摘要
海洋波浪能量是风能、太阳能等环境能源中能量密度最大的一类能源,分布非常广泛。但海洋波能开发和利用还相对滞后,传统的波能采集装置由于存在转换机械结构复杂、转换效率低及耐冲击腐蚀能力差等缺点,实现较为困难。一种以提高转换效率、稳定可靠为目的的能量采集装置——直接式波能采集装置近年来越来越受到重视,成为该领域研究的热点。本文详细总结了直接式波浪能量采集的总体情况、特点、主要结构类型及其充电控制策略,论述了波能发电的电能管理系统,并对直接式波浪能量采集系统的发展趋势进行了展望。
Ocean wave energy,which is much rich on the earth,is one of the highest density energy among all renewable energies such as wind and solar energy. However,traditional ocean energy harvesters are unpractical because of their complicated conversion structures,low transmission efficiency,and weak anti-corrosion and anti-shock capacities. Thus,a wave energy harvesting device for promoting the tran-sferring efficiency,reliability and stability,which is called direct energy harvester,is more and more emphasized and has become a research focus. This paper summarizes in detail the research status,characteristics,main classes,charging control strategies and power management systems of direct ocean wave harvesters. Moreover,the development tendencies of direct ocean wave harvesters are prospected.
