摘要
在进行风电场项目前期开发与风资源评估时,当缺少测风资料的低风速区域、分散式风电开发以及复杂山地复杂环境项目上,获取高分辨率风资源已逐步开始使用中尺度与微尺度嵌套结合的降尺度模拟技术势在必行。为此,结合实际工程案例,对中尺度与微尺度CFD技术结合的具体方式进行研究,比较了"中尺度区间"模式与"虚拟点"模式之间的模拟结果差异,总结分析了两种模式的应用及适用性。
For wind power projects which are located in lower wind speed areas or complex mountainous environment,or distributed wind power development projects,downscaling techniques that combine the mesoscale and microscale models are gradually implemented to carry out the high resolution wind resource assessment. With the discussion on practical examples,the downscaling techniques that combines the mesoscale and microscale computational fluid dynamics（ CFD）models are studied. Specifically,the simulation results from the ＂mesoscale interval ＂mode and the ＂virtual point ＂mode are compared. The applicability of these two modes are summarized.
