摘要
利用Agel-TDM风力机动力模型,模拟分析不同湍流状态下单台风力机尾流的空间特征。研究结果表明:随着大气湍流稳定性增强,在水平方向上风力机尾流效应减弱,即风力机尾流距离减小;在铅垂方向,动量垂直输送加快,增强了风力机下游风速的恢复速率,风电场的实际出力能力提高。
In this paper,the spatial characteristics of a single turbine in different turbulence states are numerically simulated by using the Agel-TDM wind power model.The results show that,with the increase of atmospheric stability,the wind turbine wake weakens in the horizontal direction with the increas of atmospheric stability,but in the vertical direction,vertical momentum exchange is accelerated so that the recovery rate of the wind speed at the downstream of the turbine is enhanced and the actual output capacity of wind turbine is improved.
