Features of construction of modern systems for automatic power redundancy of traction substations DC

Abstract

The article presents the results of studies on improving the efficiency of electrical power redundancy systems in power supply systems of railway DC vehicles by improving the technological modes of traction substations. There are presented scientifically based technical solutions of the hardware, a control algorithm of the power reserve system for traction substations with two converter units and a methodology for selecting places for installing automatic power reserve systems to increase the efficiency of the power supply system for railway vehicles. Practical testing of the developed technical and technological solutions has shown the effectiveness of their use in operating conditions.
