Abstract :
A test plant at Ansaldo Trasporti (Naples) has been built up, with the aim to conduct the functional qualification tests of railway vehicles at full load. It comprises a variable DC voltage fully regenerative static power supply (rated 4200 VDC, 4000 A), four roller banks, equipped with regenerative DC motor drives (each one rated 1500 kW), and an automation system, based on two levels. This paper describes the characteristics of the power supply and of the automation system. The static power supply is composed by two 12 phase series connected thyristor power converters with a DC output filter limiting the DC harmonics content. Its control system is asked to modify the DC output voltage according to laws that simulate the railway DC line variations. The automation system has a level 1 composed by four PLCs controlling respectively the roller banks DC motor drives, the main power supply and the electrical distribution, and a level for tests management, data acquisition and operators guide
