2. INTRODUCTION
HYDRO POWER
1) One of the most widely used renewable source of energy for generating
electricity on large scale basis is hydropower
2) The power obtained from river or ocean water is called as hydropower
3) Hydropower is the renewable source of energy since water is available in
large quantities from rain, rivers, and oceans and this is will be available for
unlimited time to come
3. HISTORY
- Nearly 2000 years ago the Greeks used water wheels to grind wheat into
flour
- In the 1700's, hydropower was broadly used for milling of lumber and grain
and for pumping irrigation water
- Appleton, Wisconsin became the first operational hydroelectric generating
station in the United States, in 1882, producing 12.5 kilowatts (kW) of power
- The total electrical capacity generated was equivalent to 250 lights
- The largest and last masonry dam built by the U.S. Bureau of Reclamation
was the Roosevelt Dam in Arizona between 1905-1911; its power output has
increased from 4,500 kW to 36,000 kW
- Still in use today, Niagra Falls was the first hydropower site developed for a
vast quantity of electricity
4. TYPES OF HYDRO POWER PLANT
1) Water wheels
2) Hydro power plants
3) Wave energy from oceans
4) Tidal energy
5) Damless hydro power
Based on Quantity of Water Available
1) Run-off river hydro plants with pond
2) Run-off river hydro plants with pond
3) Reservoir hydroelectric power plants
5. Based on the Head of Water Available
1) Low head hydroelectric power plants
2)Medium head hydroelectric power plants
3) High head hydroelectric power plants
Based on the Nature of Load
1) Base load hydroelectric power plants
2) Peak load hydroelectric power plants
6. PRINCIPLE OF HYDRO POWER PLANT
WATE CYCL
R E
The continuous cycle in which water changes from water vapor in the
atmosphere to liquid water through condensation and precipitation and then
back to water vapor through evaporation, transpiration, and respiration
Water cycle in nature:
Water surface evaporation
Precipitation of clouds
Collected back to the oceans
VAPORATION PRECIPITION RAIN
7. Water cycle in the hydraulic power plant
Water energies: Kinetic energy , Potential energy
PROCESS / STAGES
1) Water in reservoir
2) Fall in turbine blade
3) Shaft rotation
4) Electric generation
5) Flow back of water
8. COMPONENT AND WORKING OF HYDRO POWER PLANT
1) Dam
What is dam
Location
Classification of dams
Storage dams Dam structure and design
Diversion dams
Detention dams
Overflow dams
Rockfill dams
Gravity dams
Gravity dam
9. Storage dams
To impound water
Purpose - Irrigation
- Flood control
- Power generation
Diversion dams
For diversion
To provide sufficient pressure
Detention dams
To Minimize the effect of sudden floods
To trap sediment
Overflow dams
They carry water discharge over their crests
Rockfill dams
Rock instead of earth
Embankment dams hold back water by the force of gravity acting upon
their mass
Gravity dams
Most gravity dams are made from concrete, a mixture of port land cement,
water, and aggregates
They are much thicker at the base than the top
10. 2) Water reservoir
Place behind the dam
Height of water
Potential energy
3) Intake or control gates
Gates inside of the dam.
Inlet gates
4) The penstock
To carries the water
Controlled by the control gates
5) Water turbines
Convert HYDROLIC energy to MECHANICAL energy
6) Generators
Convert MECHANICAL energy in ELECTRICAL energy
11. 7) Transformer
Converts the alternating current to high voltage current.
Two coils: the supply coil and the outlet coil.
Voltage required for various applications is 110V or 230V.
Numbers of turns in outlet coil are double of supply coil, the voltage
produced is also double.
8) Tailrace
Pipeline to drain the water
The potential energy of water in the tailrace has been used to generate
electricity

14. Structure
The Hirakud Dam is a composite structure of earth, concrete and masonry
Ten km north of Sambalpur, it is the longest major earthen dam in the world
The main dam has an overall length of 4.8 km spanning between two
hills; the Lamdungri on the left and the Chandili Dunguri on the right.
It also forms the biggest artificial lake in Asia, with a
reservoir holding 743 km² at full capacity, with a shoreline of
over 640 km..
People affected from the Dam Construction
Nearly 1.5 lakh people got affected by the Hirakud
project.Nearly 22,000 family were displaced under the Hirakud
dam project,
an amount of Rs 12 crores was provided for payment of
compensation to the affected people
