The life cycle of an electrotechnical system begins with design. The individual characteristics of life cycle enterprises, the technologies used, the qualifications of engineers and workers, and many other factors affect the design results. The design efficiency of complex electrotechnical systems is ensured by the integrity of approaches and integration, understood in a broad sense. Various factors are integrated: design tools, stakeholders, employee qualifications, the internal organization of operational structures, etc. An approach based on the idea of describing an electrotechnical system as a sociophysical object of complex nature is described. The sociophysical approach allows a new use of well-known design tools. The project to create an electrotechnical system is considered as a dynamic process associated with overcoming a potential barrier in the sociophysical space

An analysis of domestic and foreign developments in the field of full electric aircraft showed that a reduction in full takeoff weight, operating costs, maintenance time and the increase of fuel efficiency is possible with the growth of electrification. Nowadays such aircraft are created only for a small number of passengers and the power of their electric motors is negligible. However, all the concepts of large full electric aircraft imply the use of high temperature superconductor technologies. The most promising concept for high temperature superconducting electric machines with high specific parameters technically feasible in the near future is a fully superconducting synchronous electric machine with a nonmagnetic core. At the output power of more than 1 MW, the specific power is anticipated to exceed 10 kW/kg at 77 K. The fundamentals of theory and the analytical technique for calculating the basic parameters of a fully high temperature superconducting electric machine with an outer ferromagnetic screen have been developed. To refine the developed analytical method, the 1,5 kW prototype of the all-superconducting electric motor for hybrid distributed propulsion system was developed. It was shown that the analytical calculation provides sufficient accuracy in determining specific power and other basic parameters of fully superconducting electrical machine.

This paper presents the results of testing high-torque brushless DC motor with a peak power output of 3.35 kW for gearless electromechanical steering actuator. Experimental studies of nominal parameters, static stability and heating of a high-torque brushless DC motor are presented. During the test, the values of torque, maximum static load and temperature of the stator winding were obtained. The curve output-torque from rotation-speed obtained during the tests has good convergence with the modeling in Ansys, and differs by no more than 10%. Heat tests showed the effectiveness of thermal parameters. The measurement of the active resistance of the stator windings, the measurement of the residual magnetization of the permanent magnets, carried out after the tests, confirm the performance of the prototype of a brushless DC motor.

This paper presents the way to reduce losses in distribution networks separating the issues of application of amorphous alloy in magnetic cores of power transformers used in trans-former substations 20/0,4 kV. The voltage transfer of electric networks from 6/10 kV to 20 kV allows to increase the capacity of distribution networks at least 2–2.5 times within the same territory space, to reduce the number of transformer substations, to increase the quality of electric energy and the reliability of power supply systems. The results of comparative calculations of electric energy losses for transformer substations 6, 10 and 20 kV are presented.

The load capacity of five legged power transformer during geomagnetic disturbances was investigated. As an object of the research was chosen the 242/20 kV, 400 MVA, five legged power transformer. The aim of investigation was to determinate the acceptable level of power transformer load capacity by the criterion of the above-limit value of windings temperature excess over ambient temperature. To obtain quantitative estimates of the temperature criterion, additional losses due to eddy currents arising under the influence of geomagnetically induced quasi-direct currents was preliminarily determined and additional main active power losses caused by an operating current increase due to a multiple increase in the magnetizing current. The values of the geomagnetically induced quasi-direct currents in quantitative estimates corresponds to the recorded results of those currents in electric power systems. It was shown that the greatest increase in additional power losses is observed in grounded high-voltage windings, and in low-voltage windings the additional losses increased insignificantly. The permissible levels of the overload capacity of 242/20 kV, 400 MVA power transformer was established for different values of the geomagnetically induced quasi-direct currents and the ambient temperature. It was shown that increasing of load capacity above the set values could lead the overheating of power transformer windings, followed by thermal degradation of the main insulation and an increased risk of internal short-circuits.
