| 摘 要： | 波浪能是一种重要的海洋可再生能源,开发利用波浪能资源可以有效地缓解常规能源短缺所带来的能源问题,波浪能资源分布状况的可靠评估是开发利用波浪能资源的前提条件。利用ECMWF ERA-Interim 1992-2011年0.75°×0.75°的较高精度的海浪场数据,计算了OE-W01区块(中国渤海、黄海及东海的部分区域)的波浪能流密度以及波能资源的可用度频率、富集度频率、变化指数等评价指标。对该海域的波浪能资源进行了全面评估。研究发现:渤海海域波浪能资源呈现非常明显的季节分布特征,秋冬季较丰富、春夏季较贫乏,秋冬季为波浪能资源的主要利用期,波浪能资源的相对富集区集中在渤海海峡以及渤海和黄海相连通的区域;黄海海域(包括东海部分海域)波浪能资源也呈现季节分布特征,与渤海不同,该海域90%的区域年平均波浪能流密度均在2kW/m以上,波浪能资源的可用范围较大,时间较长,波浪能资源的富集区集中在长江口东部海域以及舟山群岛东南部海域。在此基础上确定了波浪能资源的重点开发利用区,可为该海域的波浪能资源的开发利用提供参考依据。

| Abstract: | Wave energy is an important marine renewable energy. The exploitation and utilization of wave energy resources can solve energy problems arising because of a lack of conventional energy. It is a precondition for the development of wave energy resources to make reliable estimates of the distribution of wave energy resources. Based on 1992-2011 ECMWF ERA-Interim 0.75° × 0.75° reanalysis high-precision wave field data, we calculated wave power density and evaluation indices such as usable level frequency, rich level frequency and variability index of wave energy resources for OE-W01 area (including the Bohai Sea, Yellow Sea and part of the East China Sea). We found an obvious seasonal distribution characteristic for wave energy in the Bohai Sea: wave energy resources are richer in winter and autumn and poorer in spring and summer. Therefore, winter and autumn should be the main periods of utilization. Relatively rich areas of wave energy are located in the Bohai Strait, adjacent areas, and the Yellowe Sea. In the Yellow Sea (including the part of the East China Sea), there is a seasonal distribution characteristic for wave energy resources and different from the Bohai Sea, 90% of the Yellow Sea has an annual average wave power above 2kW/m. The range of usable wave energy resources is large and the time of availability is long. Relatively rich areas of wave energy are located in the east sea area of Changjiang Estuary and the eastsouth sea area of Zhoushan Islands. Some important areas for wave energy resource exploitation are discussed, and these data provide reference points for wave energy resource exploitation. |
