【摘要】：利用分布在湖北省丘陵山区的12个70m(80m)高测风塔一整年的资料,对我省丘陵山区风能资源的若干特征进行了较为详尽的对比分析,找出其中普遍的规律。结果表明:(1)我省山区风速季节变化为春季大,夏季和秋季较小;风速日变化为夜间大白天小,且变化幅度相对较大的测风塔主要分布在低山和中山区域;(2)有效风速频率在79%~92%,破坏性风速出现少;(3)风向频率较为集中,主要分布在偏南和偏北两个相反的方位;(4)风速随高度变化较复杂,10~30m高度风速增加幅度较大,部分地区30~80m高度存在等风层或风速随高度减小的情况;(5)有效风速段、大风及主导风向下的湍流强度均为中等。研究成果对湖北省,甚至是南方山区风能资源的合理开发利用将有所裨益。
[Abstract]:The distribution in the 12 70m of Hubei Province in mountainous and hilly areas (80m) high tower a year of data, some characteristics of wind energy resources in our province in Hilly and mountainous areas are analyzed in detail and find out the general rule. The results showed that: (1) the seasonal wind speed change in the mountainous region in spring and summer and smaller in autumn; the diurnal variation of wind speed at night during the day, and the change was relatively large wind towers are mainly distributed in the low mountain and Zhongshan region; (2) the effective wind speed frequency in 79%~92%, damaging winds appear less; (3) the wind frequency is relatively concentrated, mainly distributed in the South and north two opposite orientation; (4) the change of wind speed with height is relatively complex, 10~30m high wind speed increases greatly, the presence of parts of 30~80m height decreases with height of wind or wind speed; (5) the effective wind speed, turbulence intensity and wind down wind leading were medium. Research The results will be beneficial to the rational exploitation and utilization of wind energy resources in Hubei province and even in the southern mountainous area.
