    Analysis of the Electric Energy Consumption Components for Mine Train Traction
    (Dnipro National University of Railway Transport named after Academician V. Lazaryan, 2019) Arpul, Serhii V.; Artemchuk, Viktor V.; Babyak, Mykola O.; Vasilyev, Viacheslav E.; Hetman, Hennadii K.; Marikutsa, Serhii L.
    EN: Abstract. The paper considers the issues of reducing the energy intensity of transportation at opencast mining enterprises, the relevance of which has now increased due to the rise in the cost of fuel and energy resources. It presents the study results concerning the cost structure of the electricity consumed by electric mine transport, which form the basis for the development of technical and operational measures to reduce the energy intensity of the transportation process. It is shown that the work to reduce the electricity consumption for mined rock transportation should be aimed at: - Reduction of losses in the power circuits of the traction rolling stock due to the use of more advanced electric rolling stock and regulation of the degree of utilization of the installed traction power; - Introduction of new contact materials for electrical circuits with the lowest possible resistivity, including for current collector plates; - Introduction of measures to reduce energy consumption for power supply of auxiliary circuits; - Development and implementation of rational train control techniques. The introduction of energy-saving measures should include the development and application of effective methods for calculating individual norms of energy consumption and incentives for energy saving of the employees involved in the organization of the transportation process.

    Improving the System of Electricity Consumption Rationing
    (MATEC Web of Conferences, 2024) Arpul, Serhii V.; Afanasov, Andrii M.; Babyak, Mykola O.; Vasilyev, Viacheslav E.
    ENG: The main tool for reducing energy consumption in train traction is the construction of such a system of electricity consumption rationing, which will allow to reliably analyse and forecast energy consumption. This requires the development of a scientifically based system for rationing electricity consumption in train traction and its widespread implementation in locomotive depots. The purpose of the study is to improve the system of technical rationing of electricity consumption by freight trains. To this end, an attempt was made to solve the following tasks: to determine tools for assessing the impact of operational factors on electricity consumption using information from samples of drivers' route sheets by the method of statistical analysis; based on the conducted research, to propose an improved system of technical rationing of energy consumption in freight train traction. The proposed method of technical rationing allows for more accurate calculation of electricity consumption per trip and, as a result, provides a greater incentive effect for saving electricity by locomotive crews.
