Abstract
The paper discusses the traction parameters of an electric locomotive of a new generation. The existing schemes of sections served by electric locomotives and locomotive crews at the studied railway operating domain are presented. A comparison of the main parameters of DC and single-phase AC electric locomotives, the operation of which is currently organized at sections with trains of estimated weight in the long-term traction mode on the ground slopes with different steepness, is made. The scheme of the proposed organization of operation of dual-voltage electric locomotive and locomotive crews is presented. Traction parameters of a dual-mode electric locomotive are calculated, taking into account the plan and profile of the track at the proposed sections of operation, the specific basic resistance to the movement of the locomotive and the train at the estimated speed, the specific accelerating and decelerating forces of the train. When dual-mode electric locomotives are put into operation, it will be possible to reduce the fleet of locomotives in operation, the number of locomotive runs due to their lengthening, and the number of locomotive crew relief points, reduce the transit time of freight trains, increase technical and service speed, average daily mileage and average daily performance of the locomotive, reduce power consumption for traction. The operation of such electric locomotives contributes to the development of technologies for rail traffic management and the improvement of quantitative and qualitative indicators of various railway facilities.
Highlights
Improving the efficiency of the transportation process by railway transport depends on the integrated development of infrastructure
According to the results of the calculations, we conclude that the 2EV120 “Prince Vladimir” electric locomotive can perform train operation at the Artyshta II - Altayskaya locomotive run in accordance with the train weight standard previously established by the order of the Deputy General Director of the JSC “RZD” Head of the Directorate of Traction Z-SIB TsT-108 dated May 30, 2017 “On the establishment of standards for the weights and lengths of passenger and freight trains at the sections served by the West Siberian Directorate of Traction” [15]
On the basis of the calculations made, it is possible to assess the technological effects of the introduction into operation of the dual-mode freight electric locomotive 2EV120 at the Mezhdurechensk - Vkhodnaya operating domain in comparison with the currently operated locomotives
Summary
Improving the efficiency of the transportation process by railway transport depends on the integrated development of infrastructure. The most important indicators of electric locomotives in operation are the maximum weight of trains that they can drive at different sections, the speed on which the travel time depends, and the specific energy consumption for traction.
