REC650 is used for the control, protection and monitoring of
different types of bays in power networks. The IED is
especially suitable for applications in control systems with
distributed control IEDs in all bays with high demands on
reliability. It is suitable for the control of all apparatuses in the
following switchgear arrangements:
• Single busbar, with a single circuit breaker
• Double busbar, with a single circuit breaker
The control is performed from remote (SCADA/Station)
through various communication protocols or from the local
HMI.
Different control configurations can be used, and one control
IED per bay is recommended. Interlocking modules are
available for common types of switchgear arrangements. The
control is based on the select before execute principle to give
highest possible security. A synchronism control function is
available to interlock breaker closing. A synchronizing
function where breaker closes at the right instance in
asynchronous networks is also provided.
Disturbance recording is available to allow independent post-
fault analysis after primary disturbances.
One pre-configured package has been defined for the
following application:
• Single breaker, double busbar (A02)
The package is configured and ready for direct use. Analog
and control circuits have been pre-defined and other signals
need to be applied as required for each application. The pre-
configured IED can be changed and adapted to suit specific
applications with the application configuration tool.
The IED can be used in applications with the
IEC 61850-9-2LE process bus with up to four Merging Units
(MU). Each MU has eight analog channels, four current and
four voltages. Conventional input transformer module and
Merging Unit channels can be mixed freely in your application.
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 and IOM) 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.
The 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.
