20.5.2
Application
M15288-3 v6
The rated system frequency and phase rotation direction are set under Main menu/
Configuration/ Power system/ Primary Values in the local HMI and PCM600 parameter
setting tree.
20.5.3
Setting guidelines
M15292-3 v2
Set the system rated frequency. Refer to section
"Signal matrix for analog inputs SMAI"
description on frequency tracking.

Summation block 3 phase 3PHSUM
SEMOD55968-1 v2
20.6.1
Application
SEMOD56004-4 v3
The analog summation block 3PHSUM function block is used in order to get the sum of two
sets of 3 phase analog signals (of the same type) for those IED functions that might need it.
20.6.2
Setting guidelines
SEMOD56006-4 v7
The summation block receives the three-phase signals from SMAI blocks. The summation block
has several settings.
SummationType: Summation type (Group 1 + Group 2, Group 1 - Group 2, Group 2 - Group 1 or –
(Group 1 + Group 2)).
DFTReference: The reference DFT block (InternalDFT Ref,DFTRefGrp1 or External DFT ref) .
DFTRefGrp1: This setting means use own internal adaptive DFT reference ( this setting makes
the
SUM3PH self DFT adaptive, that is, it will use the measured frequency for the summation
signal to adapt DFT).
InternalDFTRef: Gives fixed window DFT (to nominal system frequency).
ExternalDFTRef: This setting means that the DFT samples-per-cycle (adaptive DFT) will be
controlled by SMAI1 SPFCOUT.
FreqMeasMinVal: The minimum value of the voltage for which the frequency is calculated,
expressed as percent of
UBasebase voltage setting (for each instance x).
GlobalBaseSel: Selects the global base value group used by the function to define (IBase),
(
UBase) and (SBase).
