ABB Symphony Plus S+ Turbine: Auto Synchronizer Module AS800
Highlights
The Auto Synchronizer AS800 provides automatic breaker
closure during generator to line synchronization or during peer
to peer bus synchronization in switchyard applications. The
AS800 is also capable of detecting a dead bus to initiate safe
breaker closure from a live bus to a de-energized bus. The
AS800 may be installed in centralized or remote locations. The
AS800 integrates into DCS systems or operates standalone.
Communication to the module is accomplished through the
on-board Profibus interface for DCS operation or through a
serial interface for standalone configuration. Monitoring and
configuration are available via either of these communication
ports.
