Документ 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, OleksandrThe 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.Документ Research on the application of on-board energy storage on an electric locomotive for quarry railway transport(2023) Kondratieva, L. Yu.; Overianova, L. V.; Riabov, Ie. S.; Yeritsyan, B. Kh.; Goolak, S. O.Methods of using on-board energy storage system on rolling stock are considered. Their use ensures a reduction in energy consumption and reduces the impact on the environment. Concepts of managing energy flows in the traction system of an electric rolling stock equipped with onboard energy storage systems are considered. It is proposed to apply the concept of control on an electric locomotive for quarry railway transport, which consists in reducing the current consumption from the traction network during the acceleration of the rolling stock and compensating the power during movement with the lowest voltage on the current receiver. For the selected control concept, a simulation of the train movement on the test section was carried out while varying the value of the limit current consumed by the electric locomotive from the traction network. The power of the energy storage device and its working energy capacity is determined. Based on the results of the study, it is justified to limit the current consumed by the electric locomotive of the traction network at the level of 600 A.Документ Determination of the working energy capacity of the on-board energy storage system of an electric locomotive for quarry railway transport during working with a limitation of consumed power(Warsaw University of Technology, 2023) Kondratieva, Liliia; Bogdanovs, Arturs; Overianova, Liliia; Riabov, Ievgen; Goolak, SergeyThe use of specialized rail rolling stock which is used for transporting ore from the quarry to the crushing plant at mining enterprises is analyzed here. Electric locomotives with an asynchronous traction electric drive and an on-board energy storage system are considered for use. The calculated dependencies of the electric locomotive tractive power were analyzed and it was established that on flat sections of the track profile, the movement is carried out with a power that does not exceed 50% of the nominal one. The movement with the nominal power is carried out on the controlled uphill during the cargo half-passage. To ensure the necessary power for movement in such areas, the use of an on-board energy storage system is proposed, which should feed the traction system while limiting the power consumed from the catenary. This happens when the voltage on the pantograph drops to a minimum level. The aim of this work is to determine the on-board energy storage system parameters during the operation of the electric locomo-tive with limitation of the power consumed from the traction network. Mathematical models of the energy exchange processes in the electric locomotive traction system have been developed. The criteria for comparing options for cal-culating the parameters of the on-board energy storage system have been proposed. The criteria take into account the reduction of energy consumption during movement, the efficiency of energy storage, and the complete use of the on-board energy storage system in terms of power and working energy capacity. Based on the calculation results, it was determined that the use of an energy storage device with a power of 3,540 kW and an operating energy capacity of 63.5 kWh provides a 10% reduction in energy consumption, which is being consumed while moving along the sample section of the road. The current that can be consumed by an electric locomotive with such parameters of the on-board energy storage system is limited by 600 A.Документ Increasing the energy efficiency of the multi-motor traction electric drive of an electric locomotive for railway quarry transport(2023) Riabov, Ievgen; Goolak, Sergey; Kondratieva, Liliia; Overianova, LiliiaThe improvement of the energy efficiency of an electric locomotive for railway quarry transport with a multi-motor traction electric drive while disconnection of the traction electric motors has been investigated. Mathematical models of the movement of the train on the track section and during manoeuvring, as well as the model of the energy exchange processes in the traction electric drive, which are used to perform the traction task when the train moves on the track section, have been developed. Through mathematical modelling, the calculation of energy during movement on the track section was performed with all connected and partially disconnected electric motors. When part of the electric motors are disconnected, the energy consumption is reduced by 10% for the cargo half-passage, and by 27% for the empty direct passage. The reduction of energy consumption with disconnected electric motors during manoeuvring has been noticed. The obtained results confirm the expediency and necessity of conducting research aimed to increase the energy efficiency of the multi-motor traction electric drive of an electric locomotive for railway mining transport.Документ Покращення енергоефективності моторвагонного рухомого складу(Східноукраїнський національний університет імені Володимира Даля, 2023) Нещерет, Володимир Олексійович; Іванов, Костянтин Ігорович; Рябов, Євген Сергійович; Овер'янова, Лілія ВікторівнаДокумент Оцінка потенціалу енергозбереження при застосуванні рекуперації енергії на моторвагонному електрорухомого складу для приміських перевезень(Національний технічний університет "Харківський політехнічний інститут", 2023) Буряковський, Сергій Геннадійович; Овер'янова, Лілія Вікторівна; Нещерет, Володимир Олексійович; Іванов, Костянтин ІгоровичВирішено серію тягових задач для ділянки Харків-Пасажирський – Мерефа при русі базової секції електрорухомого складу. Встановлено, що коефіцієнт рекуперації для секції змінюється у діапазоні 0,26 – 0,47 і залежить від допустимої швидкості руху. Визначено, що потужність бортового накопичувача енергії має відповідати нормативній потужності тягового електроприводу, яка дорівнює 1200 кВт. Енергоємність накопичувача, який працює у режимі акумулювання енергії та живленні тягового електроприводу, становить 8,2 кВт·год.
