Tidal power, also called tidal energy, is a form of hydro power that converts the energy of tides into useful forms of power, mainly electricity.
In the estuary or tidal estuary, there are two fluctuations in the sea or the river every day, and the tide is a natural phenomenon, which provides a convenient for human's navigation, fishing and salt.. This phenomenon is mainly caused by the tide force of the moon and the sun and the effect of the earth rotation.. When the tide, a lot of water surge, has great momentum; at the same time, the water level gradually increased, the kinetic energy into potential energy. At low tide, the water rushing to gradually decline in water level, potential energy into kinetic energy. The kinetic energy and potential energy of sea water during the movement are collectively called tidal energy.. Tide is a kind of reserves great and inexhaustible, without exploitation and transportation, clean pollution-free renewable energy. Construction of tidal power station, do not need to immigration, non flooded land, no environmental pollution, can also be combined with the reclamation of tidal power development, aquatic and marine chemical comprehensive utilization project.

The main utilization of tidal energy is tidal power.. Tidal power and ordinary water generation principle is similar to and through the reservoir. At high tide the water stored in the reservoir, stored in the form of potential energy, then release water at low tide, the gap between high and low tide levels, promote the turbine rotation, driven by a generator. Difference lies in the different sea water and river water, the accumulation of water drop small, but flow is larger, and is intermittent, and tidal power turbine structure to suitable for the characteristics of low head and large discharge.
Tidal power is a kind of hydroelectric power. In the conditions of the bay or sense of tide port construction of dams, gates and plant, and tidal power extremely rapid technical progress, has developed a variety of tidal energy is changed into mechanical energy of mechanical equipment, such as propeller turbine, axial flow turbine, open circulation type hydraulic machine, Japan began to use satellites to provide a flow of information. The use of tidal power generation matures, has entered a practical stage.
