IEC 61850 Protocol Part-2: Advanced Level – Report Mechanism

Take your IEC 61850 knowledge to the next level with this comprehensive advanced course dedicated to the Report Mechanism used in modern Substation Automation Systems.

This course provides an in-depth understanding of how IEC 61850 reports are configured, generated, transmitted, and analyzed in real-world utility applications. Through detailed explanations, practical demonstrations, configuration examples, protocol analysis, and Wireshark packet captures, you will gain the skills required to confidently configure, troubleshoot, and optimize IEC 61850 reporting services.

Whether you are a Protection & Control Engineer, SCADA Engineer, Substation Automation Engineer, Testing & Commissioning Engineer, or a power system professional, this course will help you build a solid understanding of Report Control Blocks (RCBs), DataSets, MMS communication, trigger conditions, and advanced reporting concepts used in digital substations.
