Description of the project:

Model of the DC traction network plus the AC medium voltage grid. The model of the inverter has been developed specifically for this project. The following problems are solved with the simulation tool: - Is the voltage of the contact wire and 3rd rail within the values defined in EN50163? - How many inverters and where should be placed for a sustainable investment? - Are low voltages on the system producing delays on the timetable? - How many new substations are needed to run the new frequency? - Which is the effect of the DC traction network in the AC medium voltage network? - Are needed extra feeding cables to deliver all the energy required for the new schedule? - Which is the maximum capacity of the metro system? Find the highest frequency with no extra investment. - How many ebus chargers can be fed directly from the medium voltage network of the metro system without affecting the metro operation? - Which is the maximum temperature of the contact wire?
