Analysis of design features of inductive electromagnetic current limiter
(НТУ "ХПІ", 2019) Goncharov, Evgen Viktorovych
The design circuits of an electromagnetic short-circuit current limiter of inductive type with movable armature and moving core are considered. A comparative analysis of the design features of the electromagnetic current limiter with copper or superconducting winding is carried out. The operation principle of the electromagnetic short-circuit current limiter of inductive type with copper or superconducting winding is considered. The peculiarities of operation modes of the electromagnetic short-circuit current limiter of inductive type with copper or superconducting winding are analyzed. Using results of the mathematical modeling of the magnetic system of the electromagnetic short-circuitcurrent limiter by the Finite Element Method in the FEMM software environment, the character of the distribution of the magnetic flux density in the nominal mode and in the current limiting mode is determined, which allows to determine the parameters of the current limiter and design features. In accordance with the design features of the electromagnetic short-circuit current limiter of inductive type, the sequence of calculation of the basic parameters of the magnetic system, taking into account the voltage drop factor, is given. The basic equations of the electric equilibrium of the voltage drop of the electromagnetic short-circuit current limiter of inductive type for nominal mode and short-circuit conditions are given. The use of the design circuit of the electromagnetic short-circuit current limiter with superconducting winding can provide energy-saving in nominal mode. The use of high-temperature superconducting wire due to increased critical parameters will ensure preservation of the superconducting state of the winding in short-circuit mode.
Analysis of modern power efficient systems development strategies
(Національний технічний університет "Харківський політехнічний інститут", 2020) Goncharov, Evgen Viktorovych; Polyakov, I. V.; Markov, V. S.; Kryukova, N. V.; Boykov, D. A.; Skrebtsov, N. K.; Tsebriuk, I. V.
The article analyzes the existing methods and ways of developing and improving information and energy systems and grids. A number of questions are analyzed regarding the prospects for the development of information and energy systems and power lines. It has been determined that the basis of the electric power industry is the integrated energy system, which provides centralized energy supply to domestic consumers, interacts with the energy systems of neighboring countries, and ensures the export and import of electric power. It is concluded that in recent years, the so-called “cloud technologies” have become increasingly popular. From an analysis of the current state of the electric power industry, it follows that the need for its modernization and improvement. Accordingly, in connection with the transition of the world electric power industry to energy-efficient technol ogies, the main attention should be directed to studying the connection between the processes of transmission and distribution of electric power, as well as the related “smart” measurements, issues of the operation of energy markets and the operation of regulatory standards. It was noted that with the creation of the concept of “smart grids”, it is important to develop appropriate regulatory and technical support for the integration of dispersed energy sources using existing modern power electronics devices and storage devices, which will lead to the creation of a capacity management platform based on modern technologies. It is noted that the possibility of functioning in real time is provided due to the specific organization of the information grid, rather than an electric grid, which is provided due to the specific organization of the information grid. The results of the analysis indicate that the control information center must have sufficient computing power and bandwidth of the computing grid as well as spare computing power capacities to permanent operability assurance.

Synthesis aspects of cryogenic high-temperature superconducting shielding inductive short-circuit current limiter
(NTU "KhPI", 2016) Dan’ko, Vadymir Grigorovich; Goncharov, Evgen Viktorovych
The short-circuit current limiter of inductive type with the high-temperature superconducting winding and screen is considered. The basic design parameters of the magnetic system were determined and features of the transition process at the initiation of short-circuit were analyzed.
