C.4GENERIC SUBSTATION EVENT SERVICES: GSSE AND GOOSE
IEC 61850 specifies two types of peer-to-peer data transfer
services: Generic Substation State Events (GSSE) and
Generic Object Oriented Substation Events (GOOSE).
GSSE services are compatible with UCA 2.0 GOOSE. IEC
61850 GOOSE services provide virtual LAN (VLAN) sup-
port, Ethernet priority tagging, and Ethertype Application ID
configuration. The support for VLANs and priority tagging
allows for the optimization of Ethernet network traffic.
GOOSE messages can be given a higher priority than
standard Ethernet traffic, and they can be separated onto
specific VLANs. Because of the additional features of
GOOSE services versus GSSE services, it is recom-
mended that GOOSE be used wherever backwards com-
patibility with GSSE (or UCA 2.0 GOOSE) is not required.
Devices that transmit GSSE and/or GOOSE messages
also function as servers. Each GSSE publisher contains a
"GSSE control block" to configure and control the transmis-
IEC 61850 Generic Substation Status Event (GSSE) com-
munication is compatible with UCA GOOSE communica-
tion. GSSE messages contain a number of double point
status data items. These items are transmitted in two pre-
defined data structures named DNA and UserSt. Each
DNA and UserSt item is referred to as a 'bit pair'. GSSE
messages are transmitted in response to state changes in
any of the data points contained in the message. GSSE
messages always contain the same number of DNA and
UserSt bit pairs. Depending the on the configuration, only
some of these bit pairs may have values that are of interest
to receiving devices.
The D30 supports two types of IEC 61850 Generic Object
Oriented Substation Event (GOOSE) communication: fixed
GOOSE and configurable GOOSE. All GOOSE messages
contain IEC 61850 data collected into a dataset. It is this
dataset that is transferred using GOOSE message ser-
vices. The dataset transferred using the D30 fixed GOOSE
is the same data that is transferred using the GSSE fea-
ture; that is, the DNA and UserSt bit pairs. The FlexLogic™
operands that determine the state of the DNA and UserSt
bit pairs are configurable via settings, but the fixed GOOSE
dataset always contains the same DNA/UserSt data struc-
The configurable GOOSE feature allows for the configura-
tion of the datasets to be transmitted and/or received from
the D30. The D30 supports the configuration of a number
of transmission and reception datasets, allowing for the
optimization of data transfer between devices. The config-

sion. Each GOOSE publisher contains a "GOOSE control
block" to configure and control the transmission. The trans-
mission is also controlled via device settings. These set-
tings can be seen in the ICD and/or SCD files, or in the
device configuration software or files.
IEC 61850 recommends a default priority value of 4 for
GOOSE. Ethernet traffic that does not contain a priority tag
has a default priority of 1. More details are specified in IEC
61850 part 8-1.
IEC 61850 recommends that the Ethertype Application ID
number be configured according to the GOOSE source. In
the D30, the transmitted GOOSE Application ID number
must match the configured receive Application ID number
in the receiver. A common number may be used for all
GOOSE transmitters in a system. More details are speci-
fied in IEC 61850 part 8-1.

entered for the
this address will be used as the destination MAC address
for GSSE messages. If a valid multicast Ethernet MAC
address is not entered (for example, 00 00 00 00 00 00),
the D30 will use the source Ethernet MAC address as the
destination, with the multicast bit set.
ture. Upgrading from GSSE to GOOSE services is simply a
matter of enabling fixed GOOSE and disabling GSSE. The
remote inputs and outputs are configured in the same man-
ner for both GSSE and fixed GOOSE.
It is recommended that the fixed GOOSE be used for
implementations that require GOOSE data transfer
between UR-series IEDs. Configurable GOOSE may be
used for implementations that require GOOSE data trans-
fer between UR-series IEDs and devices from other manu-
facturers.
urable GOOSE feature is recommended for applications
that require GOOSE data transfer between UR-series IEDs
and devices from other manufacturers. Fixed GOOSE is
recommended for applications that require GOOSE data
transfer between UR-series IEDs.
