provide a breaker failure function independent from the protection IEDs, also for a
complete breaker-and-a-half diameter.
Disturbance recording and fault locator are available to allow independent post-fault
analysis after primary disturbances in case of a failure in the protection system.
Duplex communication channels for transfer of up to 192 intertrip and binary signals
are available on each remote-end data communication card (LDCM). Typical
applications are the communication between IEDs inside the station or with IEDs in a
remote station as remote I/O.
Logic is prepared with a graphical tool. The advanced logic capability allows special
applications such as automatic opening of disconnectors in multi-breaker
arrangements, closing of breaker rings, load transfer logics and so on. The graphical
configuration tool ensures simple and fast testing and commissioning.
Forcing of binary inputs and outputs is a convenient way to test wiring in substations
as well as testing configuration logic in the IEDs. Basically it means that all binary
inputs and outputs on the IED I/O modules (BOM, BIM, IOM & SOM) can be forced
to arbitrary values.
Central Account Management is an authentication infrastructure that offers a secure
solution for enforcing access control to IEDs and other systems within a substation.
This incorporates management of user accounts, roles and certificates and the
distribution of such, a procedure completely transparent to the user.
Flexible Product Naming allows the customer to use an IED-vendor independent IEC
61850 model of the IED. This customer model will be used as the IEC 61850 data
model, but all other aspects of the IED will remain unchanged (e.g., names on the local
HMI and names in the tools). This offers significant flexibility to adapt the IED to the
customers' system and standard solution.
The following tables list all the functions available in the IED. Those
functions that are not exposed to the user or do not need to be
configured are not described in this manual.
