1. 650 series overview GUID-420ACE74-2F34-4991-8DA3-967843F6BFFF v1
The 650 series IEDs provide optimum 'off-the-shelf',
ready-to-use solutions. It is configured with complete
protection functionality and default parameters to meet
the needs of a wide range of applications for generation
transmission and sub-transmission grids.
The 650 series IEDs include:
• Complete ready-made solutions optimized for a wide
range of applications for generation, transmission and
sub-transmission grids.
• Support for user-defined names in the local language
for signal and function engineering.
• Minimized parameter setting based on default values
and ABB's new global base value concept. You only
need to set those parameters specific to your own
application, such as the line data.
• GOOSE messaging for horizontal communication.
• Extended HMI functionality with 15 dynamic three-
color-indication LEDs per page, on up to three pages,
and configurable push-button shortcuts for different
actions.
• Programmable LED text-based labels.
• Settable 1A/5A -rated current inputs.
2. Application GUID-3DFF543C-4C48-48A0-8B2C-D0D4B9E5FDA4 v1
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 stand alone product. This IED
also enables well-structured and reliable protection and
control systems especially in systems where complete
bay control functionality including interlocking is not
required.
REQ650 provides backup to the main protection with
redundant protection and control functions.
Three pre-configured packages have been defined for
following applications:
• Backup protection functions in a breaker bay giving
three-phase trip (A01). The connection of the bay is to
a single or double busbar section.
• A breaker bay connecting a transmission line, with
back-up protection functions enabling single phase
trip (A11). The connection of the bay is only to a single
busbar section.
• A breaker bay connecting a transmission line, with
back-up protection functions enabling single phase
trip (B11). The connection of the bay can be made to
the double busbar sections.
The backup protection is mainly based on current and
voltage based functions. In line protection applications,
autoreclosing with or without synchrocheck is available.
The package is delivered pre-configured and ready for
use in the power system. Analogue inputs and binary
inputs/outputs circuits are pre-defined.
The pre-configured IED can be modified and adapted to
suit specific applications with the graphical
configuration tool, using the glue logic and adjusting
the parameter settings.
