1. 650 series overview
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 to use 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 settings 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
Breaker protection REQ650 provides a
standalone solution for applications, where
synchronism check 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 (A01A). 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 (A11A). 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 (B11A). 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 synchronism check 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.
