Introduction
The graduation Project of our group is proposed from TRANSCO to UAE University.
Transco Company is building now new Grid Substation in RAMAH to provide the enough power to that area.
Substation is the place where the power is stepped up or down.
Substation contains:
Feeder
Transformer
Busbar
Bus coupler.
Other Protection equipment
Ramah Grid Substation power is stepped down by transformers from 220 KV to 33 KV.
Transformer Protection
Over Current Protection
In the event of failure or non- availability of the primary protection some other means of ensuring that the fault is isolated must be provided. These secondary systems are referred to as ‘back-up protection.
Back-up protection
Conclusion
In this GP; there were long steps of calculations and simulation using PSCAD program which allows the designer to simulate the large values of power in details.
After doing all these steps; the simulated results will be sent to Transco Company to be as a real setting for the protection system..
