To build a tidal power station, you need to build a dam in a bay or a tidal estuary to form a reservoir, and place a hydroelectric generator set in or next to the dam to make use of the rise and fall of seawater levels when the tide rises and falls. When passing through the water turbine, it drives the water turbine generator set to generate electricity. From an energy perspective, it uses the potential energy and kinetic energy of seawater to convert it into electrical energy through a hydroelectric generator. Therefore, it must first be close to the sea, have tidal energy, and also have hardware facilities such as reservoirs and wheels. Generally in areas with relatively abundant tidal energy.
First, the amplitude of the tide must be large, at least a few meters.
Second, the topography of the coast must be able to store a large amount of seawater and allow for civil construction projects.
Tidal energy is ocean energy in the form of potential energy, which refers to the potential energy of water formed by the rise and fall of seawater. The tidal phenomenon of rising and falling sea water is caused by the movement of the earth and celestial bodies and the interaction between them. In the ocean, the moon's gravity raises the water levels on the lunar and farside sides of the Earth.
