The document discusses the Kaptai Hydraulic Power Plant in Bangladesh. It describes how hydropower is a renewable source of energy that uses water from rivers and oceans. The Kaptai Dam was established in 1962 on the Karnaphuli River in Rangamati District. It has a 230 MW hydroelectric power station. The essential parts of a hydroelectric power plant discussed include the dam, water reservoir, control gates, penstock, water turbines, and generators.

2. Hydro Power
1) One of the most widely used renewable source of energy for
generating electricity on large scale basis in hydropower.
2) The power obtained from river, and ocean water is called as
hydropower.
3) Hydropower is the renewable source of energy since water is
available in large quantities from rain, river, and oceans and this
is will be available for unlimited time to come.

Kaptai Dam is the only hydroelectric power station in
Bangladesh.
Kaptai Dam is on the Karnaphuli River In Rangamati
District.
It was established in 1962 near by Karnafuli River.
The generators in the 230 MW Hydroelectric Power
Station.

Essential parts of a Hydro Power Plant

5. 4Hydroelectric Dam

6. The dam is the most important component of
hydroelectric power plant.
The dam is built on a large river that has abundant
quantity of water throughout the year.
It should be built at a location where the height of the
river is sufficient to get the maximum possible potential
energy from water.

 Storage dams
 Diversion dams
 Detention dams
 Overflow dams
 Gravity dams
Component and Working of Hydropower Plant 6

8. 7
The water reservoir is the place behind the dam where water is stored.
The water in the reservoir is located higher than the rest of the dam
structure.
The height of water in the reservoir decides how much potential energy
the water.
The higher the height of water, the more its potential energy.
The height of water in the reservoir is higher than the natural height of
water flowing in the river, so it is considered to have an altered
equilibrium.
Water Reservoir

9. 8
These are the gates built on the inside of the dam.
The water from reservoir is released and controlled
through these gates.
These are called inlet gates because water enters the
power generation unit through these gates.
When the control gates are opened the water flows due
to gravity through the penstock and towards the turbines.
Control gates or intake

10. 9
The penstock is the long pipe or the shaft that carries the
water flowing from the reservoir towards the power
generation unit, comprised of the turbines and generator.
The water in the penstock possesses kinetic energy due
to its motion and potential energy due to its height.
The amount of water flowing through the penstock is
controlled by the control gates.
The penstock

11. 10
Water flowing from the penstock is allowed to enter the
power generation unit, which houses the turbine and the
generator.
When water falls on the blades of the turbine the kinetic
and potential energy of water is converted into the
rotational motion of the blades of the turbine.
The rotating blades causes the shaft of the turbine to
also rotate.
The turbine shaft is enclosed inside the generator.
Water Turbines

12. 11
It is in the generator where the electricity is produced.
The shaft of the water turbine rotates in the generator,
which produces alternating current in the coils of the
generator
