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.
