National Thermal Power Corporation Ltd. is one of the
Maharatna companies Incorporated in 1975.
 NTPC is India’s largest power generation companies in
India.
It is the sixth largest thermal power generating company in
the world.
 NTPC has 15-coal based and 7-gas based power stations.
Presently,it has an installed capacity of 44,304 MW.
RSTPS (RAMAGUNDAM SUPER THERMAL
POWER STATION).
 RSTPS was incorpoated in the year 1975.
 RSTPS installed capaity is 2600MW.
 The RSTPS consists of 3 stages STAGE-I : 3X200
MW. STAGE-II : 3X500 MW. STAGE-III : 1X500
MW.
 The area of plant is 10,000 acres.
 The water is supplied through SRI PADA YELLAMPALLI
Reservoir.
P O W E R P L A N T REQUIREMENTS.
 Coal/fuel availability: RSTPS obtains the coal from South Godavari coal
field of Singareni collieries for stage I & II and Korba coal fields of SECL
for stage III.
 Water requirement: SRI PADA YELLAMPALLI RESERVOIR.
 Ash disposal: Ash pod at Kundanapally ,5KM away from theplant.
 Evacuvation of power: The power generated from station is evacuated
through 9 no’s 400kV / 3 no’s of 220kV/ 2no’s of 132kV overhead
transmission lines.
 Distribution of power: The power generated is distributed toAndhra
pradesh,Telangana,Tamilnadu,Kerala and Pondicherry.
INTRODUCTIONTO CHP.
In Thermal power plant coal is used as fuel.
NTPC is maintaining MGR(merry go round) system to transport
the coal.
Here wagons are unloaded in two ways:
i. Wagon tippler.
ii. Track hoper.
The coal is unloaded from a box type wagon by tilting
150deg angle.
 In this the wagons are bottom opentype.
 Toopen and to close we use aircompressors.
CRUSHER HOUSE : Crusher house is used
to crush the coal to a size of 20mm.
The house consists of crusher blades.
CONVEYOR PROTECTION SYSTEM
1.Pull cord switch : Pull cord switch is
used as a safety switch to stop the
conveyor emergency.
2.Belt sway switch : The switch allows smooth running of
conveyor and protects it from overswaying due to uneven
loading of material.
3 . Chute block switch : Chute block switch is
used to monitor the chute
jamming in hopper & give early
warning of Belt Damage.
4 . Field & desk emergency push button : Emergency
push button is an electronic switch used to stop the
conveyor.
INTERLOCKSYSTEMS
Magnetic separator :
Metal detector
:
STACKER RECLAIMER is a large machine
used to handle bulk material.
Generally it is rated in tonnes per hour
(tph).
It can usually move in 2 directions: horizontal
and vertical.
There are 3 STACKER RECLAIMERS in RSTPS SR-
1,SR-2,SR-3.
Bucket wheels are used for digging the coal back and
sending it to the boiler when coal is required.

The target of NTPC is to achieve
75,000 MW by 2017.
In CHP most of the induction motors
are of squirrelcage motors.
In CHP fluid coupling of motors is
employed.
NTPC Ramagundam also has 10 MW
SOLAR POWER PLANT.
