1). The project was proposed By the Central Electricity Authority In 1973.

2). In 1975, project was revised by the Consultant Thermal Design

Organization.

3). The planning commission cleared the project report in Sept., 1976.

4). The first 2x110 MW units were manufactured by BHEL, Hyderabad

in 1st

stage.

5). First estimated cost at that time was 143 crores rupees.



LOCATION

Ideally on the left

bank of Chambal

River at Up

Stream of Kota

1). The thermal power station burns the fuel and use the heat to raise the

steam.

2). Heat from the coal is absorbed by kilometers long tubes in boiler walls by

³Boiler Feed Water´ and transferred to the turbine blades rotating them.

3). When turbine rotates, the rotor housed inside the stator turns with it.

4). Electricity is produced by the movement of magnetic field created by

rotor.

5). This electricity passes to the transformer which steps up the voltage for

effective transmission.

6). The used steam is changed back into water in the condenser for reuse.



1). 220 KV SYSTEM :-

i). CIRCUIT BREAKERS

ii). ISOLATOR

iii). CIRCUIT TRANSFORMER

220 KV System :-

Each of the generator is connected to this system through a step up of

125 MVA 240/ 11 KV yard generator transformer. There are two step

down transformer each feeding 6.6 KV system (Station Switchyard ).

Four feeder take off from 220 switch yard two to SAKATPURA ,GSS and

other to HEERAPURA,Jaipur GSS.



220 KV System

CIRCUIT BREAKERS

Minimum oil circuit

breaker of BHEL make

is used.

rated for 245 KW, 2500

A and 13400 MVA.

ISOLATOR

Provided in 220KV switchyard and are motor operated

Triple pole double breaker type, L&T make, rated for

245 KV and 1250 A.

CIRCUIT TRANSFORMER

Provided for measuring

and protection.

They are BHEL make,

single phase, oil filled

nitrogen sealed outdoor

type.

5). Waveform



Pr inciple of ope r ation

1). Working depend on Dynamic action of steam

2). Steam is passed through passage of nozzle

3). Heat energy is converted into mechanical kinetc energy

4). The turbine suffers a change of momentum and rotates
