This presentation summarizes tidal power plants and how they generate electricity. Tidal power plants harness the energy from rising and falling tides using structures like tidal barrages, tidal fences, and tidal turbines. Tidal barrages are dams built across rivers with tunnels that allow water powered by tides to flow through and spin turbines. Tidal turbines resemble underwater wind turbines lined up in tidal areas to capture tidal flows. When tides rise and fall, they cause turbines to rotate and generate electricity. While tidal power is a clean source that produces no emissions, tidal power plants can be expensive to construct and only generate electricity for around 10 hours per day when tides are moving in or out.
2. Objective
The main purpose of tidal is to generate
electricity for tidal power plants.
Mostly other energy sources is use like
coal,water,nuclear reactor from which we
generate electrical energy but here I give
extra information how we can generate
electrical energy from tidal.
4. Tidal Energy
Tidal energy is energy that is
created by the rise and fall of
the earth’s sea level. The
amount of energy that is
produced is determined by
how high or low the tide rises.
5. Three Ways Tidal Energy
Created
Tidal barrages :-A tidal barrage
basically a huge dam that is built across
a river.Tunnels are build through out
the dam
Tidal fences :-tidal fences block a
channel, forcing water to go
through it and turning
its turbines to generate electricity.
Tidal turbines :-tidal turbines are
the latest water power technology
used in tidal areas. They look like
wind turbines that are lined
together underwater. They are
used to capture strong tidal flows
6. Electricity Produced From
Tidal
In first picture when the
tidal goes up due to
which the force come on
turbine and turbine will
be rotate and generate
electricity
Now in second case
when the tide goes out
then so it rotate the
turbine again and thus it
generate electricity
7. Main Components of a Tidal
Energy Plants
A tidal containment wall
The piles
The panels
Locking posts
Turbines
8. Construct of Tidal Plant
Tidal plant construct with the sea side
Not on the island or desert
9. Countries Which Use Tidal
Energy
Norway (the world’s first floating tidal power demonstration plant,
Morild 2, with a capacity of 5 GWh or 5 million kWh)
Italy,Bolzano (50 tidal power plants each with an installed power is
20MW)
Korea (building a power plant with a capacity of 240-260 mega
watt)
In France capable to produce (240MW)
10. Advantages
The energy produced is clean
and non polluting. .
There is no carbon dioxide or
any other by-products
released. It produces no
greenhouse gases or other
waste.
It reduce on the burning fossil
fuels.
It needs no fuel.
It produces electricity
reliably.
Not expensive to maintain.
11. Disadvantages
You will need to find a way
to connect the electricity to
the grid.
Only provides power for
around 10 hours each day,
when the tide is actually
moving in or out.
Cannot be used in land.
Expensive to construct.
