Settings for 61850 communications
10.3.4
Setting time for re-sending GOOSE packet
(i)
The user can configure the maximum duration time for re-sending GOOSE packet. Set the
time in seconds using setting [GOINT].
The setting values have been included in the CID file of the IEC 61850. The IED uses the
information of the CID file when the IED starts up. As the setting values have been included
in the CID file, the user can modify this setting value with the GR-TIEMS. The user is required
to write both of the setting values and the IEC61850-CID file into the IED.
Setting for 61850 authentication
(ii)
When the IED is to be authenticated for starting the IEC 61850 communications, the user
should set scheme switch [850AUT] On.
Blocking 61850 communication
(iii)
If the user does not want the IED to start the IEC 61850 communications, the user should set
scheme switch [850BLK] On.
Setting 'keep-alive' time for TCP
(iv)
When applying IEC 61850 communications with TCP/IP, the user should set a time for the
'keep-alive' signal. The user should set the time in seconds using the setting [850KEEPALIVE].
Setting 'CommTerm'
(v)
If the user wishes to receive a 'CommTerm' signal carrying an actual operation time from a
device outside the IED, the user should set scheme switch [TCMD] On. Note that the
'CommTerm' signal† will not conform to the IEC 61850 standard when the user turns on this
function. That is, this function can be availed on the server communication provided by
TOSHIBA.
†Note: For example, Figure 10.3-27 shows the signal flow between a substation computer
(SC), an IED and a target device (e.g. CB). If the requirement is to close the CB on
request of the SC, the SC will send the operation command "Operate" to the IED;
the time information (T) is also sent along with the operation command. When
receiving the operation command and observing that the CB has closed, the IED
will send a response signal "CommTerm" to the SC along with the time
information. However, this time information is not the actual operation time of the
CB, but the same time information originally sent with the operation command.
The IEC 61850 standard defines this rule; hence, general operations in the IEC
61850 standard are subject to this rule. However, the server communication
