海洋波能发电的现状与前景

State of arts and prospects in the power generation from oceanic wave

波浪能是海洋能源中蕴藏最为丰富的能源之一,也是海洋能利用研究中近期研究最多的海洋能源,其开发利用技术已趋于成熟,正在进入或接近于商业化发展阶段.针对海洋波浪能发电技术的基本原理、能量转换系统等作了全面综述,介绍了国内外海洋波能发电技术的进展和主要波能装置,而其中一些计划的成功实施,有力地推动了波能转换的技术进步及其在世界范围内的竞争力.同时也分析了波浪能研究和利用的发展目标和方向,指出我国波浪能利用对于沿海地区海洋资源的开发和远离大陆海岛的发展有着十分重要的意义.

Wave energy is one of most renewable resource contained in the oceanic energy. This kind of oceanic energy has allured the most attentions in the field of oceanic energy utilization. The exploitation and utilization technology in the field of wave energy has tended to mature. Now it is running into or near commercial exploitation level. The principle of power generation from wave energy and energy conversion systems are introduced in this paper. The development of wave energy conversion technologies and the main wave energy devices in the world are presented. A number of projects have been implemented successfully and they have improved the development of wave conversion technologies and enhanced their competitiveness in the global energy market. In this paper, the development target of wave energy research has been analyzed. It has been discussed that the utilization of wave energy is very important for the exploitation of oceanic resource in the littorals and the development of islands that are far away form the continent.
