摘要
波浪的原始观测数据量大,难以进行直观分析,为此建立了海洋波浪信息资源计算机评估系统,并利用此系统详细评估了浙江嵊山海域的波浪资源。结果表明:该海域波功率为0.5～8.8kW/m,2kW/m的频率分布为60%左右,因而在该海区可采用波能发电作为能源供给的一种辅助方式。分析风浪向波功率的频率分布,对于波力发电装置的浪向选择有一定指导意义。在夏季,55%以上波功率频率分布与偏南方向有关;在秋冬季,60%以上波功率频率分布与偏北方向有关。该海区波浪周期集中分布于4～5s,波高集中分布于1.2～1.5m,这种集中分布的特点对波能装置的设计和波能的有效利用非常有利。
A computer software system was established, which can manage, calculate and analyze the data from the ocean wave observing records. Using this system, wave energy resource of Sheng- shan sea area, Zhejiang Province was evaluated in detail. Wave power density typically ranges from 0.5 to 8.8 kW/m, the frequency of 2 kW/m is about 60%, and as a result wave power still makes a substantial contribution to these locations energy supply. The analysis of the wave direc- tion frequency distribution of wave power density, has the instruction significance regarding the design of the wave power generation device. During the summer, the southerly direction frequency distribution of wave power density is above 55%; However during the autumn and winter, the northern direction frequency distribution is above 60%. Wave period in the sea area focuses on the distribution of 4-5 s, wave height focuses on 1.2-1.5 m. Those terms are significant properties for the design of wave power generation device and the effective use of wave energy.
