廣東海陵島風(fēng)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(duì)廣東海陵島進(jìn)行水平分辨率200m×200m 的高分辨率風(fēng)能數(shù)值模擬，得到了海陵島風(fēng)能資源分布與變化規(guī)律以及風(fēng)能資源開發(fā)潛力。通過與島上7 個(gè)測(cè)風(fēng)塔觀測(cè)資料的對(duì)比分析，證明WRF/CALMET 模式系統(tǒng)用于山地風(fēng)電場(chǎng)的風(fēng)能資源評(píng)估是可行的。如果將WRF/CALMET 模式系統(tǒng)用于近海風(fēng)能資源數(shù)值模擬，還需考慮海浪引起的海面粗糙度隨風(fēng)速的變化。
　　但是地形動(dòng)力診斷的方法還不足以很好的模擬陡峭地形風(fēng)能資源分布，此時(shí)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(shì)。但相比之下，WRF/CALMET模式系統(tǒng)比WRF/WT 計(jì)算量小、計(jì)算范圍大，一般的山地風(fēng)電場(chǎng)風(fēng)能資源評(píng)估可采用WRF/CALMET 模式系統(tǒng)，對(duì)于特別復(fù)雜的地形可采用大氣邊界層模式進(jìn)行補(bǔ)充。
