摘要
根据空气动力学原理推导单台风电机组尾流模型,建立多台风电机组的尾流叠加模型。在此基础上,提出一种全场尾流快速计算方法,该方法用经过坐标原点的直线来表示不同的来流风向,计算各风电机组沿此直线方向到坐标原点的距离,以此距离确定风电机组的迎风顺序,根据风电机组单台尾流模型、尾流叠加模型及风电机组的迎风顺序,计算整个风电场的尾流分布。以丹麦Horns Rev风电场为算例进行计算分析,结果表明,该文所述的尾流快速计算方法能准确、快速计算风电场尾流分布。
The single wind turbine wake model was derived according to the principle of aerodynamics, and the superposition model of multiple wind turbines was established; on this basis, a fast calculation algorithm of wake was proposed, in this algorithm, a straight line through the origin of coordinates was used to represent the different wind direction, the distance of each wind turbine to the origin of coordinates along the straight line direction was calculated, the order that wind turbines meet wind was determined according to the distance, the whole wind farm wake distribution could be calculated according to single wind turbine wake model, wake superposition model and the order that wind turbines meet wind. The Horns Rev wind farm in Denmark as an example to be calculated and analyzed, the results showed that the wake fast calculation algorithm described in this paper can accurately and quickly calculate the distribution of the wind farm wake.
