1. Application GUID-3F024D79-D031-42DC-B0BC-1F3757B8D3E0 v3
Breaker protection REQ650 provides a standalone solution
for applications where synchrocheck controlled closing of the
circuit breaker is required, but the integration of the automatic
reclosing function into the main line protection IED is not
preferred or suitable. The advanced automatic reclosing,
synchronizing, synchrocheck and energizing check functions
of REQ650 provides an optimized standalone product.
REQ650 provides backup to the main protection with
redundant protection and control functions.
One pre-configured package has been defined for the
following application:
• A breaker bay connecting a transmission line to a
busbar, with back-up protection functions enabling
single or three phase trip (B11)
The backup protection is based on basic overcurrent and
voltage based functions. In line protection applications,
autoreclosing with or without synchrocheck is available.
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 graphical configuration tool.
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 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
