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 part IEC 61850-8-1. It is often applied to communicate between servers such as bay controller and switch gear control unit.
GOOSE does not use TCP/IP but uses multicast mechanist instead to be send to all communication participants in the same LAN/VLAN. Its sending or publishing and its use or subscription are therefore completely separated. Tha has its effect also on 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 theLN0
element andGSEControl
and its referencedDataSet
must have the same parent
- create control block: Create the element
GSEControl
or import SCL with pre-existingGSEControl
elements - create data set: Create element
DataSet
in the same parent as theGSEControl
and add dataFCDA
to it - combine control block and data set: Set the
datSet
attribute within theGSEControl
element
