海北州风能资源的初步探析

Primary Approach on Wind Energy Resources in Haibei Station

取1976—2005年海北州海晏、刚察、祁连、门源四县的资料分析了风速、风向的日、年、年际变化、大风日数。分析表明:海北州风速一日之中6—7时最小,下午16—17时最大;一年之中风速春季最大,夏季最小;全年最多风向频率为东南、西北;大风日数春季最多、秋季最少,且自1976年以来呈逐年减少趋势;计算全州各县风能资源的储藏量发现,风能资源以刚察为中心,门源最小。

The wind speed,the wind direction change in day, year, interannual and days of gale were analysed from 1976-2005 in Haiyan,Gangcha,Qilian and Menyuan of Haibei wind material,the results showed the Hai bei station wind speed 6-7 o＇clock werethe smallest in a day and 16-17 o＇clock were biggest; in a year the spring＇s wind speed were biggest and the summer were smallest, the frequency of wind direction in a year were SE and NW, the days gale in spring were most and antumm were fewest,the trends presented decrease year by year since 1976, the resources of wind energy all station showed the Gangcha was centre and Menyuan was fewest.
