摘要
利用松门山-吉山风场70m测风塔2009年4月～2010年3月测风资料及都昌气象站近20a平均风速资料,对松门山-吉山地区的风能资源参数进行了详细计算和分析,并对松门山-吉山风能资源开发利用进行了可行性分析评价。结果表明：松门山-吉山测风塔各高度层全年盛行偏北风,主导风向为N和NNE,主导风向风能占总风能的90%左右。30~70m高度湍流强度和风切变指数较小。50、70m高度处风能资源有效小时百分率为73﹪~76%,风功率密度分别为302.8、326.7W/m2,风能资源等级为3级,属风能资源较丰富区,具备风电开发价值。
After exploiting the wind data of 70 m height wind measurement site in Songmenshan-Jishan wind farm and the average wind speed data of Duchang Weather Station for nearly 20 years, wind energy characters of Songmenshan-Jishan area were detailed calculated and analyzed, meanwhile, the feasibility of the wind re source development in this area was evaluated. The result showed that： At all th e levels, northerly winds prevailing throughout the year, the dominant wind dire ctions are N and NNE, in these two directions, the wind energy accounted for abo ut 90% of the total wind energy. At the height from 30 to 70 meters, the turbule nce intensity and wind shear is small. The average wind power at 50 and 70 meter s are 302.8 and 326.7 w/m2, and the percentages of effective hours are 73 to 76% , in this area,the wind energy resources is abundant. In the end, this area is valuable to develop wind power.
