ABB
Voltage Protection and Control
REU615
Product version: 4.0

1. Description

The voltage protection and control IED, REU615
is available in two standard configurations,
denoted A and B. Configuration A is preadapted
for voltage and frequency-based protection
schemes in utility and industrial power systems
and distribution systems including networks with
distributed power generation. The B configuration
is designed for automatic voltage regulation of
power transformers equipped with an on-load tap-
changer. Both configurations also feature
additional CB control, measuring and supervising
functions. REU615 is a member of ABB's Relion
product family and part of its 615 protection and
control product series. The 615 series IEDs are
characterized by their compactness and
withdrawable–unit design.
Re-engineered from the ground up, the 615 series
has been designed to unleash the full potential of
the IEC 61850 standard for communication and
interoperability between substation automation
devices. Once the standard configuration IED has

been given the application-specific settings, it can
directly be put into service.
The 615 series IEDs support a range of
communication protocols including IEC 61850
with GOOSE messaging, IEC 60870-5-103,
®
Modbus and DNP3.

2. Standard configurations

REU615 is available in two standard
configurations. The standard signal configuration
can be altered by means of the graphical signal
®
matrix or the graphical application functionality of
the Protection and Control IED Manager PCM600.
Further, the application configuration functionality
of PCM600 supports the creation of multi-layer
logic functions using various logical elements,
including timers and flip-flops. By combining
protection functions with logic function blocks,
the IED configuration can be adapted to user-
specific application requirements.
