Protection and Control of Electrical Power Systems

Ficha de unidade curricular - Ano letivo 2019/2020

Teaching language

Portuguese

Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

The student will be able to analyze and project Protection Systems and Network automations of electrical networks, as well as, to develop protection systems to electrical distribution power lines, farm wind, photovoltaic and electrical machinery. The student should also be able to define criteria to an adequate regulation of protection systems and to identify and analyze the response of these systems to different network or machinery faults.

Syllabus

1) General Considerations
- Economic and legislative considerations about protection systems applied to electrical networks and to producers under special rules – renewable energy
2) Measurements transformers
- Current transformers and Tension transformers
- Capacitive and optical transformers
3) Protection of electrical networks (power lines of transportation and distribution)
- Protections against phase-to-phase faults and against phase-to-earth faults.
- Distance and Differential protection
4) Protection of electrical machines/machinery
- Protection of transformers, generators and motors
- Differential protection, Buchholz’s and Thermic imaging protection
5) Smart grids and automatic regulation of electrical power systems
- Monitoring of the potency generated by the distributed power
- Disturbance of the network and the existence of harmonics
6) Automation and telecontrol systems
- Architecture of the remote systems
- System control and data acquisition – SCADA

Demonstration of the syllabus coherence with the UC intended learning outcomes

a) Lectures: Interactive exhibition and demonstration method;
b) Practical Classes: Solving problems with relevant interest
c) Laboratory Classes: experimental method applied to the development of circuits and systems based on the knowledge acquired in the theoretical and practical lessons.

Teaching methodologies
