    摘 要:以云南分布式发电 (DG) 山地风电场为研究对象,应用改进的 Park 尾流模型,综合考虑不同大气稳定度等级下,测风塔模拟计算风轮廓线与实际测量风轮廓线的差值和趋势,选取最适宜风电场的大气稳定度等级。使用 Meteodyn_WT 软件对最适宜大气稳定度等级下的平均风速、风能密度和发电量进行计算,将计算结果与采用中性大气稳定度的计算结果进行对比,结果发现,大气稳定度对山地风电场的各项性能指标都具有一定影响。

    Abstract: The paper takes Yunnan Distributed Generation(DG) mountain wind farm as the research object, adopts the improved Park wake model to study the difference and trend between the simulated wind profile obtained from wind tower and actual measured wind profile under circumstances of various levels of atmospheric stability to select the most appropriate atmospheric stability level. Meteodyn_WT software is employed to calculate average wind speed, wind energy density and power generation which are most suitable for atmospheric stability.Then, the relevant results calculated by neutral atmospheric stability are compared with the above results, and it is found that atmospheric stability has some effects on performance indexes of mountain wind farms.
    Key words: atmospheric stability; distributed generation; mountain wind farm; power generation
