山东半岛周边近岸海域波浪能开发潜力研究

WAVE ENERGY DEVELOPMENT POTENTIAL ASSESSMENT IN NEARSHORE SEA AREA AROUND SHANDONG PENINSULA

利用近20年的ERA-Interim再分析海浪场数据,对山东半岛周边近岸海域波浪能开发潜力进行评估,重点研究优势区域重点单站和波浪能装置有关的指标。结果表明:山东半岛周边近岸海域波浪能资源开发潜力较高的优势区域位于威海东北部近岸海域、荣成东部和东南部近岸海域。优势区域重点单站波浪能的集中度较好,各季节主波功率密度的方向集中在北向上;对总能量有突出贡献的波高和波周期范围大致相同,为Hs:0~3.5 m,Te:0~8 s。Wave Star是目前最适合于重点单站波浪能开发的装置,但其能量利用率仅约为6.2%,并非最理想的选择,还需研发效率更高的波浪能装置。

Based on ERA-Interim reanalysis wave field data in recent 20 years,the wave energy resource development potential in near shore sea area around Shandong peninsula is assessed.Some indexes related to the key single-station in the wave energy advantageous areas and wave energy devices are studied emphatically.The results show that the high potential areas of wave energy around Shandong peninsula are located in the nearshore waters of the northeast of the Weihai city and the east and southeast of the Rongcheng city.In nearshore key locations in high potential areas,the concentration ratio of wave energy are very good and the direction of dominant wave power density are focused on north direction in various seasons.The significant wave height and wave period which have main contribution to total wave energy are similar,Hs is 0-3.5m and Te is 0-8s.Wave Star is the most suitable wave energy converter for wave energy development in key single-stations,but its energy utilization rate is only about 6.2% and is not the most ideal choice.It is also necessary to develop more efficient wave energy device.
