Figure 4. Tap changer control and power transformer thermal overload protection using REU615 with the
standard configuration B. The tap changer position information is received as a mA-signal from the tap
changer operation mechanism. The position value is sent to the transformer differential protection
function of the RET615 IED using GOOSE messaging. Further, the analog GOOSE messaging enables
the tap changer control of the two parallel running power transformers. The RTD inputs complement the
thermal overload protection by measuring the oil and ambient temperature of the power transformer.

5. Supported ABB solutions

ABB's 615 series protection and control IEDs
together with the Grid Automation controller
COM600 constitute a genuine IEC 61850 solution
for reliable power distribution in utility and
industrial power systems. To facilitate and
streamline the system engineering ABB's IEDs are
supplied with Connectivity Packages containing a
compilation of software and IED-specific
information including single-line diagram
templates, a full IED data model including event
and parameter lists. By utilizing the Connectivity
Packages the IEDs can be readily configured via
the PCM600 Protection and Control IED Manager
and integrated with the Grid Automation controller
COM600 or the MicroSCADA Pro network control
and management system.
The 615 series IEDs offer native support for the
IEC 61850 standard also including binary and
analog horizontal GOOSE messaging. Compared
with traditional hard-wired inter-device signaling,
10
peer-to-peer communication over a switched
Ethernet LAN offers an advanced and versatile
platform for power system protection. Fast
software-based communication, continuous
supervision of the integrity of the protection and
communication system, and inherent flexibility for
reconfiguration and upgrades are among the
distinctive features of the protection system
approach enabled by the full implementation of
the IEC 61850 substation automation standard.
At the substation level COM600 uses the data
content of the bay level IEDs to offer enhanced
substation level functionality. COM600 features a
web-browser based HMI providing a
customizable graphical display for visualizing
single line mimic diagrams for switchgear bay
solutions. The SLD feature is especially useful
when 615 series IEDs without the optional single
line diagram feature are used. Further, the web
HMI of COM600 offers an overview of the whole
substation, including IED-specific single line
