Sistemas Elétricos Industriais

The teaching and learning methodologies adopted in this course are designed to foster active student engagement, critical thinking, and the practical application of theoretical concepts within the field of Industrial Electrical Systems. Grounded in principles of active and collaborative learning, the methods are organised sequentially to support the acquisition of fundamental theoretical knowledge, the completion of applied exercises, and the analysis of practical case studies.
During lectures, the expository method provides students with a structured introduction to core concepts. This is complemented by active learning sessions, undertaken individually or in small groups, which reinforce comprehension and encourage participation. Where relevant to the course objectives, study visits, guest lectures, and seminars may also be incorporated.
In practical classes, students undertake application exercises and guided reflection activities, consolidating their knowledge through problem-solving tasks and the examination of real-world scenarios.
Furthermore, two mandatory group projects will be undertaken, requiring the analysis, design, and presentation of solutions to specific technical problems. The presentation of results to peers is intended to stimulate critical discussion and further consolidate the knowledge acquired.

Calculate electrical quantities in alternating current (AC) systems and interpret the results.
Identify the primary sources of energy and evaluate their importance for electricity generation, analysing the processes of conversion between different forms of energy.
Analyse the structure of electrical networks and explain the technical feasibility of the coexistence of alternating current (AC) and direct current (DC) networks.
Classify and characterise the different loads found in industrial electrical networks, particularly electric motors and their associated drives.
Explain the principles of installation, sizing, and protection of industrial electrical networks, relating them to protection systems against direct and indirect contact.
Evaluate risks and describe the procedures required for safe interventions in electrical networks.
Interpret tariff regimes, analyse components of energy bills, optimise costs, and propose alternatives to reduce them and promote energy efficiency.
