2. INTRODUCTION OF KSTPS
 In kota super thermal power
station electricity is generated.
 The project was proposed by
central electric authorithy of
india in April,1973.
The project was revised in
1975 and approved in sep.,1976
At first two units are installed
each producing 110MW of
power

3. DESIGNING OF UNITS
Unit-1 110MW
Unit-2 110MW
Unit-3 210MW
Unit-4 210MW
Unit-5 210MW
Unit-6 195MW
Unit-7 195MW

4. SITE SELECTION OF
POWER PLANT
• Availability of water
• Nearness to load centre
• Distance from populated area
• Availability of coal
• Transportation facility
• Ash disposal

5. CONTENTS OF KSTPS

6. PROCESS

7. ADVANTAGE OF PLANT
 Fuel used is cheaper
 Less space is required
 Cheaper in production cost
 Cheaper in initial cost compared to other
generating stations

8. DISADVANTAGE OF
THERMAL PLANT
• High maintenance and operating cost
• Requirement of large water quantity
• Handling of coal and disposal of Ash
• Pollutes the atmosphere
• Costlier in running cost
• Efficiency falls below 75% of full load

9. INDUCTION MOTOR

10. INTRODUCTION OF INDUCTION MOTOR
• An induction or
asynchronous motor
is a type of Ac motor
where power is
supplied to the rotor
by means of
electromagnetic
induction and
generate rotation
rather than by slip-
rings and
commutators as in
slip-ring Ac motors.

11. CONSTRUCTION OF INDUCTION
MOTER
• An induction motor consists of two parts
1. stator: when supplied with a 3-phase
currents, produce a magnetic flux. which is of a
constant magnitude but which revolves at a
synchronous speed.This revolving magnetic flux
induces an e.m.f. in the rotor by mutual induction
2. rotor:it has two types .
2.1 squirrel-cage rotor: squirrel-cage induction
motors employ squirrel-cage rotor.
2.2 phase-wound rotor : motors employing this type
of rotor ,such as ‘slip-ring’ motors or ‘wound’
motor

12. DIFFERENCE b/w SQUIRREL-CAGE
ROTOR&PHASE-WOUND ROTOR
SQUIRREL PHASE-WOUND
1. Rotor consists of a 1 Rotor consists of 3-phase
cylindrical double-layer distributed
laminated core with windings consisting of coils
parallel slots carrying the as used in alternator
rotor conductors. 2 Rotor is wound 3-phase
2. Each bar is placed in each even when the stator is
slot. wound 2-phase
3. Rotor bars are permanently 3 Requires additional
short-circuited on resistance in the rotor
themselves. 4 Under normal condition,
4. motor Run quietly slip- rings are
5. Reduces the locking automatically short-
tendency of the rotor circuited

13. PRINCIPLE OF OPERATION
• Depends on electromagnetic
induction
• A 3-Phase winding energized
from a 3-phase supply. A
rotating magnetic field set-
up around the stator at a
synchronous speed
• Rotating magnetic field
passes the air gap and acts
the rotor conductor
• e.m.f. induced in rotor
conductor and current start
flowing in rotor conductor
and mechanical force on
rotor produces a torque

14. TYPES OF INDUCTION MOTOR
• Rotary induction motor
• Linear induction motor
a. Stator is a straight track and rotor moves in track
when a current to stator
• Power input induction motor
a. Single-phase induction motor
i. not self-starting
ii. Split-phase motor, capacitor motor,shaded-pole
motor
b. Two-phase induction motor
c. three-phase induction motor
i. Stator & rotor
ii. Self-starting torque

15. Starting method of
induction motor
• Direct on line starting
• Stator resistance starting
• Auto transformer starting
• Star-delta starting

16. Direct on line starting
• Motor is connected
directly to 3-phase
supply and starting
current high 4 to 10
times the full load
current.

17. Stator resistance starting
External resistances
are connected in
Series with each
phase of stator
winding during
starting.

18. Auto-transformer
starting
Aim of this to a
reduced supply
at starting. As
the motor picks
up sufficient
speed.

19. Star-delta starting
star connection during
starting gives
Stator-phase voltage
is 1/sqr3 times
The line voltage and
staring torque
is 1/3 times the delta
value

20. ADVANTAGE DISADVANTAGE
1 Simple and extremely 1 Constant speed motor
rugged, almost 2 Starting torque is inferior
unbreakable construction to d.c. shunt motor
2 Low cost and very reliable 3 Speed decreases as the
3 Sufficiently high efficiency load increases unlike
4 No brushes are needed synchronous motor
5 No need of extra starting 4 High cost of Speed
motor control auxiliaries
6 Minimum maintenance 5 Low starting torque
7 Self starting torque

21. APPLICATION OF
INDUCTION MOTOR
• Used in industry with VFD’S Technology.
• VFD’S gives following points.
• Speed variation.
• High starting torque requirements.
• Low starting current requirements.
• High efficiency at low speed.
• In real time application, Domestic fans &
refrigerators.
