Depending on the form of energy:
1. Kinetic energy production: use the flow speed of rising and falling water to directly impact the turbine to produce electricity;
2. Potential energy production: construction of barriers in bays or estuaries. Tidal dams use the difference in water levels between the inside and outside of the dam during high and low tides to generate electricity.
According to the development method:
1. Single-shore unidirectional type: generates electricity only at low tide;
2. type: high and low tide Generate electricity every time;
3. Double bank unidirectional type: can produce electricity continuously
4. .
3.2 Principle of electricity production
Build a tidal dam in a bay or estuary. There is a lock below the tidal dam, leaving a channel of water, and awater wheel is installed in. the channel to produce electricity.
At high tide, the lock is open and the hydroelectric generation unit turns to produce electricity. When the sea water level reaches its maximum, the sluice is closed after the ebb, the sluice is opened and the water is released. flows from the reservoir to produce electricity again.
