3. INTRODUCTION
Uttar Pradesh Power Corporation Limited (UPPCL) is the company
responsible for electricity transmission and distribution within the
Indian state of Uttar Pradesh .Its chairman is Mr. Alok Kumar.
UPPCL dharpa substation is basically contains two substation one of
220/132 KV & other one of 132/33 KV
Substations:-
• 400kV/220kV substation
• 220kV/132kV substation
•132kV/33kV substation
• 33kV/11kV substation
• 33kV/.4kV substation
4. 220KV SUBSTATION
It is devided into three parts:-
• Panel Section
Control Panel Section
Relay and Protection Panel Section
• Switch Yard
220kV Section
132kV section
33kV section
•Battery Room
5. PANEL SECTION
It has two sections:-
1.Control Panel Section
It contain panels related to controlling of
instruments.Ex:- feeder panel, t/f panel etc.
2.Relay And Protection Panel Section
It contains panels related to relay systems
and protection systems. Ex:- Relay panel,
line protection panel etc.
6. SWITCH YARD
It is the field where components used in controlling supply and
measuring supply(incoming and outgoing) are placed.
Some of these many components are:-
• C.Bs
• Isolators
•C.Ts
• P.Ts
• L.As
• transformers, etc.
9. 220KV SECTION
• It works on 220kV.
• There are two bus bars in which
one is main bus and the other is
transfer bus of 220kV.
• It has seven 220kV incoming
feeders.
•The incoming 220kV line is from
the Northern Grid.
10. 132kV SECTION
• It works on132kV.
• It has two buses i.e. Transfer Bus and
Main Bus.
• 220kV voltage is converted to 132kV
voltage using a 160MVA&200MVA t/f.
• In other words it is 220kV /132kV
substation.
11. 33KV SECTION
• This section works on 33kV.
•It has thirteen feeders of 33 kV.
•132kV/33 kV conversion is done
using 63MVA transformer and two
40MVA transformer.
•In other words it is 132kV / 33kV
substation.
12. BATTERY SECTION
•110 DC SUPPLY REQUIRED FOR OPERATION
OF CIRCUIT BREAKERS.
•55 BATTERIES OF 2V , 300AH (TAURUS-HBL
POWER SYSTEM LTD.){FOR REGULER USE}
•24 BATTERIES OF 2V ,300AH(HBL POWER
SYSTEM LTD.){FOR BACKUP}
•DC SUPPLY REQUIRED FOR METERING
AND PROTECTION DEVICE.
13. COMPONENTS OF SUB-STATION
•RELAY
•CIRCUIT BREAKER
•ISOLATOR
•TRANSFORMER
•CURRENT TRANSFORMER (CT)
•POTENTIAL TRANFORMER (PT)
•CAPACITOR VOLTAGE TRANSFORMER (CVT)
•LIGHTENING ARRESTER( LA )
•FEEDER
•BUS-BAR
•INSULATOR
•CAPACITOR BANK
•WAVE TRAP
14. IMPORTANT TERMS
1.Tripping
• Power goes due to over load . It is for the protection of components.
2.Shut down
•Power is cut due to maintenance in progress. It is done manually.
3.Break down
• Power goes due to any fault in the line. When fault is removed , power
is back.
4.Rosting
•Power is cut deliberately on order of higher authority due to shortage of
power.
15. CONCLUSION
As a profession of engineering we need to have not just theoretical
but practical as well as and so every student is supposed to undergo
practical training session after 3rd year where we have imbibed the
knowledge about transmission, distribution and maintenance with
economical issues related to it. At last I would like to say that
practical training taken at 220 KV substation Dharpa(BSR) has
broadened my knowledge and widened my thinking as a
professional.
