This internship report summarizes a summer internship at the Gandhinagar Thermal Power Station in Gujarat, India. The internship included visits to four sections: the coal plant electrical maintenance department, the testing department, the switchyard, and the electrical maintenance department. The interns learned about the coal handling and storage process, various types of electrical protection systems, equipment testing procedures, and components of the power plant such as the boiler and turbines. Overall, the internship provided hands-on experience in key areas of power generation and an opportunity to gain practical knowledge of power station operations.

5. 2.SUMMARY
• This report details a summer internship at Gujrat State Electricity Corporation Limited (GSECL) in Gandhinagar,
Gujrat. we visited in four different section related to electrical field. Which are…….
• CPEM (Coal Plant Electrical Maintenance)
• Testing of electrical equipment’s
• Switchyard
• EMD (Electrical Maintenance Department)

6. 3. Description of the internship
• Gujarat State Electricity Corporation Limited (GSECL) is a wholly
owned subsidiary company of the Gujarat Electricity Board (GEB),
which came into existence in August 1993 after the unbundling of the
GEB. It is a power generation company working in the territory
of Gujarat, India. It delivers electricity through four distribution
companies – DGVCL, MGVCL, PGVCL and UGVCL.
I) About GSECL

7. II) INTERNSHIPACTIVITES
a) CPEM
• it is a coal handling plant in which coal is processed and stored automatically. hear by I mention certain function in
brief which can be well enough to get an overview.
a. Coal came through wagon trains
b. Wagon Tripler
c. Coal crusher
d. Conveyers
e. Bunker
f. Coal meal

8. Inside views of coal handling plant

9. b) Testing department
• In testing department we have learnt….
a. why protection is needed ?
b. How many protection are there
• Motor protection
• Transformer protection
• Generator protection

10. Motor protection
 Short Circuit Protection
 Thermal Over-Load Protection
 Earth Fault Protection
 Single Phasing/ Unbalanced/ Negative Phase
Sequence Protection
 Block Rotor Protection
 Differential Protection
Transformer protection
 Over Load Protection
 Earth Fault Protection
 Short Circuit Protection

 Line Backup Relay
Digital relay

12. c) SWITCHYARD
• In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used
to control, protect and isolate electrical equipment.
• Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type
of equipment is directly linked to the reliability of the electricity supply.

13. …CONTINUE
In GTPS two bus connection is used for the delivering of power to the grid. Both buses are connected with bus coupler.
There are five lines are feeding power to the grid. Which are listed below.
1) Chhatral
2) Soja
3) Ranasan
4) Jamla
5) Mehsana
