Кафедра “Електричні машини” була створена в 1921 році одночасно з першим в Україні електротехнічним факультетом у Харківському технологічному інституті. Засновником факультету і кафедри був видатний вчений електротехнік професор Павло Петрович Копняєв. Перший випуск студентів кафедри відбувся у 1924 році. У подальшому, за понад сторіччя, підготовлено понад 3000 інженерів для України та зарубіжжя.

Кафедра входить до складу Навчально-наукового інституту енергетики, електроніки та електромеханіки Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 2 доктора технічних наук, 5 кандидатів технічних наук, 1 доктор філософії; 1 співробітник має звання професора, 5 – доцентів.

Calculation of the transformers and electric machines characteristics
(National Technical University "Kharkiv Polytechnic Institute", 2024-10-24) Shevchenko, V. V.; Dunev, О. О.
These guidelines are intended to perform the calculation and graphic task "Calculation of the characteristics of transformers and electric machines" in the discipline "Electric machines".
Methodical instructions, control questions and calculation task from the discipline "Foundations of Electrical Energy"
(National Technical University "Kharkiv Polytechnic Institute", 2024-10-24) Shevchenko, V. V.; Yurieva, O. Yu.
The methodical publication is dedicated to the performance of the calculation task in the discipline " Foundations of Electrical Energy" for foreign students in the specialty 141 – Electric power engineering, electrical engineering and electromechanics. The purpose of the proposed individual task is to form students' knowledge about the general electricity supply system of the country, the main stages of distribution and transmission of electric energy, knowledge about the main electrical equipment (EЕ) of power plants, substations and industrial enterprises
Formation of valeological competence in conditions of classroom and distance learning
(Харківськии̮ національнии̮ університет ім. В. Н. Каразіна, 2022) Shevchenko, A. S.; Kucherenko, Serhii; Komyshan, Anatolii; Shevchenko, V. V.; Kucherenko, Nataliia
Formulation of the problem. The article considers the problem of valeological (health saving) competence formation in non-medical students. Health saving competencies are based on a healthy lifestyle, safe behavior practices and the ability to provide emergency pre-hospital care to victims in critical situations. The formation of valeological competence in non-medical takes place during the study of valeological disciplines (including “Fundamentals of Medical Knowledge”, “Health Pedagogy” and others) in higher education institutions (HEI). Since the spring of 2019, the teaching of these disciplines is forced to take place in distance form.
Disciplines of higher education institutions that form valeological competence
(2022) Shevchenko, A. S.; Shevchenko, V. V.
Health saving issues are included in most state education standards of Ukraine. But for the full formation of valeological competence, special valeological disciplines are necessary ("Valeology", "Fundamentals of Life Safety", "Fundamentals of Medical Knowledge and Health Saving", "Health Pedagogy"). Related disciplines ("Ecology", "Occupational Safety") only partially form competence.
Improvement of turbogenerators as a technical basis for ensuring the energy independence of Ukraine
(Національний технічний університет "Харківський політехнічний інститут", 2021) Shevchenko, V. V.; Minko, A. N.; Dimov, Milen
The paper defines the directions of improving turbogenerators as the basis for ensuring the energy independence of Ukraine. The analysis of the state, problems and prospects for the development of modern electric power industry. Goal of the work is to identify promising directions for sustainable development of the national electric power industry in order to ensure energy security of Ukraine, to conduct a comparative analysis of electricity sources, to confirm the need to improve the main sources – turbogenerators. Methodology. During the research, an analytical analysis of the electricity sources, which are installed at power plants in Ukraine and the world, was carried out, taking into account the growth of the planet's population and its energy activity. Cyclic theory was chosen as the theoretical basis for forecasting. On the basis of this theory, global development trends, advantages and disadvantages of currently used sources of electricity - thermal (including nuclear) power plants and stations that operate from renewable energy sources - have been established. A review of literary sources on the methods of the energy sector forecasting the development, including the development of the energy sector in Ukraine, has been carried out. Originality. It has been established that due to the active growth of the planet's population, with the increase in its energy activity, obtaining electricity from renewable energy sources is not enough, that for the next 20-30 years nuclear power plants will be the main sources of electricity. The internal and external threats to the energy security of Ukraine, directions of development of turbogenerator construction, ways to improve turbogenerators, to increase their energy efficiency, power per unit of performance, to increase the readiness and maneuverability factors, and overload capacity have been identified. Practical significance. The need to continue the modernization and improvement of the turbogenerators of nuclear power plant units, as the main sources of electricity, has been proved. The directions of their improvement are established: increasing the power in the established sizes, making changes to the design of the turbogenerators inactive elements, replacing the cooling agent to keep Ukrainian turbogenerators at the world level, improving auxiliary systems, improving and increasing the reliability of the excitation system, introduction of automatic systems for monitoring the state turbogenerators. Possible limits of use, advantages, disadvantages and problems of using renewable energy sources for Ukraine have been established.
Calculation of the transformers and electric machines characteristics
(National Technical University "Kharkiv Polytechnic Institute", 2021) Shevchenko, V. V.; Domochka, Lidiia Vladyslavivna
This edition is dedicated to the implementation of calculation task "Calculation of the transformers and electric machines characteristics" on the discipline "Electric machines". The purpose of this discipline is to consolidate theoretical knowledge and develop practical skills for calculating the characteristics of transformers, alternation current (AC) electric machines and direct current (DC) electric machines. The objects of study are transformers and electric machines, which are the basis of electric power in various industries. The subject of this discipline are the electric machines, which are used in practice to convert one form of energy into another: mechanical energy to electrical (the generators), electrical energy to mechanical (the engines), and power transformers, which are used to convert the meanings of alternating current and voltage. After training, the student must know the structure, basic elements of the transformers and electric machines, there operation principle and characteristics, peculiarities of motors starting, the ways of rotation frequency control and braking. The student should be able to evaluate new electrical equipment, take into account technical and economic requirements. This assignment consists of five tasks. For each part, control questions and tasks are formulated, recommendations for their solution are given. Calculation tasks are the student’s final document to complete the discipline. The report on the done work must be finished in written form and defended by the examination date. The tasks and the volume of the work must be agreed by the lecturer of this discipline. The report should begin with a cover page, the sample of which is given in Appendix A. When drawing up a report, it is necessary to formulate the task, show the procedure for performing calculations: write down a formula, and then put numbers in this formula and show the result of the calculation. The report should contain the necessary diagrams and graphs. At the end of the report student has to give the list of information sources used in the work. Graphs and diagrams should be built on graph paper, indicating the scale and dimension of the physical quantity on the axes. If the graph was built on a regular sheet of paper, then a uniform "grid" should be drawn on the graph field. Students choose the number of a variant for the work according to the number in the academic group list. New modern notation symbol system of electrical, magnetic, mechanical and energy values, which correspond to the state standards, are used in this study course.
