24.6 Summation block 3 phase 3PHSUM
SEMOD55968-1 v2
24.6.1 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.
24.6.2 Setting guidelines
SEMOD56006-4 v6
The summation block receives the three-phase signals from SMAI blocks. The
summation block has several settings.
SummationT
ype: 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) .
FreqMeasMinVal: The minimum value of the voltage for which the frequency is
calculated, expressed as percent of VBasebase voltage setting (for each instance x).
GlobalBaseSel: Selects the global base value group used by the function to define
(IBase), (VBase) and (SBase).
