Protection of Electrical Power Systems

ABOUT THE COURSE
Power system protection is an essential component of all forms of electrical power systems. In practice, protective relaying is directly associated with security of supply, the reduction of damage to faulted plant, cost of energy and, most importantly, all aspects of safety. The subject is unique in requiring knowledge of all topics broadly classified under the title of electrical power engineering, including generation, utilization, maintenance and the transmission of electrical power. As a consequence it enhances an engineer’s working knowledge and becomes an important asset for power system planning, operation and management .
The course focuses attention on the fundaments of the subject and illustrates the protection philosophies in common use by reference to the application of modern multi-functional microprocessor relays to practical situations illustrated by case studies .

YOU WILL LEARN
Upon Completion of this Course, participants will have knowledge about :

  • The need for protection
  • An overview of power system fault analysis
  • Protection fundamentals
  • Relay transducers, both current and future
  • System grounding principles
  • Over current earth fault protection
  • Coordination principles
  • Transformer protection
  • Generator protection
  • Bus protection
  • Motor protection
  • Line and feeder protection
  • Principles of relay application

DESIGNED FOR
The aim of the course is to update the working knowledge of practicing protection engineers and senior technicians as well as those in closely related branches of electrical power engineering responsible for specification, installation, inspection, and maintenance and commissioning of electrical plant

Training Methodology :
The opening sessions of the course deal with the fundamentals of protection equipment, basic technologies used and a resume of fault analysis. The course then goes on to describe in detail various applications associated with the different types of apparatus used in the electrical power industry. This is followed by a guide to “good practice” drawn from many practical situations experienced by practicing engineers and manufacturers of plant .
