PROPOSALS FOR THE RECONSTRUCTION OF TRACTION SUBSTATIONS

Abstract

Currently, the problem of the need to reconstruct traction substations of electrified railways has become more acute. This is due to the fact that most of them on many railways have been in operation for more than half a century, and have suffered significant physical and moral damage. Continued operation of such equipment can lead to its failures, to disruption of power supply to consumers, to the development of emergency situations. The potential occurrence of such damages is confirmed by a statistical analysis of failures of traction substation equipment, the results of which are presented in this paper. An analysis of the service life of the equipment of one of the traction substations of the Eastern landfill was also performed, which confirms the presence of a significant percentage of equipment with a service life exceeding 35 years. An economic calculation was made to determine the operating costs, taking into account the existing equipment for the substation under examination. Their magnitude is significant.

In connection with the above facts, an urgent task is to make technical decisions on the reconstruction of traction substations. At the same time, it is proposed to use brands of modern equipment that is low-cost in operation and highly reliable, according to existing operating experience. The assessment of operating costs after reconstruction allowed us to conclude about the effectiveness of the proposed solutions, which can be extended to other traction substations.

The implementation of the recommended solutions for the replacement of equipment at traction substations will lead to lower operating costs, increase the reliability of not only traction substations, but also the entire traction power supply system, and increase the safety of the transportation process.
