Application - ABB REL650 Product Manual

Line distance protection REL650 2.2
Product version: 2.2.1

1. Application

REL650 is used for the protection, control and monitoring of
overhead lines and cables in solidly or impedance earthed
networks. It is suitable for the protection of heavily loaded
lines and multi-terminal lines where the requirement for fast
one- and/or three-phase tripping is wanted. Backup
protection and apparatus control for 1 circuit breaker is
included.
The full scheme distance protection provides protection of
power lines with high sensitivity and low requirement on
remote end communication. The 6 zones have fully
independent measuring and setting ranges which gives high
flexibility for all types of lines. Load encroachment and
adaptive reach compensation are included.
The multi-shot autoreclose includes priority features for
double-breaker arrangements. It cooperates with the
synchrocheck function with high-speed or delayed reclosing.
Breaker failure, high set instantaneous phase and earth
overcurrent, four step directional or non-directional delayed
phase and earth overcurrent and two step under voltage
protection are included and configured as back-up
protection.
The impedance protection and the directional overcurrent
protection can communicate with a remote end in any
teleprotection communication scheme. The advanced logic
capability, where the user logic is prepared with a graphical
tool, allows special applications.
Disturbance recording and fault locator are available to allow
independent post-fault analysis after primary disturbances.
Two pre-configured packages have been defined for the
following applications:
• Single breaker, 1/3 phase tripping (A11)
• Single breaker, 1/3 phase tripping, isolated or high
impedance earthed systems (A12)

The packages are configured and ready for direct use. Analog
and control circuits have been predefined and other signals
need to be applied as required for each application. The pre-
configured IEDs 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 analogue 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.
