ABB Relion® Protection and Control REX640 Supported ABB solutions

Supported ABB solutions

The REX640 protection relay together with the Substation

Management Unit COM600S constitutes a genuine IEC 61850

solution for reliable power distribution in utility and industrial

power systems. To facilitate the system engineering, ABB's

relays are supplied with connectivity packages. The

connectivity packages include a compilation of software and

relay-specific information, including single-line diagram

templates and a full relay data model. The data model includes

event and parameter lists. With the connectivity packages, the

relays can be readily configured using PCM600 and integrated

with COM600S or the network control and management

system MicroSCADA Pro.

REX640 offers native support for IEC 61850 Edition 2 including

binary and analog horizontal GOOSE messaging. In addition, a

process bus enabling sending and receiving of sampled values

of analog currents and voltages is supported.

Unlike the traditional hardwired, inter-device signaling, peer-to

peer communication over a switched Ethernet LAN offers an

advanced and versatile platform for power system protection.

Among the distinctive features of the protection system

approach, enabled by the full implementation of the IEC 61850

substation automation standard, are fast communication

capability, continuous supervision of the protection and

communication system's integrity, and flexible reconfiguration

and upgrades. This protection relay series is able to optimally

use the interoperability provided by the IEC 61850 Edition 2

features.

At substation level, COM600S uses the data content of the bay

level devices to enhance the substation level functionality.

COM600S features a Web browser-based HMI, which provides

a customizable graphical display for visualizing single-line

mimic diagrams for switchgear bay solutions. The Web HMI of

COM600S also provides an overview of the whole substation,

including relay-specific single-line diagrams, which makes

information easily accessible. Substation devices and

processes can also be remotely accessed through the Web

HMI, which improves personnel safety.

In addition, COM600S can be used as a local data warehouse

for the substation's technical documentation and for the

network data collected by the devices. The collected network

data facilitates extensive reporting and analyzing of network

fault situations by using the data historian and event handling

features of COM600S. The historical data can be used for

accurate monitoring of process and equipment performance,

using calculations based on both real-time and historical

values. A better understanding of the process dynamics is

achieved by combining time-based process measurements

with production and maintenance events.

COM600S can also function as a gateway and provide

seamless connectivity between the substation devices and

network-level control and management systems, such as

MicroSCADA Pro and System 800xA.

The GOOSE Analyzer interface in COM600S enables the

monitoring and the analysis of the horizontal IEC 61850

application during commissioning and operation at station

level. It logs all GOOSE events during substation operation to

enable improved system supervision.
