The main objective of this paper is to present lithium iron phosphate battery modeling and experimental evaluation. The modeling of the battery was performed using the Thevenin equivalent circuit model with two RC branches and the nonlinear least squares method with the Levenberg-Marquardt optimization algorithm for parameter estimation. The modeling technique presents the most applicable and trivial solution to study and describe the behavior and performance of the battery. The experimental evaluation was performed on a 7,7 kWh battery pack installed at the Institute of Energy Technology, Faculty of Energy Technology, University of Maribor. Based on the estimated parameters of the Thevenin equivalent circuit, the model results show good agreement with measurements. The average mean absolute error method was used for determining the accuracy of the estimated parameters, with the state of charge and voltage being 8,38 % and 0,34 %, respectively.

The article is devoted to the results of studies of a simulation model of the hybrid diesel locomotive power plant electric drive, which consists of a free-piston internal combustion engine with a linear generator of electromagnetic type, energy storage and an electronic commutator. The functional diagram of a free-piston internal combustion engine with a linear generator of electromagnetic type works in two strokes (compression and piston) was built. The simulation model was made based on a functional diagram, a free-piston internal combustion engine with a linear generator of an electromagnetic type block diagram. The model has been tested on the Kharkiv - Borki road sections of 44.5 km with an average speed of 40 km/h and a train's weight of 600 tons. The analysis of the results of the simulation showed that the fuel consumption was 44.8 kg, which is 9% less than in traditional systems. Results of modelling show that the system with a free-piston internal combustion engine with a linear generator of electromagnetic type is a promising direction for the development of mechanical engineering.

The paper proposes a mathematical model of a three-phase induction motor with an asymmetrical twelve-zone winding of stator with parallel connection of subwindings. The mathematical model was developed using the theory of generalized electromechanical converter and contains equations of electrical equilibrium of six stator windings and three rotor windings. The equations for calculating the electromagnetic moment and the equations of motion of the induction motor with an asymmetrical twelve-zone stator winding rotor were obtained. The developed mathematical model in the form of cell-matrix equations has been implemented in MATLAB/Simulink.

The article examines the composition, structure, mechanisms of acquisition and opportunities for developing student professional competencies based on the integration of electrical engineering disciplines. The possibilities of implementing a structural and content model of professional competence development are analysed. In our opinion, the competences should be developed on the basis of integrative, competence and informational approaches. It has been proved that the professional competencies of electrical engineering students could be developed more effectively while using design and construction activities implemented in the educational process on the basis of the unity of theoretical knowledge and individual work of a student. Comprehensive research made it possible to conclude that it is necessary to involve students not only in various types of research activities but also in the development of educational and methodological complexes of integrated disciplines. This will contribute to the development of integrative professional basic knowledge and, in turn, to the professional competences of students.

The paper is devoted to the search for effective approaches to the educational process organization of electrical engineering students in emergency situations, in conditions of epidemiological, ecological, and man-made threats, during martial law. The world experience of organizing training under martial law is analyzed. The existing models of using blended learning educational technology are considered. A new model of the educational process, which is well adapted and most fully meets the requirements of extreme conditions is suggested. The efficiency of the new comprehensive approach to the organization of blended learning was tested by the authors in the 2021/2022 academic year at Kremenchuk Mykhailo Ostrohradskyi National University. The results of experience in implementing the blended learning laboratory workshop on the base of the Digital Competence Office equipped with DIgSILENT PowerFactory software for undergraduate and graduate students of the specialty 141 “Electric power engineering, electrical engineering and electromechanics” are presented.

Efficiency of power consumption requires studying a number of problematic issues, the solution of which allows us to formulate and summarize regularities of this process. Analysis and synthesis of optimal indicators is the basis for a more in-depth interpretation of new facts obtained at the empirical level. This makes it possible to evaluate the process of electrical power consumption at energy-intensive enterprises, including mining ones in particular. The current level of electrification of mining production enables specifying a number of properties of this process in some general terms. Relevance of their study is due to an increase in power consumption efficiency at mining enterprises. These properties should undoubtedly be attributed primarily to efficiency of power supply and consumption. Simultaneously, an important aspect in conducting the research is the fact that increased efficiency of power consumption at mining enterprises is inextricably linked with the problem of evaluating changes in power consumption modes over time, which is essential and is determined by specifics of mining conditions. The research aims to develop a synergistic mathematical model for optimizing power consumption through total cost indices of power consumption by iron ore mines' consumers. On the basis of methodological foundations of synergetics and methodological approaches to nonlinear optimization, the authors' synergistic mathematical model is formed. By combining characteristics regarding power consumption at time intervals in options that represent power production by an enterprise itself and by external sources it is possible to develop a synergistic optimization model and offer a relevant solution method.

The paper proposes a technique for calculating the force characteristics of a radial active magnetic bearing with an eight-pole stator with a given control law. This approach is based on the application of the finite element method and a software package for a general technical analysis of physical processes. Variable data of the technique are: the bearing design parameters, the control law parameters and the initial data of a variant parametric analysis of magnetic forces depending on the position of the rotor in active magnetic bearings and control signals. Geometric and finite element calculation models are three-dimensional. They accurately reconstitute the geometry of the stator and rotor parts of magnetic circuits, pole coils, internal and external air spaces and air gaps between the rotor and the pole. The active magnetic bearing control law is control voltages on electromagnets windings. Their values depend on the instantaneous position of the bearing journal and the instantaneous values of currents in pole coils circuits. In finite element calculation models, the load is specified in the form of current density in the volumes of the coils, taking into account the direction of the turns at each point. Its value is determined in accordance with the control law and the parameters of electrical circuits. The magnetic forces are calculated from the Maxwell tension tensor in a given cloud of points of the rotor position. The force characteristics are dependences of the restoring magnetic forces on the displacement of the bearing journal in two radial directions. The results of computational studies to determine the dependences of magnetic forces on rotor displacements for the design of an active magnetic bearing used in an experimental scale model of a turbocompressor of a gas compressor unit with active magnetic bearings are presented. Validation of the approach and results was performed by comparing the calculated and experimental data.
