基于CFD的复杂地形风能分布研究

摘要

Numerical simulations were carried out by using the Fluent software with a mesh generated by using the Argis software to predict the wind speed distribution in complex terrain.The post-processing by Tecplot was used to get the wind speed distribution characteristics and the wind energy distribution in the whole wind field.The obtained results were compared to the calculated results with WAsP software.%提出一种通过计算流体力学(CFD)计算风电场风速和风能分布的方法,该方法通过Argis软件对风电场CAD等高线图进行离散处理,按照风速玫瑰图分布,利用Fluent软件对复杂地形条件下风场按照12分度进行数值计算,并按照风速风向分布概率由Tecplot软件进行后处理,得到整个风场的风速分布特点和风能分布.将计算结果与WAsP软件作比较,结合地形特点进行分析,认为本文计算方法得到的结论较为可靠.
