摘　　要：代表年法是风能资源计算中的重要方法,而对区域风能资源代表年的选取方法不一。以江苏省为例,对区域多站点的风能资源代表年选取的两种方法——"站点最大频数法"和"区域平均法"的比较分析表明,两种方法选取的江苏省风能代表年是一致的。本文的结果可以推广到其它多站点区域的风能资源代表年的选取上,其中站点最大频数法简便易操作,适用于较少站点数条件下的代表年选取和业务性运用;区域平均法适用于稠密站点条件下的代表年选取;在样本足够大条件下,上述两种方法的计算精度能够满足风能利用的业务和研究需要,并具有足够的区域一致性和代表性。Selections of representative years are very important in long-term wind energy potential calculations, but the methods are varied one another in calculating regional values. Based on the surface observed wind data from 1971 to 2000 in Jiangsu, two different methods, i.e. the station maximal frequency method and the regional average method, are presented and compared in this paper. The results show that the two different methods select the same representative years. The methods can be applied in other regions which contained multiple stations. The station maximal frequency method is simpler for operational application and for dealing with less stations, whereas the regional average method is better for dealing with more stations. Under the condition of enough sample numbers, the accuracy of both methods are good enough for operational and study needs.
