Methods of analysis and corresponding algorithms for the research of induction motors with short-circuited rotor taking into account saturation and displacement of currents in rotor rods are developed, which allowed to create mathematical models suitable for design and analysis of operation of electric drives with periodic load. An approach for modeling electrical devices using differential electromagnetic parameters based on a magnetic circuit with a single magnetic flux is proposed. An improved universal mathematical model for the analysis of low-frequency electromagnetic processes in a power transformer is proposed, taking into account the connection schemes of the windings and the parameters of its electrical circuits and the design of the magnetic circuit in MATLAB / Simulink Methods of protection of overhead transmission line wires from ice loads are considered. The expediency of using the winding method in creating passive protective coatings on the wires in operation conditions based on the use of LineScout technology is developed. Problems of mathematical modeling of biological objects using electrotechnical approaches are considered and mathematical and simulation models of nerve impulse conduction along a neuron axon are developed, which allowed to take into account geometric, physical and chemical parameters of neuron processes.
