摘要
文章以某超高海拔风电场示范工程测风塔和测光塔实测数据为基础,提出利用辐射量与风速之间的相关关系进行超高海拔地区负切变现象主要成因的探究方法,发现该类地区负切变现象主要成因为大气稳定性,而不是地形因素。大气稳定性对负切变的影响主要是通过太阳辐射量影响气流运动实现,风切变大小基本与与辐射量高低成反比关系,为超高海拔地区风电开发工程设计以及风电机组技术研发等都提供了重要借鉴。
Based on the measured data of wind tower and light tower of a super high altitude wind farm demonstration project, this paper proposes a method for exploring the main causes of negative shear in ultra-high altitude areas by using the correlation between radiation quantity and wind speed. It is found that the negative shear phenomenon in this type of area is mainly due to atmospheric stability, not topographical factors. The influence of atmospheric stability on negative shear is mainly achieved by the influence of solar radiation on air movement.The size of wind shear is inversely proportional to the radiation level, which provides an important reference for the design of wind power development engineering and the development of wind turbine technology in ultra-high altitude areas.
