ACKNOWLEDGEMETAny attempt at any level cannot be satisfactorily
completed without the support and guidance of learned
people. I would like to express my immense gratitude to
K.B.U.N.L. Muzaffarpur,Bihar and Project Manager Mr.
A.K.Banerji and Mr. Vijay Pratap for their constant
support and motivation that has encouraged me to comeup with this project.
Finally; I would like to express my thanks to all of
the technical & non technical persons for the co-operation & valuable guidance during my training
period.

An Overview
NTPC
NTPC was set up in 7th November 1975, the
NAVRATNA power giant today generatesmore than one fourth of the total power in
the country, ranked 5th largest power
generating utility in the world.

INTRODUCTION ABOUT THE PLANT
KBUNL (Kanti Bijlee Utpadan Nigam Limited) which
was formerly known as Vaishali Power Generating
Company Ltd(VPGCL) is situated in Kanti which is 12
km away from main town Muzaffarpur, Bihar.
It is totally coal fired Thermal power station.
There are two units of each 110MW installed
capacity.

WORKING PRINCIPLEThe working principle of thermal power plant is based on Rankin cycle.
A central steam station basically works on the Rankin cycle. Steam is
produced in the boiler , is expanded in the prime mover (Turbine) and
is condensed in a condenser to be fed into the boiIer.
PROCESS OF GENERATION OF ELECTRICITYMTPS Kanti is a Thermal Power Plant. The functioning of every
Thermal power plant is based on following process:-
1. Coal To Steam
2. Steam To Mechanical power
3. Power Generation, Transmission & Distribution.

Types Of Turbine
1. HP Turbine
HP turbine is a single flow design with 8 stages of blading.HP
turbine is double shell construction comprising inner and
outer casing .
2. IP Turbine
Intermediate pressure turbine is a double flow design with
seven stages of blading on either side of central steam inlet.
3. LP Turbine
L.P Turbine is a double flow design with six stages in each of
its front and rear flow paths.

BOILERBoiler is a closed vessel in which water is converted into
steam.
There are two types of boilers
1. Fire Tube Boiler
2. Water Tube Boiler

GENERATOR

14/22
A generator consists of rotor which consists of
carbon brushes. The rotor rotates at 3000rpm in caseof any fault if production of plants stops then we
have bearing motor which rotates shaft of turbine
continuously and rotor at 65rpm. This is because if
shaft doesnt rotates then due to load it may bend.
As generator produces 110MW or generates 11kv
output. The output of generator is step up to 220kv
by using step up transformer or generating
transformer. Three phase is fed to station
transformer.

Transmission
The KBUNL has capacity to generate 220MW ofelectricity but only one unit is working and the second
unit is under R&M process. We are generating 90Mw
out of 110MW and giving to the substation.
The transmission is done through three phase, double
circuit system with the help of transformer, we are
converting 11kv to 220kv and fed to substation. It is
then step down to 132kv and feeded to BSEB and
local areas.

Equipments used in transmission of power:-
1. Sub-station
A. Control Room
B. Switch YardSub-Station:-
It is the place where power is changed, step down or step up and
transmitted to other places. It consists of various protection equipments,
switching circuits etc.
A. Control Room:-It is the brain of any sub-station. All the necessary steps about the
transmission, protection, charging etc. are carried out in the control
room.
B. Switch yard:-It is systematic arrangement of various components, where all the
machines or equipments are connected with each other, looping, step
down, step up of transmission line are
done here only.

Transformer:-
A transformer is an electrical device which
works on the principle of mutual induction. Theautotransformer used in power station. It has
three windings primary, secondary and tertiary.
The 220kv voltage is fed as input to primary bystep down 132kv fed MTPS as input.

20/22
Cooling water circuitA large quantity of cooling water is
required to condense the steam in
condenser and in maintaining a low
pressure in it. Cooling water may be taken
from the upper side of the river and after
passing through condenser (where it isheated ).

FAN
A fan is a device by which the air is made to flow at required
velocity and pressure in a defined path imparting K.E of its
impellers to air/flue gases. This pressure boost is used to create a
draught in the air and flue gases system.
Types Of Fan:-
1. P.A Fan
2. F.D Fan
3. I.D Fan
