3. INTRODUCTION
• Rana Pratap Sagar Dam is built on Chambal River.
• There are 7 feeders connected to the Power Stations.
• There are 4 units of generation.
• Each unit generate 11KV, 43MW.
• It operates only in months from August to April
• The generation is decided by the RLDC(Regional Load Dispatch Centre) at
Jaipur.
• General Electrical, Canada is the company of manufacturing most of the
equipments installed in the Power Station.
NOTE:- Pictures Provided in PPT does not belong to the Power Plant

4. Classification of Hydro electric power station.
• CLASSIFICATION BASED ON HEAD.
A. High head plant ( < 300 m.)
B. Medium head plant. (60m to 300 m.)
C. Low head plant. ( > 60m.)
• CLASSIFICATION BASED ON WATER CONDITION.
A. Flow of water plant.
B. Storage of water plant.
C. Pump storage water plant.

7. Element of Hydro power station,
1. Reservoir.
2. Catchments area.
3. Dam.
4. Spill ways.
5. SCADA Screen.
6. Fore bay or Intake.
7. Tunnel.
8. Penstock or pipe line.
9. Surge tank.
10. Draft tube.
11. Tail race.
12. Turbine.

8. How Hydro Electric Power Plant Works!
• Water from the reservoir flows
due to gravity to drive the
turbine.
• Turbine is connected to a
generator.
• Power generated is
transmitted over power lines.

11. Spill Way
During the lifetime of a dam different flow
conditions will be experienced and a dam must be
able to safely accommodate high floods that can
exceed normal flow conditions in the river. For
this reason, carefully passages are corporate in the
dams as a part of structure. These passages are
known as spillways.
Function of Spill Way
Function of spillway is to discharge
the excess amount of water during
floods and keep the level of water to
the head of reservoir.

 There are 4 Power Transformers in which only one has buchholz relay and other have PVR for
protection
 Transformers have both oil forced and water forced cooling system
 Oil is pumped into veins within water for extra cooling by two motors.

16. Image of installed Guide Bearing
 There are two type bearings used in the plant
1. Thrust Bearing:-
1. Alternator is placed over this bearing so
the weight of alternator comes over the
bearing i.e. 418 tons.
2. It is combined by 16 curved parts where
each part have 30 springs for sharing load
and vibrations.
3. It is placed horizontally along with
alternator
2. Guide Bearing:-
1. It is placed along with alternator
2. It allows 8 thou* space for alternator
vibrations
3. It is combined with 16 parts. * 1 thou = thousand part of an inch

19. Advantage of Hydro power station.
1.The plant is simple in construction ,robust and required
low maintenance.
2.It can be put in the service instantly.
3.It can respond to changing loads without any difficulty.
4.There are no stand by losses.
5.The running charges are very small.
6.No fuels is burnt.
7.The plant is quite neat and clean.
8.The water after running the turbine can be used for
irrigation and other purpose.

20. Disadvantage of Hydro power station.
1. The capital cost of generators, civil engineering work etc is
high.
2. Long dry seasons may effect the delivery of power.
3. The loss of land under the reservoir.
4. Interference with the transport of sediment by the dam.
5. Problems associated with the reservoir.
i. Climatic and seismic effects.
ii. Impact on aquatic ecosystems, flora and fauna.

21. Conclusion
I would like to conclude that a practical training has been very useful. To learn
about practical and theoretical differences while working on large machines and
real life problems. It also help to get ready for any problem that may occur at
any place and solving it as soon as possible.
