Generic Substation Event Basics

The Generic Substation Event is a service class that has been designed to transmit data for time critical functions such as trip signals to circuit breakers. Its most prominent type is the Generic Object Oriented Substation Event GOOSE. The other one is the so-called GSSE but is deprecated.

The GOOSE is defined in the IEC 61850-8-1 standard and is commonly used to communicate between servers, such as bay controllers and switchgear control units.

GOOSE does not use TCP/IP but instead utilizes multicast mechanist to be sent to all communication participants in the same LAN/VLAN. Its sending or publishing and its use or subscription are therefore completely separated. This separation also influences the configuration of GOOSE-related communication in the SCL.

Publishing: GOOSE Control Block (GSEControl)

The configuration of GOOSE publishers is done in the SCL element GSEControl and its referenced DataSet element. The reference to its DataSet is set through the attribute datSet in the GSEControl element.

NOTE: GSEControl must reside in the LN0 element, and both GSEControl and its referenced DataSet must have the same parent.

1. Create control block: Create the element GSEControl or import SCL with pre-existing GSEControl elements.
2. Create data set: Create element DataSet in the same parent as the GSEControl and add data FCDA to it.
3. Combine control block and data set: Set the datSet attribute within the GSEControl element.
