南海海域波浪能资源模拟评估

Simulative evaluation of wave energy resources in the South China Sea

为了大范围评估波浪能资源,文章通过WAVEWATCH-Ⅲ模式结合高精度的CCMP风场资料对南海海域四季的波浪能资源进行定量计算和定性分析,分析结果表明:南海海域的波浪能分布表现出明显的空间和季节分布特性,大值区主要集中在中北部海域、东沙群岛和台湾岛邻近海域,而低值区主要分布在北部湾、曾母暗沙以及泰国湾周边海域;在冬季,南海海域的波浪能流密度及其稳定性方面均比其他季节有明显优势,且冬季的平均波浪能有效储量的总体水平表现为全年最高;南海北部、台湾岛东南部海域以及东沙群岛附近海域的波浪能资源丰富,是资源优势区域,适宜波浪能开发。

In order to large-scale assess wave energy resources, the seasonal wave energy resources of the South China Sea was calculated quantitatively and analyzed qualitatively by WAVEWATCH-Ⅲ model and high-precision CCMP. The results are as follow:The distribution of wave energy in the South China Sea shows obvious spatial and seasonal characteristics;The large value areas are mainly concentrated in the central and northern waters, the waters near Dongsha Islands and Taiwan Island, while the low value areas were mainly distributed in Beibu Gulf,Zengmu Reef and the surrounding waters of the Gulf of Thailand. The wave power density and its stability in winter have obvious advantages over those in other seasons;The overall level of effective reserve of wave energy in that seaon was the highest in the whole year. The wave energy resources are abundant in the northen of South China Sea, the southeastern waters of Taiwan Island and the waters around Donsha Islands, which are advantageous areas for the development of wave energy.
