Main goal
Power system design of transformation and voltage traction stations for light
rail trains, focusing on continuous power supply while minimizing pollution
level to the national power grid
Demands
•
High AC power conversion 12.6kV at 50Hz frequency to 750VDC
•
Power required to a single segment of the train is 1000 kW [about 1.3kA]
•
Total power needed for each station
:
−
Depot Substation M103
:
6.8MVA
− Edge Substation M111
:
2.36MVA
•
Backup power supply from additional feedstock source
•
Uninterrupted power supply even during maintenance work
•
Compliance with extreme load conditions when a malfunction happens at a
nearby station
•
Planning under the Electricity Law and Regulations
