Introdução aos Sistemas de Energia Elétrica

Objectives

Industrial management requires diverse skills and collaboration of engineers from different specialties. This course is intended to provide basic knowledge in electrical engineering, to enable and enhance this collaboration. The student should: Know the structure of the electricity system; Know how to characterize devices and electrical installations through lumped parameters, and be able to determine the quantities that characterize their operation at industrial frequency, either on single phase or three phase systems; Be able to determine electrical and magnetic forces; Know the principles of operation of the transformer and of the electromechanical energy conversion; Know how to apply the equivalent models of single-phase transformer and asynchronous and synchronous machines; recognize some security and protection procedures of electrical installations.

Syllabus

- Structure of the electric power system: generation, transmission and distribution. - Characterization of linear electromagnetic devices and systems by lumped parameters R, C and L: concepts and application of methodologies for their determination. Ground electrodes and safety of living beings. Electric and magnetic fields associated with electric power transmission, analysis of multi-conductor systems. Determination of the induction coefficients, analysis of magnetic circuits. - Phenomenon of electromagnetic induction. Forces calculation. - Analysis of the operation of linear electromagnetic devices and systems under AC conditions. Single-phase transformer. Three-phase systems. - Electromechanical energy conversion: generator/motor.

Prerequisites

The following prerequisites are strongly recommended: Linear Algebra, Differential and Integral Calculus, Electromagnetism.

Cross Competence Component

This Curricular Units seeks to develop, in both T and PB classes, Critical and Innovative Thinking trough the development of the critical thinking, well founded and structured and of the strategies to solve problems. The assessment percentage associated with this competence should be around 6%.

Laboratorial Component

No laboratory component.

Programming And Computing Component

Students will be challenged to use computational tools to solve more complex problems, for instance problems involving choosing the best technical and economic solution.

Ethical Principles

All members of a group are responsible for the group’s work In any assessment, every student shall honestly disclose any help received and sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
