广东海陵岛风能资源高分辨率数值模拟研究

　　5 结论
　　本文采用WRF/CALMET 模式系统对广东海陵岛进行水平分辨率200m×200m 的高分辨率风能数值模拟，得到了海陵岛风能资源分布与变化规律以及风能资源开发潜力。通过与岛上7 个测风塔观测资料的对比分析，证明WRF/CALMET 模式系统用于山地风电场的风能资源评估是可行的。如果将WRF/CALMET 模式系统用于近海风能资源数值模拟，还需考虑海浪引起的海面粗糙度随风速的变化。
　　但是地形动力诊断的方法还不足以很好的模拟陡峭地形风能资源分布，此时基于Navier-Stokes 方程非线性求解的大气边界层模式则有明显优势。但相比之下，WRF/CALMET模式系统比WRF/WT 计算量小、计算范围大，一般的山地风电场风能资源评估可采用WRF/CALMET 模式系统，对于特别复杂的地形可采用大气边界层模式进行补充。
