Figure 10: IEC 61850: Principle operation of GOOSE messages
The Generic Object Oriented Substation Event (GOOSE) class model is used to
distribute input and output data values between IEDs on bay level (in horizontal
direction) through the use of multicast services. GOOSE messages enable fast
transmission from a publisher to one or several subscribers (receivers).
The GOOSE service model of IEC 61850-7-2 provides the possibility for fast and
reliable system-wide distribution of input and output data values. This
implementation uses a specific scheme of re-transmission to achieve the
appropriate level of reliability. When a GOOSE server generates a
SendGOOSEMessage request, the current data set values are encoded in a GOOSE
message and transmitted on the multicast association. The event that causes the
