PSS
BESTCOMSPlus Navigation Path: Metering Explorer, PSS (Power System Stabilizer)
Values metered by the power system stabilizer function display positive sequence voltage and current,
negative sequence voltage and current, terminal frequency deviation, compensated frequency deviation,
and the per-unit PSS output level. The PSS function on/off status is also reported. Primary- and per-unit
values are available. Figure 11-7 illustrates the PSS primary-values metering screen.

Synchronization
BESTCOMSPlus Navigation Path: Metering Explorer, Synchronization
Metered generator-to-bus synchronization parameters include the slip frequency, slip angle, and voltage
difference. Primary- and per-unit values are available. Figure 11-8 illustrates the synchronization primary-
values metering screen.

Auxiliary Control Input
BESTCOMSPlus Navigation Path: Metering Explorer, Aux Input
The control signal applied at the DECS-150 auxiliary control input is indicated on the Aux Input metering
screen (Figure 11-9). As configured in BESTCOMSPlus
®
, a dc voltage or dc current signal may be
applied.
