ACKNOWLEDGEMENT

We are gladly & thankful to Director as well as Principal, Dr. V.N

Jasani and Head of the Departments Prof. M. M. Baraiya and our

faculties who give us a great guidance regarding training and

instruct us the importance of training in electrical field. So we

decided to take visit in 220KV Substation, Shapur

We are especially thankful to respected authority of GETCO,

Junagadh division because they granted us permission for taking

visit and assistant engineers of Shapur Substation who gave the

proper guidance to students and gave practical based approach

learning to students.

GENERAL INFORMATION

Gujarat Energy Transmission Corporation Limited (GETCO) was

set up in May 1999 and is registered under the Companies Act,

1956. The Company was promoted by erstwhile Gujarat Electricity

Board (GEB) as its wholly owned subsidiary in the context of

liberalization and as a part of efforts towards restructuring of the

Power Sector. The company is now a subsidiary of Gujarat

UrjaVikas Nigam, the successor company to the GEB.

An electrical substation is a subsidiary station of an

electricity generation, transmission and distribution system where

voltage is transformed from high to low or the reverse using

transformers. Electric power may flow through several substations

between generating plant and consumer, and may be changed in

voltage in several steps.

A substation that has a step-up transformer increases the

voltage while decreasing the current, while a step-down transformer

decreases the voltage while increasing the current for domestic and

commercial distribution.

PURPOSE OF VISIT

Our main purpose for this visit is to be familiar with industrial

environment and to get practical knowledge of electrical power

transmission and distribution .one other purpose is how we can

decide our 8-semester project on industrial based.

Students of 6th semester Electrical Engineering will get the idea of

electrical power transmission and distribution. Students will also get

familiar with Transformer maintenance, circuit breaker,

Transformer isolator, bus bar, Protective relays, Lightening

arresters, Load break switches, Scada system, Current and voltage

Transformer And Battery room.

WHAT WE LEARN?

On 9th jan.,2016 (Saturday) at 09:45 am we reached at Shapur Sub

Station.

When We Reached,we saw the mainly 3 substation are there

1) 220/132 KV

2) 220/66 KV

3) 220/66 KV

At the begining one of the assistant engineer explained all the

essential component of the 220KV substation and explained one line

diagram of shapursubstation.In addition they explained about

SCADA (Supervisory Control And Data Acquisition) and various

programming done in control room.

After explanation of control room,the assistant engineer

gives one helmet for our head protection and we reach directly in

yard.

We saw in yard, many Electrical equipment are there.(Like,

lightening arrestor, Isolator, Circuit Breaker, Bundled Conductor,

Transformer, Busbar, Current And Voltage Transformer, Wave trap)

one assistant engineer gives totally details of all the equipment.

1) Lightening arrestor (LA) The work of LA is break (Cut) the on load line.The LA is operated

on SCADA based (automatically) and manually.

2) Circuit Breaker (CB)

The circuit breaker is a proctiondevice.generally the CB is

operate below condition.

Break the circuit automatic or manual under normal

condition.

Break the circuit when circuit is fault condition.

Make a circuit either remote control or manual under fault

condition.

In this substation SF6 circuit breaker are used.(other CB are

also used like, Air blast CB , vacuum CB, oil CB)

Some of the outstanding properties of SF6 making it desirable to

using power applications are:

1. High dielectric strength

2. Unique arc-quenching ability

3. Excellent thermal stability

4. Good thermal conductivity

3) Conductor The conductor are used In transfer power from one place to other

place.generally the material used in conductor are aluminum, copper

etc…

4) Transformer The work of transformer is voltage step or down without change in

frequency.Generallytransformers ratting in KVA or MVA.But this

substation 100 MVA transformer are used.

5) Current Transformer (CT) “Current transformer is a device which use the measure on load

current”. The Current transformer are connected in series.

6) Potential transformer (PT) “The potential transformer is a device which use the measure bus-

bar voltage. The potential transformer are connected in parallel.

7) Wave Trap

The function of wave trap is communication one substation to other

substation with the help of frequency.

8) Battery room There are three panel of battery source one is for PLCC, it is 48v,

two panels are 220v, and it is for relay operation and many more

application. These batteries are charged when AC supply is ON.

CONCLUSION

From this visit, we got the information and practical knowledge about Power

Distribution and Transmission. Student got the knowledge about different

protection devices used in substation. They got the idea how to read the one

line diagram of power substation using different symbols used in diagram.

Student cleared out practical knowledge of transformer as how it step down

voltage 220 KV to 132 KV.They also got knowledge about new SCADA

based system as you can operate substation by manually or by command

from computer using SCADA system and PLC programming. About 4

students were benefited from this visit as they got chance to discussion with

assistant engineers working at Substation.
