Coordination of Directional Over-Current Relays using MATLAB/Simulink and Their Integration into Undergraduate Power System Protection Courses

摘要

This paper describes MATLAB/Simulink implementation of Coordination of Directional Over-Current Relays (DOCR) using 3 bus and 4 bus test models. These simulation models are developed to support and enhance Power System protection courses at the undergraduate level. This study helps students to acquire a clear understanding of this topic.
