摘　　要：风电场测风塔测风数据的质量直接影响风能资源评估的结果,进而影响整个风电场投产运行后的经济效益。平均风向在测风塔缺测数据的插补、延长以及代表年订正过程中具有重要的作用。文章主要提出了一种基于概率统计的平均风向计算方法,并讨论分析了其在实际风电场工程应用中的准确性和实用性,为设计工作提供更多解决问题的方法。The quality of wind data from met mast has a directly influence on the results of wind resource assessment,so as the financial benefit of the operation wind farm. Average wind direction is playing a curial role in the design process of interpolation and prolonging of missing wind data,so as to the typical correction of measuring data. This paper put forward a calculation method of average wind direction based on probability statistics, and accuracy and practicability of this method in practical wind farm engineering are analyzed and studied,which provides more efficient solutions for the wind farm engineer.
