以潮汐水位变化作为动力进行的发电称为潮汐发电,也称潮力发电,或海潮发电。 所谓潮汐现象是指大洋水体受太阳和月亮的吸引而发生的水位有规律的变化。这种变化,在大洋中只有几十公分,但是,当潮波传到岸边的时候,特别是在某些海湾和河口等处,由于海底地形和海岸轮廓等因素的影响,水位变化的时间和幅度极为复杂。有些地区,高潮和低潮水位差达几米至十几米。例如,大西洋沿岸美国和加拿大交界处的芬迪湾,潮差最大可达18米。名闻世 Power generation using tidal water level changes as a motivation is called tidal power generation, also called tidal power generation, or tidal power generation. The so-called tidal phenomenon refers to the ocean water body by the sun and the moon attracted the occurrence of a regular change of water level. This change, only a few tens of centimeters in the ocean, but when the tide waves spread to the shore, especially in some bays and estuaries, due to the impact of seafloor topography and coastal profile and other factors, the water level change time And the magnitude is extremely complicated. In some areas, the difference between high tide and low tide reaches several meters to ten meters. For example, up to 18 meters of tidal range at the Gulf of Fendi at the junction of the United States and Canada on the Atlantic coast. The name of the world
