Abstract

The article describes core criteria, which define efficient application of energy accumulators in railway traction power supply system. Installation points for energy accumulators in electric power system of train electric drivers, where application is most effective, are identified. These points are railway sub-stations, electric traction network and traction power system. The main types of energy accumulators, which essentially can be used on railway transport in traction power system – traction sub-stations and traction network, electric motive power, are examined. They can be used on railway transport and. The quality factors of work for traction energy power and electric motive power are presented, improvement of which can be performed using energy accumulators. International experience of energy accumulators application for railway transport is presented. Russian developments and implementation of energy accumulators from domestic manufacturers are examined, both in the traction power system and in the electric rolling stock. The polygons for the most efficient use of energy storage in the traction power supplying system are identified.

Railway transport is a consumer of country energy system’s products, but, at the same time, is a technological link in a chain of production, transporting and consumption of energy

Summary

Introduction

Railway transport is a consumer of country energy system’s products, but, at the same time, is a technological link in a chain of production, transporting and consumption of energy. Traction power supply system of railway transport is one of the most heavy consumers of electric power. At peak loads generated by start-up currents which are superimposed in the feeders, the voltage on bus bars of traction sub-station and in traction power system on intermediate stations that are located between the two closest traction sub-stations reduces. It feels especially strong in the end of console sectors. This slows down trains launching processes and leads to additional electric power losses in traction power supply system. For https://doi.org/10.10 51/matecconf /201823901057 these reasons traction sib-stations power equipment has extensive available capability, which is necessary for load factoring
