IEC 61850 COMMUNICATIONS
Configurable GOOSE reception
120
Retransmission Profile
Range: None, Aggressive, Standard, Relaxed
Default: Standard
Plus
The D90 supports four retransmission schemes: aggressive, standard, relaxed, and
none.
The following retransmission times are specified under these profiles.
– Aggressive — Select for trip schemes — 4, 8, 16, 32, and 64 ms
– Standard — Select for remedial action schemes — 16, 32, 64, 128, and 256 ms
(default)
– Relaxed — Select for analog data sets — 100, 200, 400, 800, and 1000 ms
– None — Select for schemes that incorporate a separate confirmation scheme —
no retransmission
These selections are available on a transmit dataset-by-dataset basis. For GSSE and
fixed GOOSE, the profile is fixed at "Aggressive" and there is no associated setting.
Dataset Item 1, Dataset Item 2, Dataset Item 3,..., Dataset Item 64
Range: all valid MMS data item references for transmitted data
Default: 0
These settings are used to select an MMS data item for each configurable GOOSE
dataset item.
To create a configurable GOOSE dataset that contains an IEC 61850 Single Point Status
indication and its associated quality flags, the following dataset items can be selected:
"GGIO1.ST.Ind1.stVal" and "GGIO1.ST.Ind1.q." The D90
containing these two data items. The status value for GGIO1.ST.Ind1.stVal is determined
by the operand assigned to GGIO1 indication 1. Changes to this operand result in the
transmission of GOOSE messages containing the defined dataset.
