化隆县山地风能资源评估

Wind Energy Resource Assessment of Mountainous Areas in Hualong County

摘要: 根据化隆县现有自动气象观测站，选取山地有自动气象观测站的站点分别为德恒隆乡德一村气象观测站、沙连堡乡政府气象观测站、阿什努乡阿二村气象观测站。利用2023年3月至2025年2月自动气象站测风数据、气压数据、气温数据，根据GB/T 18710-2002风电场风能资源评估方法进行风能的评估，结果表明：德恒隆乡德一村、沙连堡乡政府、阿什努乡阿二村年平均风功率密度在11.5~18.7 w/m²，三站点风功率密度等级为1级。德恒隆乡德一村、沙连堡乡政府2023~2024年四季、全年主导风向均为ESE，风向高度集中。阿什努乡阿二村2023年春夏主ESE、秋冬主WNW，全年主WNW；2024年春夏秋主ESE、冬季主WNW，全年主ESE，ESE风向相对集中。三站点全年有效风速时数在3000 h以下，频率在35%以下，可发电小时数低。

Abstract: Based on the existing automatic meteorological observation stations in Hualong County, three mountainous stations equipped with automatic meteorological equipment were selected, namely Deyi Village Meteorological Station of Dehenglong Township, Shalianbao Township Government Meteorological Station, and A’er Village Meteorological Station of Ashinu Township. Wind, air pressure and temperature data recorded by the automatic weather stations from March 2023 to February 2025 were adopted for wind energy assessment in accordance with the Methods of Wind Farm Wind Energy Resource Assessment (GB/T 18710-2002). The results show that the annual average wind power density ranges from 11.5 W/m² to 18.7 W/m² across the three sites, all classified as Grade 1 in wind power density rating. Deyi Village (Dehenglong Township) and Shalianbao Township Government Station feature ESE as the prevailing wind direction in all four seasons and annually during 2023~2024, with highly concentrated wind directions. At A’er Village (Ashinu Township), ESE prevailed in spring and summer while WNW dominated autumn and winter in 2023, resulting in an annual prevailing direction of WNW. In 2024, ESE prevailed in spring, summer and autumn, and WNW in winter, with ESE as the annual prevailing wind direction and relatively concentrated occurrence. The annual effective wind speed hours at the three stations are less than 3000 hours, corresponding to a frequency below 35%, indicating low hours available for power generation.
