IEC61850 Generic Object Oriented Substation Event - GOOSE• Device to multi-device communication – Local or Wide Area
•Bridgeable but Non-routable
•User-defined Dataset sent in an Ethernet Multicast message
•Message sent on change of state as well periodically to enable detection of device failure
• Reliability effected through message repeat
GOOSE Header:• Multicast Address
•Name
•Time Until Next GOOSE
•Etc.
User-Defined Dataset• Status Information
•Analog Values
•Data Quality
•Time

SCL – Substation Configuration Language
• Description language for communication in electrical substations related to the IEDs
• XML based language that allows a formal description of
– Substation automation system and the switchyard and the relation between them
– IED configuration

SCL File Types
SSD: System Specification Description. XML description of the entire system.
SCD: Substation Configuration Description. XML description of a single
substation.
ICD: IED Capability Description. XML description of items supported by an IED.
CID: Configured IED Description. XML configuration for a specific IED.

Benefits of IEC61850• High-level services enable self-describing
devices & automatic object discovery saving $$$$$ in configuration, setup and maintenance.
• Standardized naming conventions with power system context eliminates device dependencies and tag mapping saving $$$$ in config., setup, and maint.
• Standardized configuration file formats enables exchange of device configuration saving $$$$ in design, specification, config., setup, and maint.

Benefits of IEC61850 - 2
• Higher performance multi-cast messaging for inter-relay communications enables functions not possible with hard wires and save $$$$ in wiring and maintenance.
• Multi-cast messaging enables sharing of transducer (CT/PT) signals saving $$$$ by reducing wiring and connection costs
