Abstract
Improving the performance of electric traction systems is associated with the use of new technologies, the introduction of which is preceded by an assessment of the technical efficiency of their work. Nowadays, electric energy storage systems in Russia have not found application in electric traction systems, but questions are being actively developed on advisability and possibility of their use. And electric traction load of electric traction system of the Moscow Central Ring is not an exception, which forms in the conditions of domination on the area of passenger traffic and frequent electric tractions stops. Electric energy of high level of return of electric trains was formed on the site. Obtaining the technical result of assessing the use of energy storage systems of electric energy is most expedient to perform on the basis of simulation modeling of the interaction of electric rolling stock and electric traction system in the conditions of the Moscow Central Ring. Modeling results allow receiving the main characteristics of storage units and voltage load graph, determining the duration of work episodes in charge and discharge modes, their number and appropriate total volumes of electric energy per day. The received results allow assessing requirements to the technical characteristics of storage systems in relation to work conditions in the electric traction system of the Moscow Central Ring and performing assessment of economic efficiency of this activity.
Highlights
Moscow Central Ring (MCR) is a railway area on which high technologies found application, which are used in Russia in the field of trains traffic organization, safety, traction and infrastructures [1, 2]
By the criterion of energy efficiency the best variant is the variant, which corresponds to inverter placement on traction substation of st
We can make the following conclusions: 1) energy volumes, which are realized by electric energy storage units on posts of sectionalization of MCR for charge and discharge modes, by work episodes, don’t exceed kWh
Summary
Moscow Central Ring (MCR) is a railway area on which high technologies found application, which are used in Russia in the field of trains traffic organization, safety, traction and infrastructures [1, 2]. In the electric traction system of MCR on traction substations, modern samples of power and switching equipment found application: dry converting transformers, fast acting switches, distributive devices of modular execution, modern rectifier converters etc. The electric traction system includes five traction substations and four posts of sectionalization. On the MCR area, passenger trains of the ES2G «Lastochka». The features of MCR should include the electric. © The Authors, published by EDP Sciences.
