Sistemas Elétricos e Qualidade de Serviço

Linear Algebra, Calculus, Electrical Circuit Theory

The teaching methodologies, that promote active and collaborative learning, follow a temporal sequence that enables students to acquire theoretical concepts, solve a set of exercises and carry out practical case studies.

– introduce the concept of Electric Power System and its structure: generation, transmission, distribution and supply.

– provide the basic concepts underlying both the conventional processes of conversion of the different forms of energy in electrical power and renewable sources.

– present the mathematical concepts, necessary to the modelling of Electric Power Systems, in the steady state.

– introduce the concept of Power Quality in Electric Power Systems: Commercial Quality, Continuity and Quality of the Wave (Sags and swells, Transient overvoltages, Harmonics, Voltage regulation).

– Characteristics of the Portuguese electrical energy system.
– Electric energy sources (thermal and hydric power plants, renewable energy)
– Electric Power Demand.
– Power diagram.
– The three-phase system.
– Power Transportation and Distribution.
– Calculate the electric parameters of lines, set the PI model
– Per unit system.
– Power Flow Computations in Electric Power Systems.
– General aspects regarding Quality of Service:
– Quality of the Wave;
– Continuity
– Commercial Quality;
– Legislation and Recommendations;
– Analysis of Case Studies.

The subject assessment can be carried out during the semester or in a final exam. All students enrolled in the curricular unit have access to continuous assessment tests.

 Continuous assessment

First assessment, TE1: Theoretical Part 50% and Theoretical-Practical Part 50%

Second assessment, TE2: Theoretical Part 50% and Theoretical-Practical Part 50%

CF (Final grade) = 0.5 TE1 + 0.5 TE2

Assessment by Exam

Exam - Theoretical Part, ET

Exam - Theoretical-Practical Part, ETP

CF (Final grade) = 0.5 ET + 0.5 ETP

For students covered by special regimes, who are unable to attend classes, an appropriate methodology will be defined with clarification of doubts during office hours.

Students with Special Educational Needs will be assessed in ways or conditions appropriate to their situation, without jeopardizing the correct assessment of the skills and knowledge to be  evaluated.
