风向变化对高海拔山地风电场发电效益的影响

摘要

Wind direction difference in different area in a wind farm causes that data from anemometer tower is unrepresentative. Especially, in mountain platform wind farm, wind forming condition complexity due to the micro topography leads to the wind direction variety. Data deviation from the main anemometer tower often affects the generation and the economics of a wind turbine. In this paper, it is analyzed that wind direction variation due to the micro topography in a wind farm leads to generation reduction and affects the economics as well. To avoid of generation reduction due to wind direction difference in mountain area fringe, strengthening measuring wind in this area for wind turbines layout is proposed.%本文通过某山地风电场由于微观地形对风电场局部风向的改变，导致该区域风机发电量的减少，影响风电场经济性的问题，提出了在高山台地风电场布机应加强对场址边缘区域的测风观测，避免由于微地形风向差异的影响导致风机发电量下降的措施及建议。
