    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.

    Improvement of the model of power losses in the pulsed current traction motor in an electric locomotive
    (ПП "Технологічний Центр", 2020) Goolak, S. O.; Sapronova, S. Yu.; Tkachenko, V. P.; Riabov, Ie. S.; Batrak, Ye. O.
    When studying transients in pulsed current traction motors, it is important to take into consideration the eddy and hysteresis losses in engine steel. Magnetic losses are a function of the magnetization reversal frequency, which, in turn, is a function of the engine shaft rotation frequency. In other words, magnetic losses are a function of time. Existing calculation procedures do not make it possible to derive the instantaneous values of magnetic losses as they are based on determining average losses over a period. This paper proposes an improved model of magnetic losses in the steel of a pulsed current traction motor as a function of time, based on the equations of specific losses. The adequacy criteria of the procedure for determining magnetic losses in electrical steel have been substantiated: the possibility to derive instantaneous values of magnetic losses in the magnetic material as a function of time; the possibility of its application for any magnetic material; and the simplicity of implementation. The procedure for determining magnetic losses in the steel of a pulsed current traction motor has been adapted by taking into consideration the magnetic properties of steel and the geometry of the engine’s magnetic circuit. In order to determine the coercive force, the coefficient of accounting for the losses due to eddy currents, as well as the coefficient that considers the losses on hysteresis, the specifications’ characteristics of specific losses in steel have been approximated using the pulsed current traction motor as an example. The simulated model of magnetic losses by the pulsed current traction motor has demonstrated the procedure for determining average magnetic losses and time diagrams of magnetic losses. The proposed model for determining magnetic losses could be used for any magnetic material and any engine geometry under the condition of known material properties and the characteristics of change in the magnetic flux density in geometry.
