Smart substation control and protection SSC600

Centralized protection and control for distribution substations

ABB Ability™ Smart Substation Control and Protection for electrical systems SSC600 centralizes all protection and control functionality into one single device on distribution substation level for minimal engineering, station-wide visibility and optimal process management. Combining SSC600 with merging units creates an IEC 61850-compliant centralized protection and control solution. The modular software can be flexibly modified for the entire lifetime of the digital substation and allows SSC600 to change with the evolving grid. SSC600 builds on ABB’s solid and proven technological foundation manifested in the renowned Relion® protection and control family of relays.

SSC600 functionality is also available as a virtualized product, SSC600 SW, which enables customers to use the hardware of their choice and gain access to the same proven protection and control functionality as with the turnkey solution.
