Mathematical and computer models of systems with magnetoelectric converters have been improved, which allow to refine and minimize energy losses in mechatronic systems. Improved methods and mathematical models, which became the basis for creating software for forecasting the amount of electricity produced by power plants with renewable energy sources (RES), which allows to increase the accuracy of forecasting. For the first time, a method for multiphysical modeling of long-term and time-varying electromagnetic and thermal transients in induction channel installations has been developed. The modeling of interconnected physical processes in an electron beam skull furnace with controlled electromagnetic stirring of liquid metal is carried out. A new technological regulation of metal smelting in such a furnace has been developed. A new electromagnetic system for mixing liquid metal with orthogonal magnetic fields, which is recommended for use in crucible melting furnaces and in continuous casting machines, is proposed and investigated. Based on the results of studies of normal and emergency modes of electric networks with renewable energy sources, a structure of emergency automation has been proposed for a typical energy center of the UES of Ukraine. Recommendations on the prevention of the appearance and development of ferroresonance modes in the distribution electric networks of Ukraine taking into account renewable energy sources have been developed. A working electricity meter has been manufactured to account for its active and reactive components in an extended range of changes in phase angle between current and voltage vectors. A semiconductor converter for powering a controlled electromagnetic mixer of an electron beam furnace has been developed. Working design documentation for high-potential power supply units of electron-beam melting plants has been developed. A numerical and experimental study of the characteristics of an electric machine with permanent magnets has been carried out. An experimental model of a starter-generator was developed and its experimental studies were carried out. The models of vibrational diagnostic signals are improved and investigated, the parameters of these signals characterizing the technical condition of the working electrical equipment are determined. The main diagnostic features that provide the ability to identify typical defects of its nodes are substantiated. The structure, manufacturing and practical testing of individual modules of the prototype of a multi-level diagnostic system for electrical equipment of thermal power plants were carried out. A prototype of a unified basic module of the measuring channel for the implementation of information-measuring systems has been created.
