“…The investigated system is made with two frequency converters, which makes it possible to place the wind turbine and pump separately from each other to increase the efficiency of the system in selecting the optimal areas for objects [6]. It also allows to introduce an additional source of energy from other types of alternative sources, such as solar energy, which do not require additional control [7].…”

The nature of the efficiency change in pump systems powered by an alternative source of electricity in conditions of a given pressure stabilization is investigated. An electromechanical water supply system powered by an alternative energy source using a static compensator (STATCOM) is considered. The observer of energy efficiency of the pump installation based on theory of artificial neural networks, which training occurs on the basis of static characteristics of the unit, is constructed. The results and analysis of investigations of the efficiency level changes during a typical daily cycle of water consumption are shown. References 12, figure 5.

In a lithium-ion battery, the crossing of its charging–discharging curves represents an unambiguous current capacity. The reproduction of a complete charging–discharging cycle defines the maximum possible charge for a current battery state. When obtaining of the curves experimentally, one should consider the duration of polarization or depolarization. It is reported that the battery capacity depends considerably on the value of the battery’s internal resistance as this value defines the location of the actual charging–discharging curves relative to the nominal curves, i.e., the point of their crossing shifts. The present study aimed to develop a diagnostic algorithm for the batteries of electric vehicles for a complete charge–discharge cycle, considering the processes of polarization and depolarization. The mathematical expressions for determining the internal resistance and the complete charge of the battery were obtained. The novelty of the present study is in the fact that by applying extrapolation to a simple electrical model of a lithium-ion battery, the degree of degradation and the current charge could be predicted without the requirement of lengthy experimental procedures.

Purpose. Mathematical modeling of high-frequency periodic processes in winding power transformers to improve the technology of their design and operation. Methodology. The methods of the formation of mathematical models for the research of high-frequency periodic processes in transformers and methods of solving systems of partial differential equations are applied. Findings. The mathematical model for the research of high-frequency periodic processes in two-winding transformers, with adequate considering of electromagnetic connections of windings and structural parameters of transformers, is created. Originality. To form a mathematical model for the research of high-frequency periodic processes, a substitute scheme of a two-windings transformer, taking into account the parameters of the electric and magnetic circuits of windings and electromagnetic connections between them, is proposed. Practical value. The mathematical model, which allows analyzing the voltage distribution in the transformer windings for high-frequency periodic processes in windings, and adjusting their insulating abilities, is created.
