High-speed busbar protection system improves performance

ABB has introduced a new high-speed substation busbar protection system for utility
and industrial power systems.

The busbar protection application is based on the company’s novel REF615 feeder protection relay.

It supports the IEC 61850 standard “communication networks and systems in substations” and its GOOSE services.

This smart grid-enabled relay offers a platform to advance the performance, reliability and cost effectiveness of current power systems and beyond.

The new 615 series protection relays offer native support for the IEC 61850 substation
automation standard also including horizontal GOOSE (Generic Object Oriented Substation Event) messaging.

Compared with traditional hard-wired inter-relay signalling, relay-to-relay communication over a switched Ethernet LAN (Local Area Network) offers an advanced and versatile platform for protecting smart power systems.

Fast software-based configuration, 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 new protection system approach enabled by the full implementation of the IEC 61850 standard.
