Power Protection
Overview
This unit aims to provide the concepts and principles of electrical protection techniques in today's power systems. The unit also covers different types of protection systems, application of protection to generators, motors, transformers, and electrical system communications for protection application in of modern electrical energy system. Students will learn to analyse and detect different types of faults in power systems.
Requisites
Learning outcomes
Students who successfully complete this unit will be able to:
- Describe the concept and principles of electrical protection systems (K2,K3,S1,S2)
- Appraise and apply calculation methods for magnitude and angle of voltage and current for the digital relaying (K2,K3,S1,S2)
- Calculate symmetrical/un-symmetrical fault currents, and analyse different fault detection techniques (K2,K3,S1,S2)
- Design and coordination of overcurrent / directional overcurrent protection (K2,K3,S1,S2,S3)
