摘　　要：以内蒙古地区某风电场风资源分析为例,探讨采用常规的16风向扇区风速相关方法和简化后的8风向扇区和4风向扇区方法对代表年风速的订正所产生的误差情况,结果表明:4风向扇区风速相关性优于8风向扇区风速相关性,两者又都优于16风向扇区风速的相关性;采用4风向扇区和8风向扇区风速相关性进行修正得到的代表年月平均风速的结果与16风向扇区风速的相关性进行修正得到的代表年月平均风速的结果一致。Based on the assessment of the wind resources in a certain wind farm in Inner Mongolia,this paper presents an error analysis on revising the representative wind speed by the conventional 16-sector wind direction relation method and by the simplified 8-sector and 4-sector wind direction relation method,respectively.It is found that the wind speed relation of 4 wind direction sectors is superior to that of 8 wind direction sectors,while both are superior to that of 16 wind direction sectors.The revisited result of the representative monthly average wind speed obtained by the 4-sector and 8-sector wind direction relation methods is consistent with the revised data obtained by the 16 wind direction sectors relation.
