2. INTRODUCTION--
 In India 65% of total power is generated by the Thermal
Power Stations.
 The West Bengal Power Development Corporation
Limited (WBPDCL) is a company owned by the Government of West
Bengal with the goal to carry on the business of thermal power
generation in the state of West Bengal, India. The thermal power plants
under WBPDCL are
in Kolaghat, Bakreswar, Sagardighi, Santaldih,and Bandel.
 Kolaghat Thermal Power Station have a total installed capacity of 1260
MW (6x210 MW).
 Bakreswar Thermal Power Station have a total installed capacity of
1050 MW (5x210 MW).
 Sagardighi Thermal Power Project have a total installed capacity of
1,600 MW (2x300 MW, 2x500 MW

8. PLCC(POWER LINE CARRIER COMMUNICATION)
Use of PLCC in modern electrical power
system is mainly
for telemetry and telecontrol. Tele means
remote. Telemetry refers to science of
measurement from remote location
For large power system power line carrier
communication is used for data transmission
as well as protection of transmission lines.
Carrier current has a frequency range of 30
to 200 kHz in USA and 80 to 500 kHz in UK

9. PLC(PROGRAMMABLE LOGIC CONTROL)
 A programmable logic
controller (PLC),
or programmable
controller is an
industrial digital
computer which has
been ruggedised and
adapted for the control of
manufacturing
processes, such
as assembly lines,
or robotic devices, or any
activity that requires high
reliability control and
ease of programming and
process fault diagnosis.

10. RELAY (PROTECTIVE)
 Role of protective relay in
power plant is to reduce
the damage to the
equipment in case of
electrical failure.In high
voltage power
plant systems, this concept
can be done by providing
separate voltage or current,
separate tripping battery
sources or separate trip
coils on the circuit breaker

11. STEP UP TRANSFORMER
LARGE AMOUNTS OF ELECTRIC ENERGY ARE GENERATED AT POWER PLANTS WHICH ARE USUALLY LOCATED
LONG DISTANCES FROM USERS. BECAUSE OF RESISTANCE IN TRANSMISSION WIRES, SOME OF THIS POWER IS
LOST IN MOVING THE POWER THROUGH THE WIRES. THERE ARE TWO CHOICES TO DECREASING OR LIMITING
THE POWER LOST IN THE WIRES. STEP UP TRANSFORMER PICTUREONE, MAKE THE WIRE A LARGER
DIAMETER OR TWO INCREASE THE VOLTAGE PUSHING THE ELECTRICITY THROUGH THE WIRE. INCREASING THE
SIZE OF WIRE IS TOO EXPENSIVE SO THE COMMON METHOD OF LIMITING LINE LOSSES IS TO RAISE THE
VOLTAGE.
STEP-UP TRANSFORMERS PERFORM THIS TASK AND ARE GENERALLY LOCATED AT THE GENERATING STATION.
THEY GET THEIR NAME BECAUSE THEY LITERALLY "STEP-UP" OR INCREASE THE VOLTAGE LEVEL FROM THAT
WHICH IT IS GENERATED AT TO A SUFFICIENT LEVEL FOR TRANSPORTING LONG DISTANCES.

12. SWITCHYARD
 It is a switching station
which has the following
credits :(i) Main
link between
Generating plant
and Transmissionsystem,w
hich has a large influence
on the security of thesupply.
 (ii) Step-up and/or Step-
down the voltage
levelsdepending
uponthe Network Node.
 (iii) Switching ON/OFF Rea
ctive Power Control devices
,whichhas effect on Quality
of power.

13. SWITCHYARD EQUIPMENTS
 Equipments commonly found in switchyard :
 1.Lightening arrestor
 2.Current transformer
 3.Voltage transformer
 4.Power transformers / I.C.T.
 5.Bus bar and clamp fittings
 6.Support structure
 7.Isolators
 8.Circuit Breake
 r9.Wave traps
 10.Earthing switch

14. GRID
 Electrical power travels from the power plant to your house
through an amazing system called the power distribution grid.
The grid is quite public — if you live in a suburban or rural area,
chances are it is right out in the open for all to see. It is so public,
in fact, that you probably don't even notice it anymore.
Your brainlikely ignores all of the power lines because it has seen
them so often.
