CHOICE OF THE ELECTRIC TRACTION SYSTEM IN THE LIGHT OF RECENT SOLUTIONS

LA SCELTA DEL SISTEMA DI TRAZIONE ELETRICA AL LUME DI RECENTI SOLUZIONI

The advent of power electronics now makes it possible to modify, on board the locomotives, any characteristic of power taken from the contact line. Already for many years, contact lines in single-phase alternating current have fed almost exclusively locomotives with direct current motors. An era is now opening in which locomotives with three-phase motors will be fed from single-phase contact lines, but also direct current. The possibility of realizing systems "cross-bred" in any way makes it possible now to pursue optimization separately, in relation to the characteristics of the network studied, the individual components of the system: sub-stations and contact lines, on-board regulation, motors. The article examines the problem in the light of the latest solutions reached, in the phase of realization or, in any case, possible.
