| 中文摘要: |
| 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。喀拉布拉镇站和公安农场站的风向主要以东风和南风为主，肖尔布拉克沟站的风向则以南风为主。测风塔4302的风速随着高度变化不明显。测风塔4301-4306均存在南风和北风，但各风向占比有一定差异。随高度升高，测风塔南风风向呈现出东南转西南的趋势。（2）ERA5-Land资料不能很好地再现研究区域风场变化。（3）数值模拟的风场变化具有一定山谷风特征。夜间的风向以东南风为主，白天则低海拔河谷地带风吹向山顶，北部谷风逐渐主导东北风向。20时，风电场区域主要以西北风为主。 |

| Based on the observation data of meteorological stations and anemometer tower around the wind power plant in Xinyuan County, the reanalysis data of ERA5-Land and the numerical simulation results, the structural characteristics of the wind power plant in Xinyuan County were analyzed. The results show that： (1) The hourly wind speed of 10m at the weather stations around the wind power plant was lower in the morning and evening, and higher at noon. The wind direction at Kalabra Town Station and Public Security Farm station was mainly east and south wind, while the wind direction at Shoerbrak Ditch station was mainly south wind. The wind speed of tower 4302 did not change significantly with the height. Wind anemometer tower 4301-4306 had south wind and north wind, but the proportion of each wind direction was different. With the increase of height, the south wind direction of the tower showed a trend of southeast to southwest. (2) ERA5-Land data cannot reproduce the wind field changes in the study area well. (3) The wind field variation of numerical simulation had certain valley wind characteristics. The wind direction at night was mainly from the south to the east, during the day, the low-elevation valley wind blows to the mountain top, and the northern valley wind gradually dominated the northeast. At 20:00, the wind farm area was mainly northwest wind. |
