Документ Structuring overhead lines 35 – 750 kV in accordance with the concept Smart Grid(GS publishing service Sherman Oaks, Los Angeles, 2021) Cherkashyna, V. V.The presented article is devoted to the study of processes affecting the transmission of electricity. The study uses a discounted cost model for 35 - 750 kV overhead lines, which is improved by changing the analytical relationship of investment to wire cross-section. To analyze this model, a criterial method is used that allows decision making in relative units with incomplete initial information. In the course of research it was found that improving the structure of overhead lines 35– 750 kV by optimizing the parametric series of wires reduces the effect of network heterogeneity. The proposed direction has a number of features, in particular, it shows a consistent improvement in the structure of lines. In comparison with similar well-known approaches, the advantage of the proposed approach is that it allows to bring the energy facility for subsequent equipping with monitoring systems and control of the line operation parameters in accordance with the concept Smart Grid.Документ Substantiation of parametric series of overhead lines wire cross-sections in conditions market and insufficient initial information(Товариство польських інженерів електротехніки та електроніки, 2017) Lezhniuk, P. D.; Cheremisin, M. M.; Cherkashyna, V. V.; Denisova, N.; Smolarz, A.; Abdreshova, S.One of directions in developing overhead lines in conditions market and insufficient initial information by optimizing parametric series of wire cross-sections has been substantiated. An optimization criterion of parametric series of wire cross-sections has been formed, recommendations on unification of overhead lines have been offered.Документ Adjustment of air line structure for optimal transport management and electricity distribution(PC тесhnology сеntеr, 2018) Cherkashyna, V. V.The object of research is processes in air lines that affect the transportation and distribution of electricity. One of the most problematic places is the wires of overhead lines. The variety of wires with which the lines are made leads to heterogeneity of the network, which is reflected in the technological losses of power. In the course of the study, the technical and economic model of discounted costs in air lines is used, which is improved due to a change in the analytical connection of investments with wire cross-section. A criteria method is used to analyze this model. This method allows to analyze such models and to make a decision in relative units with incomplete initial information. It is received that perfection of structure of overhead lines at the expense of optimization of parametrical series of sections of wires allows to reduce influence of heterogeneity of a network. And also to proceed to the unification of overhead lines, to increase the schedule for the reconstruction of the facility, but does not expand the functionality of the lines. Equipping the lines with a fiber-optic monitoring system allows to monitor the parameters of the object along the entire length of the object. This reduces the loss of active power and provides an opportunity to optimally manage the transport and distribution of electricity in real time. The proposed direction has a number of features, in particular, shows a consistent improvement in the structure of the lines. In comparison with similar known approaches, the advantage of the proposed approach is the complex justification of the development of overhead lines in the electricity market.Документ Technical-economic justification electric network 110 kV(Aladdin-print, 2021) Danylchenko, D. O.; Dryvetskyi, S. I.; Cherkashyna, V. V.; Shevchenko, S. Yu.The implementation of the course project for the course "Electrical Systems and Networks" is an important stage in the training of electric power specialists, which is due to the need for a comprehensive review and solution in these developments of a large group of technical and economic issues related to the operation of electric networks. The guidelines contain information about the order of the course project, the main ratios for performing electrical and technical and economic calculations, recommendations on the use of standard design solutions.Документ Electrical systems and networks(2019) Danylchenko, D. O.; Dryvetskyi, S. I.; Cherkashyna, V. V.; Shevchenko, S. Yu.Designed to clarify the sequence of calculating the course project in the discipline "Electrical Systems and Networks" students of foreign education. The basic disciplines for successful mastering of the program material during the practical training are: algorithmization and software, theory of automatic control, distribution electrical networks. These guidelines provide for the formation of the following competencies: the ability to improve existing technological systems and find the best methods for their operation; ability to carry out research by methods of classical sciences, planning, organize and carry out scientific researches in the field of electric power, electrical engineering and electromechanics.
