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.
The IED can be used in applications with the IEC/UCA 61850-9-2LE process bus
with up to eight Merging Units (MU). Each MU has eight analogue channels, four
current and four voltages. Conventional input transformer module and Merging
Unit channels can be mixed freely in your application.
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.
