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.

TURBINE


11/22

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.


12/22

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.


15/22

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.


16/22

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.


17/22

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.

COOLING TOWER


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 ).


21/22

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
