摘　　要：在对风电场进行风资源评估时,常采用气象站与测风塔的相关关系,将现场测风数据订正为一套反映风电场长期平均水平的代表性数据进行风资源分析,而对代表年风速订正是否合理是影响风资源评估误差的重要因素。文章以内蒙古地区某风电场风资源分析为例,探讨采用常规方法和改进方法对代表年风速的订正所产生的误差情况,结果表明,通过改进方法进行修正得到的代表年平均风速的变化规律与气象站多年的变化规律一致,此方法弥补了常规方法中的一些不确定因素对代表年修正结果的影响,减小了误差范围。When carrying out the wind resource assessment,a set of revised representative wind data, which is based on the relationship between the local wind mast and nearby weather station, is always used to carry out the analysis on the wind source, and the determination of the representative wind speed is the key faetor which influenees the error of the assessment. In this paper, an error analysis has been taken between the conventional method and the improved method through assessing the wind resource of a wind farm in Inner Mongolia. It is found that the revised wind resouree in the representative year is consistent with that of the nearby weather station. Moreover, the imnrowd method has the advantage of less uncertainty and less error.
