摘要
复杂地形的风能资源评估研究对于风电事业的发展具有极为重要的意义。作者利用基于计算流体力学(CFD)方法的风能资源评估系统软件WindSim对我国复杂地形新疆托克逊县境内某风电场2007年的风资源情况进行了模拟,并将模拟结果与测风塔观测结果进行对比分析。模拟结果表明,WindSim软件对我国复杂地形地区平均风速的模拟能力比较好,10m、40 m、50 m、70 m高度的月平均风速的平均相对误差分别是12.91%、10.21%、9.68%、12.91%。同时,WindSim软件不仅可以较为准确地模拟出该区域2007年的主导风向,而且对该年的有效风速频率的模拟效果也很好。此风电场风能资源模拟试验说明,该地区具有十分丰富的可供开发利用的风能资源,进一步说明WindSim软件对我国复杂地形地区的风能资源评估工作具有很好的参考和应用价值。
The wind energy resource assessment in a complex terrain is very important for the development of wind power generation field.Wind energy resource assessment software WindSim based on the Computational Fluid Dynamics（CFD） method is applied to simulate the wind energy resources of wind farm area in Toksun,Xinjiang in 2007.By comparing simulation results and observation data measured by anemometer towers,it is shown that the software WindSim provides good simulation results of mean wind speed in a complex terrain area,and the mean relative errors of monthly mean wind speed at 10 m,40 m,50 m and 70 m are 12.91%,10.21%,9.68%and 12.91%respectively.Moreover,the WindSim is able to accurately simulate the predominant wind direction at 40 m and 70 m height.At the same time,the WindSim can also obtain good results of effective wind speed frequency in a complex terrain area.The simulation results of wind energy resources in wind farm show that the area has rich wind energy resources which can be used by wind power generation.It is further indicated that WindSim software can be utilized in the assessment of wind energy resources of complex terrain and has further research value in the future.
