Class Electrical Energy Systems

The main objective of this course is to develop the capacity of analysis and design of three phase
systems from the production to the transmission and distribution of electricity:

1. Power sources and electrical power systems.
2. Historical evolution of electric power systems.
3. Fundamental concepts of electric power systems.
4. Operational Considerations.
5. Characterization and determination of the electrical parameters of the power transmission temples (longitudinal resistance and inductance, transverse admittance and capacity); Long line equations; Modeling of lines by diport and equivalent circuit in Pi; Voltage and current profiles along the lines; Power Limit
6. Introduction to steady state power systems. Brief introduction to the criteria underlying the energy flow equations.

There are two types of evaluation:

• Continuous assessment - two exams, during the regular class period, each one weighing 40% in the final evaluation. The evaluation obtained in the laboratory component, with a weight of 20%, also contributes to this modality. It should be noted that, in this aspect, approval is only possible if the average obtained in both written frequencies is greater than or equal to 10 values, and there is also the possibility of resorting to a Global Test.
• Exam - Exam test as defined in the general assessment regulations (80%) + Lab test (20%).

Note: In addition to the Continuous Assessment and the Exam, there will be an oral test (which can be
waived by students with high attendance and positive participation in classes).
