摘要
针对掌握复杂地形区域内的风能分布对风电场微观选址有重要作用的问题,采用计算流体力学(CFD)技术,基于商用软件FLUENT平台,数值模拟了峡谷地形中风流流动规律,对比分析了主导风向、地形坡度及地面粗糙度三种主要影响因素变化时风场风速的分布情形,可为此类地形风电场的风机机位布置和塔架安装高度提供参考。
For micrositing a wind farm, it is significant to be informed with the distribution of wind energy across complex terrain. The commercial software FLUENT is used to simulate wind flow in valley terrain by using computation- al fluid dynamics （CFD） technology. Three major factors, the terrain slope, the surface roughness and the dominant wind direction, are simulated to analyze their influences on the distribution of wind velocity, which can provide basis for plan- ning the layout of wind farm and determining the installation height of the wind turbine tower.
