What Is Roundback?

The definition of the name is Fast Cut Back. It refers to severe faults such as tripping of important auxiliary equipment of the generator set or decommissioning of the turbine (sudden disconnection of the unit from the power grid: that is, the power supply load trips suddenly) or TB Trip. To meet the needs, FCB is required. There are two cases:

FCB

(Load switch back)

The power load of the unit suddenly trips. In order to maintain the unit to maintain the plant power operation, that is, the boiler is maintained at a minimum load without stopping the furnace.

The FCB makes the turbine RB or shut down. The steam generated by the boiler is output through the bypass system, and the boiler continues to maintain a minimum load, that is, the boiler is stopped without stopping. This is generally the case for FCB.
