针对大型风电场尾流评估问题,考虑大气边界层垂向动量输运和风电场内流动不均匀性,提出一种基于传统尾流模型和风电场边界层模型的耦合求解方法。采用Horns Rev风电场和青海锡铁山矿区风电场群实测数据对所提出的耦合方法进行验证,结果显示该方法可较为准确的评估大型风电场的场内、场间尾流效应,对大型风电场和集群化风电场开发具有重要理论和工程应用价值。
Abstract
The development of large-scale and clustered wind farms has brought new challenges to the evaluation of the wake effects. To address this issue, a coupled method based on the traditional wake model and the wind farm boundary layer model is proposed considering the vertical momentum transport in the atmospheric boundary layer and the flow inhomogeneity in the wind farm. The proposed coupled method is verified by the measured data of the Horns Rev wind farm and the Xitieshan wind farm cluster. The results show that the coupled method can accurately calculate the wake effects inside and between large wind farms, and may have important theoretical and engineering significance to the future development of large-scale and clustered wind farms.
