摘要

斯里兰卡西北沿海地区被认为是风力发电潜力巨大的地区。优越的地理位置和地形条件对较高的风力发电量产生了影响。目前,斯里兰卡政府正在全国推广风力发电。本研究旨在评估气候变化对马纳尔地区风力发电的影响。在马纳尔收集的风数据用于开发该地区的广义风地图集。要为该地区测量的风数据生成风图,需要地形和高程的详细信息。为了评估马纳尔风力发电的成本,在考虑地面粗糙度的影响下,通过在选定的风力发电机位置叠加广义风图,对合适的商用风力发电机进行了微定位。通过考虑风力机特性和预测地点风势来评估风力发电。利用一般环流模式(GCM)和区域气候降尺度模式(RCD)预测了该地区的风速变化趋势,并确定了正趋势。并对风电场的微静尾效应进行了计算。该研究以可行的风能发电成本验证了Mannar风电开发目标的潜力。

Impact of climate change on wind energy generation in Mannar-Sri Lanka
North Western coastal area of Sri Lanka is identified as a region with substantial wind power potential. Favorable geographical location and the terrain conditions have effected for higher wind power generation. Presently, the Sri Lankan government is promoting wind power generation in the country. This study is intended to evaluate impact of climate change on wind power generation in Mannar area. Wind data collected in Mannar was used to develop generalized wind atlas for the region. To generate wind atlas for the region measured wind data, topography and elevation details are required. To evaluate cost of wind energy generation in Mannar, suitable commercial wind turbines were micro-sitted by superimposing generalized wind atlas on selected wind turbine locations with the effect of ground roughness. Wind power generation was evaluated by considering wind turbine characteristics and predicted wind potential of the locations. General Circulation Models (GCM) and Regional Climate Downscaling (RCD) model was predicted wind speed change trend in the region and positive trend was identified. In the micro-sitting wake effect in wind farms were also calculated. This study validated the potential of wind power development target in Mannar with viable cost of wind energy generation.
