Increased controllability of the distributed traction system in emergency mode

Abstract

The puprose of the work is to improve approaches to the controllability of power consumption in distributed power systems of electric rolling stock using modern technologies and equipment. Unequal energy consumption on the shoulders of the power supply causes additional losses in the system and makes the voltage mode worse on the current collectors of electric locomotives. To increase the controllability of operation modes, is proposed to use feeder volt-additional converters with arcless commutation of short-circuit currents. Using such converters allow to stabilize the voltage on the current collectors of electric locomotives and reduce the switching-off time. Variant calculations using the proposed circuit engineering of traction substations on the simulation model prove that the power losses from the equalizing currents are significantly reduced
