7.6.3.2.1 Handover UP Swap sequence
As explain above, the automatic priority swapping evaluates the load of the system and assigns the
most appropriate power band. The handover UP sequence describes the situation the gen-set with
lower nominal power is swapped by the gen-set with higher nominal power. The gen-set with lower
nominal capacity is stopped once the sequence is over. The stopped gen-set is in ready state and
keeps available in power management.

If the power band change delay Pwr management: #PwrBnChngDlUp is adjusted to that longer value
than total time requiring start of other gen-set, stabilization, synchronization, GCB closing and soft
loading, it postpones the soft unloading of the gen-set to be stopped. This delay is depicted by the
dashed orange line. Consequently, the handover up swap sequence is postponed by this delay.
