Документ Calculation of electric field distribution in the vicinity of power transmission lines with towers and unmanned aerial vehicles presence(Інститут електродинаміки НАН України, 2018) Rezinkina, M. M.; Sokol, Yevgen I. ; Gryb, O. G.; Bortnikov, A. V.; Lytvynenko, S. A.The results of mathematical modeling of the electric field of overhead power transmission lines (TL) are presented taking into account presence of towers and unmanned aerial vehicles (UAVs) for various cases of the TL lines layout: vertical, horizontal and triangular. Numerical calculations of electric field (EF) were performed using finite integration technique and uniaxial perfectly matched layer. In this case the TL lines under the electrical potential were replaced by linear charges located on their axes. The obtained numerical results for the case of towers and UAV absence were compared with the analytical solutions, which showed coincidence of the EF strength moduli within the range of the assigned accuracy of the numerical calculations– 3%. The results of calculations are necessary to determine the flight height of UAVs, safe from the point of view of electromagnetic compatibility of the on-board electronics to influence of the TL EF and TL towers.Документ Guidelines for the calculation of the individual assignment: "The Laplace transform analysis of transient processes in linear electrical circuits"(National Technical University "Kharkiv Polytechnic Institute", 2022) Rezynkina, M. M.; Kostiukov, I. O.; Lytvynenko, S. A.Документ Guidelines for the calculation of the individual assignment "The analysis of transient processes in the linear electrical circuits"(National Technical University "Kharkiv Polytechnic Institute", 2022) Rezynkina, M. M.; Kostiukov, I. O.; Lytvynenko, S. A.These guidelines contain general theoretical provisions concerning the topic: "The analysis of transient processes in the linear electrical circuits", as well as the examples of solutions for the typical problems and the list of the individual assignments. These assignments constitute the basis, which allows the students to gain skills in practical application of theoretical knowledge in the field of the analysis of transient processes in the linear electrical circuits. The necessity of the transient processes analysis is caused by the fact that such analysis allows us to detect various surges of voltage and current, which can lead to the emergencies as well as to damage of the equipment subjected to these surges. Transient processes can also lead to the distortions of signals during their transition through the impulse electronic circuits. The guidelines are intended for the students studying the electrical engineering and computer sciences.Документ Guidelines of calculation and graphical performing the task on the topic "Calculation of linear DC electric circuits"(Видавничий центр НТУ "ХПІ", 2020) Rezynkina, M. M.; Kiessaiev, O. H.; Rezynkin, O. L.; Lytvynenko, S. A.These guidelines contain the necessary theoretical basis, tasks and examples of calculations of linear DC electric circuits. The task is on the topic "Linear DC electric circuits" of the first semester of students' study of the courses: "Theoretical Basics of Electrical Engineering", "Theory of Electrical and Magnetic Circuits", "Theory of Electric Circuits". The first semester of students’ study in these courses is significant for further study of both theoretical basics of electrical engineering and other specialized disciplines of electrical engineering, for which theoretical basics of electrical engineering are the basic discipline. During the first semester, students learn the basic laws and methods of calculation of DC and AC circuits (Ohm's and Kirchhoff's laws, mesh current method and nodal potentials methods, the equivalent generator method and the superposition method), which are the base for practical calculations of electric circuits for various purposes. Self-study students’ work by this task should be considered as the basis for successful learning in the next semesters. At this task performance, students can use sources at the end of the guidelines, which contain the theory and examples of the considered problems solution. Guidelines are for students of specialties 141, 151, 171 of full-time and distance forms of study.Документ Guidelines of calculation and graphical performing the task on the topic "Linear electric circuits of harmonic current"(2020) Rezynkina, M. M.; Kiessaiev, O. H.; Rezynkin, O. L.; Lytvynenko, S. A.The methodical instructions are intended for students of the specialties 141 "Electric Power, Electrical Engineering and Electromechanics", 151 "Automation and computer-integrated technologies", 171 "Electronics" of full-time and distance forms of study.
