Construction and Working of Tidal Power Plant
The Extraction of potential energy Involves
building a barrage. The barrage traps a water level inside a basin. Head is
created when the water level outside of to basin changes relative to the water level inside. The head is used to
drive turbines. In any design this leads to a decrease of tidal range. Inside
the basin, implying a reduced transfer of water between the basin and the sea.
This reduced transfer of water accounts foot the energy
produced by the scheme.
The dam have
large gates in it and for storing water in the storage basin the gates are
opened at the time of high tide and after storing Water the gates are closed.
After the tide has receded, the water is allowed to flow back to the ocean
through water turbine. Thus the tidal energy stored at Height can be utilized to
drive a turbine coupled to an electric generator, which generates Electrical power.
Buy using reversible water turbine the turbine can run Continuously both during
high tide and low tide. The Principle of operation is il
lustrated.
