摘　　要：利用内蒙古地区2个风电场内6个测风塔18个测风高度完整一年的测风数据及该地区高分辨率的数字地形资料,采用风电场内一个参考塔的测量结果,通过WT推导风电场内目标塔的结果,比较推算结果和实际测量结果。结果表明:WT在该文2个风电场的推算结果基本能够反映该风场风能资源的变化情况,在A#风电场各测风高度推算值的月平均风速与实测值的月平均风速相对误差较小,在B#风电场中相对误差较大;从线性关系分析,无论是风速还是风功率密度,A#风电场的推算值与实测值的相关性优于B#风电场;WT对风电场无测风点风速的推算结果可作为无测风记录区风能资源初步评估的辅助资料,但仅以此推算结果作为风电场风能资源评估的依据还存在欠缺。Wind resource calculation was taken for two wind farms with different complex terrains, Wind data connected at the eighteen measurement heights of six monitoring masts in. the two farms in one complete year were used for the calculation. The general wind resource assess- ment software WT. Wind measurements at one reference point of the site, was taken as input to transfer wind conditions for other target points for which wind measurements were available. Through comparing the calculation results with the measurements at the target points, the calculation results from WT indicated ： the calculation result by WT could basicly reflect the change of wind resource, but A# wind farm generally performed better than B# for the calculation of monthly average wind speeds ; through analysis of linear relation, no matter it was wind speeds or wind power densities, A# wind farm was better than B# for the linear relation of the calculation result and the measurements ; It was advisable to use the calculation results from WT as the supplementary material of wind resource assessment at having no wind data, but only using it as the basis of wind resource assessment is deficient.
