OVERVIEW

The teaching of "Electric Systems for Energy" is of very important in the  background of an energy engineer, who needs in-depth knowledge on the production, distribution and use of electricity topics and who must be able to manage optimally processes based on the use of electricity.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide the basic knowledge of circuit theory and functional aspects of electrical systems, with the aim of grasping the links between the general principles, the physical reality of the phenomena described and the technological applications

AIMS AND LEARNING OUTCOMES

The teaching would like to provide the basic knowledge of the theory of circuits and  to analyse aspects of electrical systems, with the aim of linking together the general principles, the physical of the phenomena described and the applications at industrial level.

This basic knowledge will be of fundamental importance to the student in his subsequent training teaching in the energy engineering sector, since themes today of strong industrial and social interest, such as modelling of renewable energy sources, smart grids and energy management systems, can not disregard the bases provided by the teaching of Electrical Systems for Energy.

At the end of the teaching-unit the Students will be able 

• To use the basic methods for Linear, Time Independent and Lumped Parameter Circuit Analysis for solving electrical circuits.
• To solve circuits both in time-domain (Resistive-Only DC, Transient Analysis), as well as in  frequency domain (Steady State AC).
• To solve three-phase systems balanced and not, by using the power method as well as the symbolic one.

PREREQUISITES

The teaching-unit does not require particular prerequisites. In the same time, Students should know the basis of algebric computation with real and complex numbers and the meaning of linear differential equation of firsrt and second order with constant coefficients.

TEACHING METHODS

Theory lectures and related exercises.  All the lectures will be organized in frontal mode. 

The lessons will be held in the classroom in frontal mode. There will be team-working activities during which it will be possible to work on alphabetic-functional competence.

Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's disability liaison at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns.

SYLLABUS/CONTENT

EXAMS

EXAM DESCRIPTION

The final assessment consists of both a written examination and an oral examination, which must be taken within the same examination session. During these assessments, students will be required to solve electrical circuits under steady-state conditions, transient (dynamic) regimes, and sinusoidal operating conditions, including both single-phase and three-phase systems. They will also be expected to demonstrate a thorough knowledge and understanding of the principal theoretical topics covered throughout the course.

The written examination is deemed to have been passed if the student achieves a score of at least 16/30. Admission to the examination is contingent upon prior registration, which must be completed no later than five days before the examination date through the UNIGE Online Services portal, under the section “Students – Exam Registration”.

The oral examination will be conducted within the same examination session as the written examination, if this one is passed. Any exceptional circumstances preventing a student from attending the oral examination during the scheduled session, provided that such circumstances are duly justified and supported by appropriate documentation, will be considered on a case-by-case basis by the Examination Board.

The final grade is determined as the arithmetic mean of the marks obtained in the written and oral examinations.

ASSESSMENT METHODS

The evaluation of students’ learning outcomes is based on continuous monitoring of participation and interaction during teaching activities, on performance in practical exercises involving the solution of elementary electrical circuits, and on the overall verification conducted during the oral examination.

Detailed information regarding examination preparation and the relative importance of individual topics for assessment purposes will be provided during lectures and exercise sessions.

The written examination is designed to assess the acquisition of fundamental knowledge, with particular emphasis on the practical skills required for the analysis and solution of electrical circuits operating under steady-state, dynamic, and sinusoidal conditions, in both single-phase and three-phase systems. Students are expected to answer the proposed questions correctly and with rigorous justification, presenting clear, orderly, and coherent solutions in which all quantities employed are properly defined. Assessment will take into account both the correctness of the solution methodology and the accuracy of the numerical results obtained.

The oral examination will focus primarily on the theoretical and practical topics covered during lectures and exercise sessions. Its purpose is not only to evaluate the student's level of knowledge and understanding, but also to assess the ability to critically analyze and independently discuss the topics proposed during the interview. Students may be required to state, prove, and apply the principal theorems presented throughout the teaching.

Additional assessment criteria include precision of exposition, clarity of argumentation, the ability to critically elaborate and integrate the acquired knowledge, and the use of appropriate and rigorous technical terminology in the presentation of the required concepts.

Students with a certified learning disability (DSA), a disability, or other special educational needs are invited to contact the instructor at the beginning of the course to discuss teaching and examination arrangements that, while respecting the learning objectives of the course, take individual learning needs into account and provide appropriate accommodations.
Please also note that requests for exam accommodations or exemptions must be submitted using the form available at this link
