Protective Relays and SCADA

SUB 115 delves into the critical role of protective relays in ensuring grid stability and equipment protection, alongside the fundamental concepts of Supervisory Control and Data Acquisition (SCADA) systems. The curriculum covers the operational theory, application, and settings of various relay types, including overcurrent, distance, and differential relays. Emphasis is placed on practical aspects of relay coordination and fault analysis. Concurrently, the course explores modern SCADA communication protocols, specifically DNP3 and IEC 61850, detailing their architecture, data modeling, and practical implementation in substation automation. This technician-level course prepares students for roles involving the installation, maintenance, and testing of protective relay and SCADA systems.
