Мета вивчення дисципліни: The purpose of teaching the discipline "Theoretical foundations of electrical engineering" is the formation of a scientific worldview, an appropriate system of views on the essence of physical phenomena accompanying the electromagnetic processes of electrical engineering devices and systems, providing theoretical foundations for the study of specialized electrical engineering disciplines.
Завдання: The study of an academic discipline involves the formation and development of students' competencies: general: • ability to analyze and synthesize; • the ability to search, analyze and critically evaluate information from various sources; • the ability to communicate effectively at the professional and social levels; • creativity, ability to system thinking; • understanding the need for lifelong learning and the transfer of acquired knowledge professional: • the ability to apply information and communication technologies and programming skills to solve typical engineering tasks; • the ability to apply professional knowledge and practical skills to create new and maintain existing electrical, electrical, and electromechanical systems and their components; • the ability to apply analytical methods of analysis, mathematical modeling and perform physical and mathematical experiments to solve engineering problems and when conducting scientific research; • the ability to critically analyze the main performance indicators of the system and evaluate the used technical solutions and equipment; • the ability to integrate knowledge from other disciplines, apply a systemic approach and take into account non-technical aspects when solving engineering problems and conducting research; • the ability to design systems and their elements independently, taking into account all aspects of the given task.
Learning outcomes: • to know the basic concepts and laws of the electric circuits; • the ability to choose optimal method of analysis of steady-state modes in linear electric circuits (DC, AC, non-sinusoidal and three-phase circuits); • the knowledge of basic theory of multipolar and four-polar elements, operation principles and structure of the electric filters; • ability to apply mathematical methods and computer simulation to solve practical problems of electrical engineering; • ability to apply the circuits theory for the special subjects studying and for the design and service of electrical devices and systems.
Required prior and related subjects: • Further Mathematics, • Physics; • Fundamentals of Programming and Software for Engineering Calculations.
Summary of the subject: The bases of the theory of linear electric circuits. Elements of electric circuits, their parametrs and mathematical models. Methods of the electric circuits analysis. Symbolic method of electric AC circuits analysis. Electric circuit of periodical non-sinusoidal current and features of their calculation. Three-phase circuits and their analysis. The bases of the multipolar elements theory. Passive four-polar elements and their description. Electrical filters.
Опис: In the first part of the discipline "Theoretical basics of electrical engineering", the basics of the theory of linear electric circuits and methods of their analysis are considered. The main sections here are: linear electric circuits of constant, sinusoidal and non-sinusoidal currents, three-phase circuits and the basics of the theory of multipoles. The discipline takes into account the peculiarities of the training of bachelors and masters of all specializations, which correspond to the specialty "Electroenergetics, electrical engineering and electromechanics".
Assessment methods and criteria: • Computational task, written reports on laboratory course, oral questioning (30%); • final control (control event – exam): written and oral form (70%).
Критерії оцінювання результатів навчання: Assessment of knowledge is provided by current control and semester control. Current control – preparation, execution and defense of laboratory work, execution and defense of calculation and graphic work. Examination control is carried out during the session in written and oral form.
Порядок та критерії виставляння балів та оцінок: 100–88 points – (“excellent”) is awarded for a high level of knowledge (some inaccuracies are allowed) of the educational material of the component contained in the main and additional recommended literary sources, the ability to analyze the phenomena being studied in their interrelationship and development, clearly, succinctly, logically, consistently answer the questions, the ability to apply theoretical provisions when solving practical problems; 87–71 points – (“good”) is awarded for a generally correct understanding of the educational material of the component, including calculations, reasoned answers to the questions posed, which, however, contain certain (insignificant) shortcomings, for the ability to apply theoretical provisions when solving practical tasks; 70 – 50 points – (“satisfactory”) awarded for weak knowledge of the component’s educational material, inaccurate or poorly reasoned answers, with a violation of the sequence of presentation, for weak application of theoretical provisions when solving practical problems; 49-26 points - ("not certified" with the possibility of retaking the semester control) is awarded for ignorance of a significant part of the educational material of the component, significant errors in answering questions, inability to apply theoretical provisions when solving practical problems; 25-00 points - ("unsatisfactory" with mandatory re-study) is awarded for ignorance of a significant part of the educational material of the component, significant errors in answering questions, inability to navigate when solving practical problems, ignorance of the main fundamental provisions.
