Power System Protection: Protective Relay Logic

Power System Protection: Protective Relay Logic

This course is part of a multi-part course series about one of the main areas of power engineering: power system protection and control. Power system protection and control ensures the reliable continuous operation of power systems and is therefore an essential area of power engineering. In this course of the multi-part course series, you will learn how to implement digital logic in protective relays. The course is divided into the following sections:

1. Introduction to Protective Relay Logic: we will begin in section 2 of the course by introducing logic gates and how they work. We will also be discussing the order of operation of logic functions and how to develop truth tables to determine proper operation of logic schemes. We will finish the section by discussing some functions commonly used in protective relay logic: timers, latches, and edge triggers.

2. Applications of Logic in Protective Relays: having defined the fundamentals of relay logic, we will move into developing practical examples in section 3 of the course. We will be taking a look at how to build five different logic schemes: enable/disable switches, permissive tripping schemes, overcurrent blocking schemes, breaker failure schemes, and automatic reclosing schemes.

By learning how to use digital logic in power system protection and control, you will be able to continue your study of power systems for a career in power engineering and electrical engineering.

Remember that Udemy offers a 30-day money-back guarantee. I am also always available for questions while you go through the course to ensure everything is clear.

See you in the course!
