Protection of Electrical Power Systems



Introduction:


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. 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.
