Abstract

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version). The studies were carried out with the support of the Russian Foundation for Basic Research for Project No. 17-20-01148 ofi_m_ RZD/17. ABSTRACT Based on the data regarding operation of locomotives of the series 2ES6 and 2ES10, the averaged parameters of the electric power storage in the DC traction system on lines with heavy and long-distance trains have been identified. The modes of the storage devices are characterized by a shortterm nature. The average duration of their operation in the charging mode is approximately 100 s, and the volume of the returned energy by the electric rolling stock, which determines the energy capacity, averages 100 kW•h, with a maximum power of 7,1 MW. The processing of measurement results shows that the observed distributions of stresses and traction load of the substation are not subject to Gauss’s laws.
