Application
The IEDs can be equipped with communication devices for line differential communication (not
applicable for RER670) and/or communication of binary signals between IEDs. The same
communication hardware is used for both purposes.
Sending of binary signals between two IEDs is used in teleprotection schemes and for direct
transfer trips. In addition to this, there are application possibilities, for example, blocking/
enabling functionality in the remote substation, changing setting group in the remote IED
depending on the switching situation in the local substation and so on.
If equipped with a 64kbit/s LDCM module, the IED can be configured to send either 192 binary
signals or 3 analog and 8 binary signals to a remote IED. If equipped with a 2Mbps LDCM module,
the IED can send 9 analog channels and 192 binary channels to a remote IED.
Link forwarding
If it is not possible to have a communication link between each station, the solution has been to
set the protection up in a slave-master-slave configuration. This means that in Figure 246, only
IED-B has access to all currents and, therefore, this is the only place where the differential current
is evaluated. If the evaluation results in a trip, the trip signal will be sent over the two
communication links.
