垂直坡度地形风电场的风资源特性研究

为了准确评估垂直坡度地形风电场的风资源特性,选取了风电场内两个具有代表性的位置进行现场测风,对测风数据进行综合对比分析表明,如果来流风向上存在垂直或近似垂直的坡度地形,会对坡顶边缘位置的风速和湍流产生不利影响,而随着向腹地的深入,不利影响将逐渐减弱.因此,机位选址时,在主风向上应尽量避免选择垂直坡度地形的坡顶边缘位置,...

On the Characteristics of Wind Power Resources in Wind Farms with Vertical Slope Terrain

In order to accurately evaluate the characteristics of wind power resources in wind farms with vertical slope terrain,in-situ measurement is carried out in two representative locations in a wind farm.Comparison and analysis of the measurement data show that the vertical or nearly vertical slope in the wind inflow direction will impose adverse effects in terms of the wind speed and turbulence for the position at the edge of the slope top,and the adverse effects will gradually weaken with the increasing distance from the edge to the hinterland.Thus,top edge of vertical slopes should be avoided in wind turbine site selection as far as possible in the main wind flow direction,so as to keep the wind turbine out of the safety impact caused by excessive inflow angle.
