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.
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.
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, Sergey
The 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.
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, Liliia
The 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.
Procedure for modeling dynamic processes of the electromechanical shock absorber in a subway car
(Технологический центр, 2019) Liubarskyi, Borys; Lukashova, Natalia; Petrenko, Oleksandr; Yeritsyan, Bagish; Kovalchuk, Yuliia; Overianova, Liliia
A procedure has been devised for modeling the dynamic pro-cesses in the proposed structure of an electromechanical shock absorber. Such shock absorbers can recuperate a part of the energy of oscillations into electrical energy allowing the subsequent possibility to use it by rolling stock. The procedure is based on solving the Lagrange equation for the electromechanical system. The model’s features are as follows. The model takes the form of a Cauchy problem, thereby making it possible to use it when simulating the processes of shock absorber operation. Two generalized coordinates have been selected (the charge and displacement of the armature). The components of the Lagrange equation have been identified. Based on the results from magnetic field calculation and subsequent regression analysis, we have derived polynomial dependences of flux linkage derivatives for the current and linear displacement of an armature, which make it possible to identify a generalized mathematical model of the electromechanical shock absorber. The magnetic field calculations, performed by using a finite-element method, have allowed us to derive a digital model of the magnetic field of an electromechanical shock absorber. To obtain its continuous model, a regression analysis of discrete field models has been conducted. When choosing a structure for the approximating model, a possibility to analytically differentiate partial derivatives for all coordinates has been retained. Based on the results from modeling free oscillations, it was established that the maximum module value of current is 0.234 A, voltage – 52.9 V. The process of full damping of oscillations takes about 3 seconds over 4 cycles. Compared to the basic design, the amplitude of armature oscillations and its velocity dropped from 13 to 85 % over the first three cycles, indicating a greater efficiency of electromechanical shock absorber operation in comparison with a hydraulic one. The recuperated energy amounted to 3.3 J, and the scattered energy – 11.5 J.
