廣東海陵島風能資源高分辨率數(shù)值模擬研究

　　5 結(jié)論
　　本文采用WRF/CALMET 模式系統(tǒng)對廣東海陵島進行水平分辨率200m×200m 的高分辨率風能數(shù)值模擬，得到了海陵島風能資源分布與變化規(guī)律以及風能資源開發(fā)潛力。通過與島上7 個測風塔觀測資料的對比分析，證明WRF/CALMET 模式系統(tǒng)用于山地風電場的風能資源評估是可行的。如果將WRF/CALMET 模式系統(tǒng)用于近海風能資源數(shù)值模擬，還需考慮海浪引起的海面粗糙度隨風速的變化。
　　但是地形動力診斷的方法還不足以很好的模擬陡峭地形風能資源分布，此時基于Navier-Stokes 方程非線性求解的大氣邊界層模式則有明顯優(yōu)勢。但相比之下，WRF/CALMET模式系統(tǒng)比WRF/WT 計算量小、計算范圍大，一般的山地風電場風能資源評估可采用WRF/CALMET 模式系統(tǒng)，對于特別復(fù)雜的地形可采用大氣邊界層模式進行補充。
