influence of aerodynamic interaction to the wind turbine in downstream when the tandem arrangement was used, and there is almost no influence between wind turbines in parallel arrangement, and for the staggered arrangement, the downstream wind turbine is in the middle of the wake of two upstream wind turbines, which permits it to avoid the impact from the wake of two upstream wind turbines.
