| 摘 要： | 随着新能源行业的深入发展,风电行业发展更为迅速,对于一个风电项目而言,研究其风资源分布特性尤为重要。中国内陆地形较为复杂,大部分为山地丘陵。受地形的影响,风资源分布特性较为复杂,评估较为困难。先建立余弦型的丘陵地形物理模型,分别采用CFD数值模拟、风洞实验2种方法对丘陵地形周围流场进行模拟仿真与实验测试,通过对丘陵迎风坡、背风坡特定参考点水平风速、垂直风速变化特征的分析,归纳总结了丘陵地形周围风资源分布特征,为丘陵地形下风能开发利用提供一定的参考。

| Abstract: | With the in-depth development of the new energy industry,the rapid development of the wind power industry,it is par-ticularly important to study the wind resources distribution characteristics for a wind power project.The land shape in China is relatively complex,most of which are mountainous and hilly terrain.Due to the influence of topography,the distribution of wind resources is relatively complicated and it is difficult to evaluate.This paper first established a cosine-type hilly terrain physical model,and used CFD numerical simulation and wind tunnel experiment to simulate and test the flow field around the hilly terrain.Through analyzing the change characteristics of the horizontal wind speed and vertical wind speed of the hilly windward slope and the leeward slope at specific reference points,it summarized and summarized the distribution characteristics of wind resources around hilly terrain,to provide certain reference for the development and utilization of wind energy in hilly terrain. |
