GOVERNMENT ENGINEERING COLLEGE ,AJMER
Guided By :- Presented By :-
Mr. K.G SHARMA ABHISHEK MATHUR
Associate professor VII th semester
Electrical Branch

2. KOTA THERMAL POWER STATION

3. REASON FOR CHOOSING KOTA FOR THERMAL
PLANT SETUP
 Availability of large amount of clean cooling water
required for the station.
 Location of station on broad gauge main Delhi- Mumbai
Railway line
 Concentration of load in Kota city and Kota region.
 Constant power supply.
 Proximity to M.P. Coal fields.
 Transmission and Grid substation are quite nearer to the
site.

4. INTRODUCTION
KSTPS is first coal based power plant in Rajasthan.
It is located ideally on the left bank of CHAMBAL
River at the upstream of KOTA BARRAGE.
Its first unit of capacity 110 MW is synchronized on 17
jan 1983.
It is one of highest power generating plant with
installed capacity of 1240 MW.

5. DESIGN

Stage V
Stage I
Unit 1 – 110 MW Unit 7 – 195 MW
Unit 2 – 110 MW
Stage II Stage III Stage IV
Unit 3 – 210 MW
Unit 5 – 210 MW Unit 6 – 195 MW
Unit 4 – 210 MW
110 + 110 + 210 + 210 + 210 + 195 +195 = 1240 MW

• GENERAL LAYOUT
• COAL HANDLING PLANT
• PROCESS OF STEAM GENERATION
• TURBINE
• GENERATOR
• SWITCHYARD

7. PLANT OVERVIEW

8. COAL HANDLING PLANT
• Is called the HEART of thermal
power plant because it provided the
fuel for combustion in boiler.
• The coal is brought to the KSTPS
from BHARAT COAL LTD.
• There are 14 tracks for
transportation.
• Everyday 3- 4 trains of coal are
unloaded, each train consists 58
wagons.
• Coal is unloaded from wagons by
means of WAGON TRIPPLER

10. PROCESS OF STEAM GENERATION
K.S.T.P.S

11. TURBINE
• Turbine is a machine in which a shaft is rotated
steadily by impact of steam it converts heat
energy into mechanical energy.

13. TURBO GENERATOR
Designed for continuous operation at the rated output.
Directly coupled with steam turbine, rotated at high speed
of 3000 RPM.
Two major parts:-
STATOR AND ROTOR
Major parts of stator are Major parts of rotor are
Stator frame Rotor frame
Stator core Rotor Windings
Stator bars
Stator windings

14. SWITCHYARD
The 220 KV Switch yard is the main part of the KTPS
it has two buses arrangement with a bus coupled breaker.
There are 11 feeders connected at 220 KV switchyard

15. Main parts of Switchyard
• CIRCUIT BREAKER
• ISOLATOR
• CURRENT TRANSFORMER
• POTENTIAL TRANSFORMER
• LIGHTNING ARRESTOR

16. CIRCUIT BREAKER
 Circuit breaker is basically a mechanical device used
to make or break an electrical circuit under normal &
abnormal condition.
 A circuit breaker is switched on or off under load
conditions an arc is produced in between the breaker
contacts.
 This arc produced between the breaker contacts is
quenching by some suitable medium.

17. TYPES OF CIRCUITS BREAKER
MINIMUM OIL CIRCUIT BREAKER SF6 CIRCUIT BREAKER
In M.O.C.B separating contact of the In SF6 separating contact of the
breakers are made to separate within breakers are made to separate within
an insulating oil. SF6 material.

18. ISOLATORS & ARRESTORS
• Isolators are device which disconnect the instruments
from power supply, the isolators provided at 220 KV
switchyard are motor operated.
• Lightening Arresters are used in switchyard for preventing
from Lightening phenomena and are installed at entrance
of switchyard.

19. CURRENT TRANSFORMER
• Current transformers are provided for measuring
and protection. All Current Transformers at 220
KV switchyard are BHEL manufactured .
• Designed to provide a current in its secondary coil
proportional to current flowing in its primary coil.
• Primary winding consists of very few turns.
• Secondary winding consists of large no. of turns
• Current to be measured is passes through
primary winding.

20. POTENTIAL TRANSFORMER
• Used for the measurement of high voltages.
• Primary winding is connected to voltage to be
measured.
• Voltmeter is connected across the secondary
winding.
