金昌地区风能资源分布特征及开发潜力分析

利用2005～2009年间金昌境内4个测风点的实测资料和气象站相应时段的气象资料,对风能资源评估参数进行了计算,初步分析了金昌地区的风能资源特征及开发潜力。结果表明:芨岭滩和南山坡在10 m高度处年平均有效风能密度分别为148.4和129.8W/m2,年有效风累积小时数均超过5 000 h,风能资源较为丰富。风速随高度的升高而增大,50 m高度处的年平均有效风能密度较10 m高处多70%。上述两地具有较为明显开发价值,适合建设大型风电场。

Analysis on Wind Energy Resource Distribution Characteristics and Development Potential in Jinchang District

By using data from four wind measuring sites and meteorological stations in Jinchang during 2005-2009,the evaluating parameters of wind energy resource were calculated,the wind resources characteristics and development potential in Jinchang District were analyzed.The results showed that:the annual average effective wind energy densities of Jilingtan and Nanshanpo at 10 m are 148.4,129.8 W/m2,respectively.The annual effective wind accumulated hours are over 5 000 h,the wind energy resource is abundant.The wind speed increased with height improved,the annual average effective wind energy density at 50 m height is 70 % more than that at 10 m.The above two sites both have obvious development value,which are suitable for building large-scale wind power field.
