风力发电对局地气候的潜在影响分析

Analysis of Potential Impacts of Wind Power Generation on Local Climate

作为实现能源结构调整及节能减排的重要发电技术之一,风力发电在有效利用风能的同时,风力机的大规模运行也可能会对局地大气的自然循环产生影响。在综述国内外有关风电场可能存在的气候效应的相关研究的基础上,具体分析了包括地表粗糙度、地面附近湍流热交换、边界层高度等环境物理参数受到风电场运行的潜在影响,得出了大型风电场对局地气候存在潜在影响的结论。

Wind power generation, which is one of the important technologies to achieve energy structure adjustment, energy saving and emission reduction, can make effective utilization of the wind power. However, the operation of wind turbine may have impacts on natural atmospheric circulation. The existing researches about potential climatic effect of wind farms are firstly reviewed. Then, some physical paramelers of the environment related to climate, which may be affected by the wind farms, including surface roughness, turbulent heat transport near surface and height of atmospheric boundary layer are concretely analyzed. The result illustrates that large scale wind farm may have potential impact on the local climate.
