    Simulation of the operation of the on-board energy storage in the tractional system of a quarry locomotive
    (State University of Infrastructure and Technologies, 2024) Kondratieva, Liliia; Overianova, Liliia; Tkachenko, Viktor; Riabov, Ievgen; Demydov, Oleksandr
    The ways of updating the rolling stock of open-pit railways have been considered and the main methods of using the energy storage on the locomotive for open-pit railways have been determined. A mathematical model has been developed, which includes a model of train movement along the railway section and during maneuvering and a model of energy processes in the traction system with onboard energy storage. Simulations were performed in a cycle that included movement from the crushing plant to the transshipment point with empty dump trucks, maneuvering during loading, movement from the crushing plant to the transshipment point with loaded dump trucks, and maneuvering during unloading. The simulation took into account the limitation of power consumption at the level of 4000 kW. The parameters of the energy storage device were determined, for which Toshiba SCiB 20Ah-HP cells were selected. The power of the energy storage is 3600 kW, and the energy capacity is 414 kWh. The use of modules for the formation of an energy storage device is proposed. It was determined that the energy consumption per work cycle with the selected energy exchange algorithm taking into account electrodynamic braking is about 200 kWh, and the charge reduction per drive cycle is 36%. The service life of the energy storage with the selected cells is estimated at 8 years.

    Research and Optimization of Hybrid On-Board Energy Storage System of an Electric Locomotive for Quarry Rail Transport
    (2023) Goolak, Sergey; Kondratieva, Liliia; Riabov, Ievgen; Lukoševicius, Vaidas; Keršys, Arturas; Makaras, Rolandas
    Operation modes of rolling stock at mining enterprises are considered and analyzed. The justification of the need to replace it with a modern specialized electric locomotive for quarry railway transport, equipped with an asynchronous traction electric drive and an on-board energy storage system, is presented. The determination of the parameters and structure of the on-board energy storage system, based on the condition of power compensation with limited power consumption from the traction network and ensuring the autonomous movement of the electric locomotive, is considered. This study was carried out by modeling the processes of energy exchange in the traction system of an electric locomotive. The use of lithium cells and supercapacitors in energy storage is considered. Variants of the hybridization of energy storage were studied from the standpoint of minimizing the weight, size, and cost indicators. It was established that reducing the mass of the energy storage device, which includes lithium cells and supercapacitors, leads to an increase in the cost of one kilowatt-hour of energy storage capacity, which reduces the attractiveness of capital expenditures for the creation of such an energy storage device. Hybridization of the energy storage device by combining lithium cells of different types practically does not improve its weight, size, and cost indicators. The recommended option is a storage capacity of energy based on LTO elements, for which it is necessary to select elements in order to minimize weight, size, and cost indicators.

    Assessment of the On-Board Energy Storage Parameters of the Locomotive for Rail Quarry Transport
    (Springer Nature Switzerland AG, 2022) Riabov, Ievgen; Kondratieva, Liliia; Overianova, Liliia; Goolak, Sergiy
    The use of on-board energy storage on a locomotive for rail quarry transport is considered. Three scenarios of energy consumption in the power supply of traction electric drive and auxiliary locomotive systems using on-board energy storage system (OESS) are considered. For each of the scenarios, simplified mathematical models of processes have been developed, which describe the energy exchange in the traction and auxiliary systems during exploitation of OESS. The input data for the calculations are the dependence of the power at wheel of locomotive on time, which is determined by the results of solving the traction task for the section railway line. Calculations has been made for the studied scenarios of OESS operation using data of locomotive operation at PJSC “Poltava Ferrexpo Mining”. It is defined that the parameters of OESS depend on the energy consumption scenario. It is proposed to use OESS on the locomotive with electric traction drive based on induction motors for PJSC “Poltava Ferrexpo Mining” according to energy consumption scenarios, which provide power from OESS during shunting and power from OESS when shunting with co-powered from the catenary for guide lifts.
