Substation Communication Protocols: IEC 61850, IEC 104, DNP3 and Modbus

This course presents the full communication picture of a modern substation, from relay to control centre. Instead of memorising one protocol, you learn the logic of selecting, configuring and testing the common protocols.

Key topics

• Comparison of Modbus, DNP3, IEC 60870-5-101/104 and IEC 61850 and selection criteria
• IEC 61850 data model, logical nodes and ICD/SCD/CID files
• GOOSE and report configuration, traffic analysis with Wireshark
• Gateways, IO lists and signal mapping to SCADA
• Substation network: VLAN, RSTP, PRP/HSR and time synchronisation
• Basic cyber security and FAT/SAT acceptance testing

Audience & prerequisites

• Automation, protection and operations engineers
• Familiarity with digital relays
• Basic networking knowledge (IP, VLAN) is helpful
