Release of new functionality for SSC600 – centralized protection and control for distribution substations

2020-04-08 Release announcement

We are pleased to announce the release of new functionality for ABB Ability™ smart substation control and protection for electrical systems SSC600, which centralizes all protection and control functionality in one device on substation level for station-wide visibility, minimal engineering, and easy and cost-efficient process management. Combining SSC600 with merging units creates a unique, IEC 61850-compliant, centralized protection and control solution.

The modular software and the continuous access to new software developments allow easy customization and adaptation to changing protection requirements for the lifetime of the digital substation. The advantage of only having to modify one device instead of all bay-level protection and control devices makes upgrading the entire substation system easier than ever.

A secure and reliable busbar protection is key to avoiding unnecessary disconnection of numerous feeders, which might otherwise cause a power outage for a large number of utility customers or production downtime in industry. The busbar protection also needs to be fast enough as uncleared faults generate high fault currents with thermal effects and dynamic forces as a result.

SSC600 therefore introduces an advanced, low impedance-based, high-speed busbar differential protection for detecting faults within the distribution substation and suitable for a variety of switchgear. Depending on the substation configuration, the busbar differential protection consists of either one or two zones and is suitable for both single and double-busbar configurations.With SSC600 now also covering busbar differential protection, there is no longer a need for dedicated, bay-specific busbar protection relays. Instead, SSC600 offers protection and control for the entire busbar and its up to 20 bays – by simply adding software.

What’s new?

  • Low impedance-based busbar differential protection (BBPBDF/87B), consisting of one or two zones depending on the substation configuration (single busbar, double busbar, one or two sections). Other related functionality is:
    • Separated check zone
    • Integrated sensitive earth-fault protection
    • Through-fault detection
    • Open CT detection
    • Separated zone selection for easy configuration
  • Voltage switch (VMSWI) for switching between four different voltage groups
  • Current switch (CMSWI) for switching between four different current groups
  • Current sum (CMSUM) – a phase-by-phase specific summing function for two current triplets
  • Role-based access control enabling customized roles with modifiable rights and unique user accounts
  • Centralized activity logging with syslog support
  • Various engineering enhancements including:
    • Configuration migration from previous SSC600 versions
    • Graphical GOOSE engineering
    • Graphical setting for protection coordination
