安庆沿江河谷地区风能资源分析

Analysis of Wind Energy in Anqing Valley along River

利用安庆地区1971-2003年9个站点风速气候资料和2005年8月至2006年7月沿江河谷地区陈岭、白岭洲风塔精细资料，研究了安庆沿江地区风能资源特征。结果表明：风能分布存在区域差别，安庆沿江河谷地区（尤其是望江、宿松）环境风速比较稳定，西北部大别山区风速下降明显。全区风能普遍较高，受地形和气候共同影响，安庆市风能资源主要分布在沿江河谷西部，望江、宿松年平均风功率密度为80-90W/m2，年有效小时数超过3 600 h。对陈岭风塔风力数据的计算分析可以看出，其10 m高度处的年平均风速为3.93m/s，风能密度达到113 W/m2，50 m高度处年平均风速为5.46 m/s；年有效风力时数为6 600 h，年平均风功率密度294 W/m2，具有较高的开发价值。

After exploiting nine weather stations wind speed data from 1971 to 2003 and precise data of wind measurement site Chenling and Bailing from August of 2005 to July of 2006, wind energy characters of Anqing valley along river were researched. The result showed that there were regional differences in wind energy distribution. Wind speed of Anqing valley along river was stable while wind speed in northwest Dabie Mmountain decreased evidently. Wind energy of the whole area was huge. Because of terrain and climate effects, wind energy distributed in west of valley along river. The average wind power density in Wangjiang and Susong was 80 - 90 W/m^2 , and the effective hour was more than 3 600 h. Based on the analysis of wind speed in Chenling, the average wind speed at 10 m height was 3.93 m/s, wind energy density was up to 113 W/m^2 , the average wind speed at 50 m height was 5.46 m/s, the effective hour was 6 600 h, the average wind power density was 294 W/m^2 with high exploitation value.
