On what principle is tidal energy production based? Solve.

The main method of using tidal energy is tidal power generation. Two physical conditions must be met to use tidal power generation: first, the tidal amplitude must be large, at least a few meters. civil construction projects. The working principle of tidal power generation is similar to that of general hydroelectric generation, that is, a dam is built at the mouth of a river or bay to form a natural reservoir and that the hydroelectric generator is installed in the dam. Tidal power stations can be single or double reservoirs. It can be seen from Figure 1 that a single-reservoir tidal power plant builds only one dam and one reservoir. The old single-reservoir tidal power plant allows seawater to enter the reservoir at high tide and uses the tidal differencee between the reservoir and the sea surface to power the hydroelectric generator at low tide. It cannot produce electricity continuously, so it is also called single-tank, single-stage tidal power plant. The new single-reservoir tidal power plant takes advantage of the special reservoir design and sluice function to generate electricity at high tide and operate at ebb tide. It cannot produce electricity only at flat tide when the water reaches the inner and outer level. the tank is the same. This type of power plant is called two-stage single-tank tidal power station, which greatly improves the utilization rate of tidal power.
