3. INRODUCTION
An electrical substation is a part of an electricity generation,
transmission and distribution system where voltage is transformed
from high to low or in reverse using transformers.

4. SUBSTATION DESIGN CRITERIA
• Sub-station should be located at load center
• Sufficient land area
• Grounding
• Easy of maintenance
• Possibility to Expand
• Reliability and Security
• Electrical design considerations

5. SUBSTATION PARTS
 SWITCH YARD
 POWER TRANSFORMATION
 FEEDER
 CONTROL ROOM
 PLCC
 EARTHING
SUBSTATION AUXILIARY
AC/DC SUPPLY
OIL HANDLING SYSTEM
ILLUMINATION
COMPRESSED AIR SYSTEM
SERVICE BAY
FIRE EXTINGUISHERS
SUBSTATION FUNDAMENTALS

6. SUBSTATION LAY OUT

7. SWITCHYARD EQUIPMENTS

8. MAIN FUNCTION OF SWITCHYARD.
 Switchyard protect the plant due to sudden damage outside the plant

9. POWER TRANSFORMATION

10. Power Transformers:
 These are used in substation to step up or step down the
voltage.

11. PROTECTION EQUIPMENTS

12. PROTECTION EQUIPMENTS:
Controls & protectc from abnormality in electrical system

13. PROTECTION EQUIPMENTS

14. CONTROLROOM & PLCC
Controlroom monitors the elecrical activities in a substation

15. FUTURE POSSIBILITIES

16. GAS INSULATED SUBSTATION:
GIS is the most suitable solution for indoor and underground
substations. In outdoor and hybrid substations, the occupied area is
tremendously reduced
by using GIS technology.

17. HTS (High Temperature Superconductors) substation
Many applications of superconducting technology such as HTS cable,
HTS transformer, HTS Fault Current Limiter (FCL), Superconducting
Magnetic Energy Storage(SMES) are analyzed .

18. INTELLIGENT ELECTRONIC DEVICES (IEDS)
Recent multifunctional Intelligent Electronic Devices (IEDs) provide
higher performance, reduction in operating cost, reduction in size, increase in
efficiency and improvement in robustness in the existing substations

19. DRY TYPE & SOLID STATE POWERTRANSFORMER

20. INTEGRATING &DISCONNECTING CKT
BREAKER

21. SELF MONITORED INSTRUMENT TRANSFORMER

22. WIRELESS COMMUNICATION
• Wireless communication is another option for data transfer from
substation switchyard to control house which does not require wire
installation in the switchyard.
• This solution is easy to install and provides compact low cost
solution.

23. The most significant features of fiberglass material are: cost-
effective, strong and durable, easy to install, corrosion and rot
resistant, safe and long lifetime.
 Fiberglass materials are a competitive alternative for steel,
wood and concrete in construction applications
FIBERGLASS APPLICATIONS IN SUBSTATION

24. CONCLUSION
The following are goals concluded for this approach:
 Adding new equipments to supplement existing
substation as well as paving the
 way for the future replacement of legacy solution
 Replacing existing equipment due to
performance or age deterioration as well as
 making it compatible for total future replacement
 Balancing the need for open system design and
cyber security demands while
 expanding the best practices and gradually
training personnel for new equipment
