Power System Protection

Power System Protection

Course Date

11/3/2019 To 11/7/2019

Course Description

This course aims at providing participants with fundamental understanding of power system protection and design. It involves an introduction to power-system fault calculations, review of protection principles and relaying with reference to relevant international standards and a study of fundamental practices in generator protection, transformer protection, line protection, motor protection and pilot relaying.

Learning Outcomes: 

At the end of this course, participants should be able to:     

  1. Gain an up to date knowledge on power system protection schemes and related standards
  2.  Familiarize with techniques to calculate out short-circuit currents   
  3. Apply protection principles to design protection for electric power equipment and systems
  4. Model power system protection and coordination schemes using industry-standard software ETAP                                                                            
  5. Acquire hands-on experience of protection relays and power system hardware simulator

Course Outline:

Course topics include: Introduction to power system faults, Short-circuit current calculations in AC systems, Review of standards, Protection principles, Relay Technology, Overcurrent Protection, Unit protection, Distance protection, Transformer/Generator/Motor protection, Industrial power system protection, Control and limitation of short-circuit currents. Morning sessions are lectures and worked examples, with afternoon sessions dedicated to hands-on experiments and power system protection case study using ETAP software.
