Course Creation: June 2026
Instructor: Dr. Saeed Roostaee
Duration: 7 Hours 15 Minutes (Growing with Free Future Updates)

Course Overview

Modern substations are rapidly evolving from conventional control systems to fully digital Substation Automation Systems (SAS). This practical course provides a comprehensive introduction to SAS concepts, architectures, control philosophies, and engineering principles used in modern substations.
You will learn the differences between conventional and digital substations, understand protection and control panels, study station and bay architectures, and explore the control logic and signals used in real-world SAS projects.
This course also serves as the recommended foundation for advanced training, including:
– Siemens SIPROTEC 4 Bay Control Unit (BCU)
– Siemens SIPROTEC 5 Bay Control Unit (BCU)
– SICAM PAS
– SICAM SCC
– IEC 61850 for SAS Engineers
