利用新源县风电场周边气象站及测风塔观测资料、ERA5-Land再分析资料和数值模拟结果,分析了新源县风电场的风场结构特征.结果表明:(1)风电场周边气象站的逐小时 10m风速均呈现出早晚偏低、中午偏高的变化规律,且风向以东风和南风为主.测风塔的观测风向以南风和北风为主,随高度升高,南风呈现向西南偏转的趋势.(2)ERA5-Land资料与观测资料存在较大差异,不能很好地再现研究区域风场变化.(3)2022 年 7 月 23-24 日风场的数值模拟结果与观测风场有较好的一致性,且模拟风场呈现出显著的山谷风特征.其中,研究区域夜间的风向以东南风为主,白天以东北风为主,傍晚以西北风为主.
Structure Characteristics of Wind Field in Wind Farm under Complex Terrain in Xinyuan
Based on the observation data of meteorological stations and anemometer tower around the wind farm in Xinyuan county,combining the ERA5-Land reanalysis and the numerical simulation results,the structural characteristics of the wind filed in wind farm of Xinyuan county were analyzed.The results showed that:(1)The hourly wind speeds of 10 m height of the weather stations around the wind farm were lower in the morning and evening,and higher at noon,and the wind directions were mainly east and south wind.However,the wind directions of the wind anemometer towers were mainly south and north wind,and the south wind gradually turned into southwest wind with the increase of height.(2)There were obvious differences between ERA5-Land reanalysis and observation data,and ERA5-Land reanalysis could not well reproduce the wind field changes in the study area.(3)The numerical simulation results of the wind field from July 23 to 24,2022 could well reproduce the observed wind field,and the simulated wind field presented significantly valley wind characteristics during.Among them,the wind direction was mainly southeast wind at night,northeast wind during the day,and northwest wind in the evening in the study area.
