ABB Bailey TAS01 Automatic Synchronizer Control Module

Description

The ABB TAS01 is a precision-engineered automatic synchronization module designed for the Bailey INFI 90 and Symphony Plus control systems. Its primary function is to manage the safe and efficient paralleling of AC generators with the main power grid or other live bus systems. The module continuously monitors the voltage, frequency, and phase angle of both the incoming source and the energized bus, calculating the optimal moment to issue a circuit breaker closure command. By automating the synchronization process, the TAS01 prevents significant mechanical stress and electrical surges associated with out-of-phase closing, ensuring the stability of power generation assets. It is widely utilized in hydroelectric, steam turbine, and industrial co-generation facilities where reliable grid synchronization is a critical operational requirement.
