海洋能指蕴含在海水中的各种可再生能源。海洋通过各种物理过程接收、储存和散发能量,这些能量以潮汐能、波浪能、温度差能、盐差能、海流能等形式存在于海洋之中。潮汐能是现阶段应用最多的一种海洋能,利用潮汐发电需要建立水库,涨潮时使海水进入水库,落潮时利用水库与海平面的高度差推动水轮机发电。它不能连续发电,因此又称为单程式潮汐式电站。随着技术的进步,人们设计了双库单向潮汐式电站,这种电站建有两个相 Ocean energy refers to a variety of renewable energies contained in seawater. The oceans receive, store and distribute energy through a variety of physical processes that exist in the oceans and seas in the form of tidal energy, wave energy, temperature difference energy, salt differential energy, and sea currents. Tidal energy is the most widely used marine energy at this stage. Tidal power generation requires the establishment of reservoirs. At high tide, seawater enters the reservoir. At low tide, the altitude difference between reservoir and sea level is used to promote hydroelectric power generation. It can not generate electricity continuously, so it is also called a one-way tidal power plant. With the progress of technology, people design a double-storey one-way tidal power plant, this power plant has two phases
