选择四川省凉山州某高海拔山地作为研究区域,采集并处理了该区域 1 个气象站 1981~2015 年的统计数据以及该区域内 4 个测风塔 1 年的实测数据,开展风能资源评估.研究发现,该区域局部地形复杂,海拔在 3530~3950 m,面积约为 40 km2,西南风影响较大,风能资源较丰富.通过频率分析发现该区域风向稳定,WSW方向风速和风能最大.计算该区域风功率密度为 2 级,属 IEC II/III类风电场.另外,研究表明该区域 50 年一遇最大风速低于 IEC标准值,但湍流指数达到 IEC B类,风电机组疲劳载荷影响需要评估.该研究为高原山地复杂地形区域的风电场开发提供了科学的风能资源评估方法,也为该区域的风电场设计提出了建议.
Assessment of Wind Energy Resource in High-altitude Complicated Mountainous Terrain
This study performed wind energy resource potential assessment of a high-altitude mountainous area in Liangs-han Prefecture,Sichuan Province as the research area by collecting and processing the statistical data from a meteorologi-cal station from 1981 to 2015 and the measured data from 4 wind towers for 1 year.It was found that the local topography of the area is complex with an altitude of 3530~3950 meters and an area of about 40 square kilometers.It is greatly influ-enced by the southwest wind and the wind energy resources are relatively abundant.Frequency analysis revealed that the wind direction in this area is stable with the maximum wind speed and wind energy in the WSW direction.The wind power density level of the area is calculated to be Class 2,which belongs to IEC Wind Turbine Class II/III.In addition,the study showed that the 50-year extreme maximum wind speed in the area is lower than the IEC standard value,but the turbu-lence intensity reaches IEC Class B,and the fatigue load impact on wind turbines needs assessment.This study provides a scientific wind energy resource assessment method for wind farm development in complex topography highland mountain-ous areas and also proposes suggestions for the wind farm design.
