| 摘 要： | 本文将中尺度气象模式MM5和以流体力学计算为核心的风资源评估软件WindSim相结合,对鄱阳湖地区复杂地形条件下的风能资源状况进行了高分辨率的数值模拟评估,通过模拟结果与同时段铁塔观测数据的对比分析发现:MM5的3km分辨率模拟可以较准确的得到湖区风速的量值,能大致模拟出湖区风速分布趋势以及年主导风向,但是对更精细的局地风况分布的模拟相对过粗,而"中尺度模式+流体力学软件"的方法可以较好的刻画出复杂地形条件下的局地风况,使局地风速的模拟量值与观测结果更为接近,尤其对10m高度的风速模拟结果改善最明显,故认为该方法可作为复杂地形条件下的风电场开发的前期风资源预评估手段之一.

| Abstract: | In order to propose a new method for better assessing wind energy resources under complex terrain conditions,wind energy resources of high resolution over the Poyang Lake areas were simulated with the combination of the mesoscale meteorological model MM5 and wind resource assessment software WindSim,computational fluid dynamical(CFD)software.First,the wind energy resources of high resolution over the study areas were simulated by the MM5 model on a daily basis for a whole year from September 1,2005 to Augus... |
