CONFIGURABLE GOOSE 1(8)
The configurable GOOSE settings allow the L90 to be configured to transmit a number of different datasets within IEC
61850 GOOSE messages. Up to eight different configurable datasets can be configured and transmitted. This is useful for
intercommunication between L90 IEDs and devices from other manufacturers that support IEC 61850.
The configurable GOOSE feature allows for the configuration of the datasets to be transmitted or received from the L90.
The L90 supports the configuration of eight (8) transmission and reception datasets, allowing for the optimization of data
transfer between devices.
Items programmed for dataset 1 and 2 will have changes in their status transmitted as soon as the change is detected.
Datasets 1 and 2 should be used for high-speed transmission of data that is required for applications such as transfer trip-
ping, blocking, and breaker fail initiate. At least one digital status value needs to be configured in the required dataset to
enable transmission of configured data. Configuring analog data only to dataset 1 or 2 will not activate transmission.
Items programmed for datasets 3 through 8 will have changes in their status transmitted at a maximum rate of every
100 ms. Datasets 3 through 8 will regularly analyze each data item configured within them every 100 ms to identify if any
changes have been made. If any changes in the data items are detected, these changes will be transmitted through a
GOOSE message. If there are no changes detected during this 100 ms period, no GOOSE message will be sent.
For all datasets 1 through 8, the integrity GOOSE message will still continue to be sent at the pre-configured rate even if no
changes in the data items are detected.
The GOOSE functionality was enhanced to prevent the relay from flooding a communications network with GOOSE mes-
sages due to an oscillation being created that is triggering a message.
The L90 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be
caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station
components. If erroneously oscillation is detected, the L90 will stop sending GOOSE messages from the dataset for a min-
imum period of one second. Should the oscillation persist after the one second time-out period, the L90 will continue to
block transmission of the dataset. The L90 will assert the

self-test error mes-
sage on the front panel display, where
XXX
denotes the data item detected as oscillating.
For versions 5.70 and higher, the L90 supports four retransmission schemes: aggressive, medium, relaxed, and heartbeat.
The aggressive scheme is only supported in fast type 1A GOOSE messages (GOOSEOut 1 and GOOSEOut 2). For slow
GOOSE messages (GOOSEOut 3 to GOOSEOut 8) the aggressive scheme is the same as the medium scheme.
