福建沿海海域波浪能资源分析与评价

采用波浪模拟的方法,较准确计算得出福建沿海海域波浪能资源分布状况,并给出相应的分析和综合评价.主要结论如下:(1)福建沿海海域波浪能平均密度为2.6～7.3 kW/m,波浪能资源储量为2 210.45 MW,在我国沿海海域仅次于台湾和广东,是波浪能开发利用可以优先考虑的海区之一.(2)福建沿海海域波浪能资源储量的70%分布于平潭岛以北海域,其值达1 512.49 MW.其中,尤以北礵地区值最大,为378.80 MW.(3)以年平均波高为指标,福建沿海海域中东山区段为三类区,其他区段均为一类区和二类区,具有良好的开发前景.(4)福建沿海海域波浪能具有波功率密度低、资源分布广泛且不均匀、波功率密度随季节变化、能量具有多向性等分布特点.(5)基于福建波浪能的开发与利用现状,建议应优先着眼于解决边远海岛等特殊场所的用电问题.

An evaluation and analysis of the ocean wave energy resource in nearshore waters of Fujian

By a simulation of ocean wave energy in nearshore waters of Fujian with the third-generation wave model SWAN and with relative analysis and estimation. The conclusions are obtained as follows. （ 1 ） The ocean wave ener- gy＇ s average density range 2.6 to 7.3 kW/m in nearshore waters of Fujian, and the ocean wave energy reserve is 2 210.45 MW,which is next to that of Guangdong and Taiwan in China. （2）More than 70% of the ocean energy reserve distribute in waters in the north of Pingtan island where it is 1 512.49 MW,and in Beishuang section it reaches the highest （378.80 MW）. （3）With values of the average ocean wavehigh of year, Dongshan section is listed at the third class, other sections are first and second class. （4）The ocean wave energy reserve in nearshore waters of Fujian has 4 characters, i. e. lower power density, wide but uneven distribution, seasonal variations and multiple directions. （5）Based on the status of ocean energy exploitation and utilization, it is suggested that the power supply problem be solved by the priority of remote islands.
