全球海域风能资源评估及等级区划

Wind Energy Resources Assessment in Global Ocean

利用1988年1月至2009年12月具有高精度、长时间序列的CCMP(Cross-Calibrated,Multi-Platform)风场,对全球海域的风能资源进行评估。综合考虑风能密度大小、能级频率、大风频率、有效风速、风能密度的稳定性等各方面,对风能资源进行系统性研究,并对全球海域的风能资源进行区划,为海上风力发电等风能资源的开发利用提供科学依据。研究发现全球海域蕴藏着丰富的风能资源,大部分海域为风能资源的富集区,尤其富集在南北半球西风带,风能资源的贫乏区主要分布于赤道附近和两极零星海域,可利用区和较丰富区主要分布于低纬度海域、太平洋东部中低纬近岸海域、两极大部分海域。

In this paper, wind energy resources in global ocean from January 1988 to December 2009 were analyzed by using high resolution CCMP （Cross-Calibrated, Multi-Platform） wind field. By synthetically considering the size of wind energy density, the frequency of energy level, scale frequency, effective wind speed and the stability of energy density, the resources of wind energy in global ocean were analyzed arid zonation was conducted, providing guidance to wind power plant location. Results show that the global ocean is rich in wind energy, with rich areas lo- cated in the waters of westerlies of the Northern Hemisphere and the Southern Hemisphere, poor areas mainly distributed in the waters nearby the equator and scattered sectors of the two poles, and the sub-rich area located in the waters of low latitude, eastern sector of the low latitude in the Pacific Ocean, and most waters of the two poles.
