Objectives

This course aims to develop essential knowledge and capacity in the domain of power system protection.  This includes, for example the ability to design and customize protection systems and equipment against incidents in electrical power systems.  The module will start with presenting basic principles of relays and requirements of the protection and control in power systems.  Following from there, the distribution and transmission fault clearance and post-fault are discussed.  The module will finish with discussion on various aspects related to the protection of rotating machines and transformers. 

Learning outcomes and competences

1. the acquisition and demonstration of advanced knowledge on the constitution and performance of power protection in electrical energy systems
2. the treatment, validation and interpretation of results obtained in practical assignments, namely in the parameterization and programming of digital relays
3. Autonomous work and bibliography research
4. Planning team work and developing team spirit
5. Report writing; 
6. The understanding of external, enterprise and commercial contexts in which this sector power system protection

7. Setting objectives and project management

Teaching methods and learning activities

Theoretical exposition classes supported on transparencies.

Development themes:

Working examples will be used to facilitate developing the ability to apply theories.  Students will be grouped (2-3 students a group) and will be required to prepare and present their proposed solutions in class.  Their proposed solutions will be archived for future reference.
