Abstract
The paper considers the application of the “Digital Railway” project at the traction substation. The “Digital Railway” project should become a centralized system uniting the programs for the control of railway elements. In the traction power supply system, the application of digital technologies is often understood as the application of data transfer protocols of the International Energy Commission “IEC 61850”. The substations that switched to this information protocol are usually called “digital”. An attempt to introduce the “digital substation” technology only by completing a set of corresponding equipment can give a negative result of its application. The efficiency achieved through the technical upgrading of equipment (reduction of losses for own needs, reduction of electromagnetic influence, reduction of analog signal input channels, reduction in the number of cable products used, and improvement of the measurement accuracy class) may not be sufficient to pay for the project. The qualitative integration of all involved services in a single information process of monitoring and controlling the digital substation will increase the efficiency of its application. As a positive experience when considering the use of digital technologies in traction power supply systems, one can cite the Automated system for monitoring the railway transport infrastructure developed and implemented by the staff of the Far Eastern State Transport University at a number of traction substations of the Far Eastern operating domain and at the 2ES5K “Ermak” electric locomotive. In addition, this system already has a support of IEC 61850 protocols.
Highlights
No 86 “The definition of directions of scientific research in the field of digitalization and the formation of recommendations for the implementation of the concept of “Digital Railway”, the “Digital Railway” project should become a centralized system uniting the programs for the control of railway elements” [1]
The Digital Railway” (DR) can be defined as a new concept for the organization and control of the railway transport system based on a digital support system that uses digital systems to increase efficiency and reduce the negative aspects of the railway transport system [2]
It should be noted that a number of manufacturers motivated to improve their products and implement best practices in the use of information systems already today support the IEC 61850 protocols in the manufactured devices, which are installed in traction substations
Summary
According to the Minutes of the meeting of the Joint Scientific Council of Open Joint Stock Company “Russian Railways” of October 26, 2017 No 86 “The definition of directions of scientific research in the field of digitalization and the formation of recommendations for the implementation of the concept of “Digital Railway”, the “Digital Railway” project should become a centralized system uniting the programs for the control of railway elements” [1]. Https://doi.org/10.10 51/matecconf /201823901051 systems[2] This innovative approach on railway transport will facilitate the integration of various railway subsystems and the integration of the railway system with other modes of transport in terms of the development of a mobility service base. The very concept of the “Digital Railway” (DR) exists in several countries for the last several decades [3] During this time, digital technology, information systems and related technologies have undergone significant development and renewal and even a change in the technological order. Introduction of the DR project assumes a return in the form of an increase in the amount of transported goods, while simultaneously increasing energy efficiency and lowering the cost price This should be achieved by improving the efficiency of the railway and improving the safety of service personnel. The innovative approach is to link railway vehicles with related infrastructure [4,5]
