Abstract

The actuality of questions of energy saving in the traction power supply doesn’t give rise to doubts. At the same time in such complex composition as the traction power supply system, taking into account its cooperation with the electric rolling stock, questions solving of the energy efficiency increase must be accompanied by a complex efficiency assessment of the proposed activities. The technical and organizational arrangements implementing with this purpose in mind must not just secure the decline of the power intensity level of the vehicular process, but allow securing this vehicular process in the requisite volumes with excellent prospects at the moment and also be economically expedient. At present no such technologies and especially software tools exist which allow estimating and predicting the alteration of the energy efficiency indices of trains’ traction regarding the current values by change of the engineering parameters of the traction power supply system and the operating data of the railways’ areas. In this article a creation necessity of an intelligent monitoring system and an indices programming of the traction power supply system is justified, allowing determining the influence grade on the basic energy efficiency indices of the operational factors and the characteristics of the traction power supply system and to determine the optimal combination of these factors and characteristic for the justified changes planning of the traction power supply system characteristics and the improvement of the operational indices of trains’ traction in the view of the achievement of the maximal energy efficiency. The architecture of such a system is described. The tasks which solution allows practically realizing and implementing in maintenance the proposed elaborating are formed.

Highlights

Of 85.5 thousand km of general operational length of the railways in JSC «Russian Railways» the electrified lines amount 43.6 thousand km
The maintenance costs in JSC «Russian Railways» are about 10 % of total company consumption; it is around 170 billion rubles per year
As the systems like analytical system using ob the Moscow central ring are extremely expensive and don’t have a widespread occurrence on the railways’ network, the suggesting development orienting at the work with the active accounting of JSC «Russian Railways» is actual and competitive

Summary

Introduction

Of 85.5 thousand km of general operational length of the railways in JSC «Russian Railways» the electrified lines amount 43.6 thousand km. It is the second index in the world after China. The maintenance costs in JSC «Russian Railways» are about 10 % of total company consumption; it is around 170 billion rubles per year. That is why almost any actual working energy-saving production, which is realized in the company scales, can bring saving measuring by billions of rubles and that is why it can be actual and significant. According to the Long-term development program of JSC «Russian Railways» in the field of foreground technologies which possess the highest integrated assessment of potential influence on the level of holding-company competitiveness, there are such technologies as:
