The paper deals with research activities about technical aspects of dual source railway vehicles on the Czech railway traffic system. The thought vehicle uses for powered traction equipment the catenary and traction battery system. The battery system design is based on the traction and vehicular simulations.
-The paper describes the control of traction drive and control systems properties of a special rail vehicle WŽB10.1-M used in the Prague metro (subway). Measured values of main quantities of the control system and experience from duty are included. Software for the traction drive control system was developed at the University of Pardubice.
The paper presents the results of the experiments aiming at the quantitative assessment of the adverse effects that arise when the electric drive is powered by the alternating current (AC) power via a long cable. For elimination of negative influences were used various types of output EMI (electromagnetic interferences) devices. It was studied, how much mention devices reduce interfering influencesmainly overvoltage peaks and rate of voltage rise.
