1. 650 series overview
P
rotection for a wide range of applications, control of switching
devices with interlocking, and monitoring can be provided in
one IED.
The 650 series IEDs provide both customized and configured
solutions. With the customized IEDs you have the freedom to
completely adapt the functionality according to your needs.
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:
• Customized versions providing the possibility to adapt the
functionality to the application needs for protection and
control in one IED.
• Configured versions solutions are completely ready to use
and 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 rule based parameter settings based on default
values and ABB's global base value concept. You only need
to set those parameters specific to your own installed and
activated application.
• GOOSE messaging for horizontal communication on
bumpless redundant station bus following IEC62439–3 ed2
PRP.
• 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.
• Role based access control with independent passwords and
FTPS encrypted communication. Managed authentication
and accounting of all user activities.
2. Application
REG650 is used for the protection and monitoring of generating
plants. The IED is especially suitable for applications in
distributed control systems with high demands on reliability. It is
intended mainly for small and medium size generation stations.
Apparatus control for up to 8 apparatuses with interlocking can
be included in one IED by function block engineering
REG670 may be used when more extensive protection systems
are required or in combination with REG650 to provide
redundant schemes.
A wide range of protection functions is available to achieve full
and reliable protection for different types of generating plants,
for example hydro power plants and thermal power plants. This
enables adaptation to the protection requirements of most
generating plants.
Protection functions are available for detecting and clearing
internal faults, such as generator stator short circuits and earth
faults, generator rotor earth faults, unit transformer short
circuits and earth faults and faults in the external power system,
fed from the generating plant.
Two packages have been defined for the following applications:
• Generator protection IED including generator differential
protection (B01)
• Generator-transformer unit protection IED including
transformer differential protection (B05)
In many generating plants, the protection system can be
designed with a combination of the two packages, that is, two
IEDs of either same type or different types, will give redundant
protection for a generating unit (generator and unit transformer)
depending on the requirements for the plant design.
The packages are configured and ready for use. Analogue
inputs and binary input/output circuits are pre-defined.
The configured IED can be changed and adapted with the
graphical configuration tool.
