Dual Active Bridge converters for MV distribution lines into 1500 V DC metro railway system

Questo lavoro ha lo scopo di studiare l’integrazione di un convertitore Dual Active Bridge (DAB) sviluppato per linee di distribuzione MT in un sistema di trazione di una metropolitana ferroviaria urbana.

This work aims to investigate about integration of a Dual Active Bridge converter (DAB) developed for MV distribution lines into a traction system of an urban metro railway. Equipment is fed by 1500 V DC catenary and supplies active/passive loads at low voltage (750 V DC), providing galvanic insulation for safety reasons. Operation at very maximum voltage limits (up to 2 kV DC) and in case of MV drops and fluctuations have been simulated, focusing on system stability, control and proper sizing of passive filters to interface the converter with a storage device.
