【摘要】 利用广西玉林天堂顶区域内的1座测风塔资料,依据GB/T 18710—2002风电场风能资源评估方法对该区域的风能进行评估测算。结果表明:该区域风能资源等级为4级,风能资源好;可发电小时数较高,风向稳定,风能较为集中,有效风速频率高,风速和风能分布对称;风速、风功率密度年内、日内变化均较大;区域空气密度中等,风垂直切变基本符合幂指数规律。更多还原

【Abstract】 Based on the data of an anemometer tower in Tiantangding region of Yulin, the wind energy resource was measured and calculated according to GB/T 18710—2002 Methodology of Wind Energy Resource Assessment for Wind Farm in this paper. The results showed that its wind energy standard reached the forth level, and wind energy resource was abundant; The time that can generate electricity was plenty, the wind directions were stable, and the wind energy resources were concentrated; Frequency of the effective wind speeds were high, and the speed and energy resources distributed symmetrically; The daily and annual variations of wind speeds and wind power density were large; The density of air was medium, and vertical wind shear is basically in accordance with the power law.更多还原
