Relay Protection Course: Implementation of Digital Logic and Schemes in Protective Relays

Learn how to implement protective relay logic and how to build logic schemes of enable/disable switches, permissive tripping, overcurrent blocking, breaker failure, and automatic reclosing. The course consists of 13 lessons in 2h 16m total length.

Course Description

In this course, you will learn how to implement digital logic in protective relays and how to build logic schemes of enable/disable switches, permissive tripping, overcurrent blocking, breaker failure, and automatic reclosing. Power system protection and control ensures the reliable continuous operation of power systems and is, therefore, an essential area of power engineering.

The course consists of 13 lessons in 2h 16m total length and it’s divided into the following sections:

Introduction to Protective Relay Logic

We will begin the course by introducing logic gates and how they work. You will learn the operation order of logic functions and how to develop truth tables to determine the 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.

Applications of Logic in Protective Relays

Having defined the fundamentals of relay logic, we will move into developing practical examples. 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.
