Electromagnetic compatibility between 25 kV-50 Hz rail system and parallel 3 kV d.c. lines: influence on d.c. electronic traction converters

摘要

This paper reports on the investigation performed by field tests and simulation about the behaviour of an electronic rail vehicle supplied by a d.c. voltage with a 50 Hz ripple induced by a parallel high-speed line. Measurements recorded in the Italian Railways (FS ― Trenitalia) 25 kV-50 Hz test site are used to elaborate the input data and to choose significant conditions for the simulations. Simulation results, as well as measurement results are presented.
