A planning study on power systems of metro-transit transportation system

A simulation program, implementing a deterministic-probabilistic methodology, has been applied to an Italian railway line (Roma - Ostia Lido), whose operation is going to be changed from railway to metropolitan service. The application tasks are to point out possible critical issues of the present supplying power systems and to provide proposal about their future optimal upgrading. In order to get the real values of the main electrical parameters of electrical sub-stations (ESS) of the railway line for the simulation, an experimental survey has been performed. The paper reports the main experimental and simulation results.
