ABB REB611 Busbar and Multipurpose Differential Protection Supported ABB solutions

Supported ABB solutions

The 611 series protection relays together with the Substation

Management Unit COM600S constitute 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 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.

The 611 series relays offer native support for the IEC 61850

standard, including limited binary GOOSE messaging.

Compared to traditional hard-wired, inter-device signaling,

peer-to-peer communication over a switched Ethernet LAN

offers an advanced and versatile platform for power system

protection. The implementation of the IEC 61850 substation

automation standard enables access to distinctive features

including fast software-based communication, continuous

supervision of the protection and communication system's

integrity, and inherent flexibility for reconfiguration and upgrades.

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

level devices to enhance 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.
