Summation block 3 phase 3PHSUM

22.6.1

Application

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.
22.6.2 Setting guidelines
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 VBasebase voltage setting (for each instance x).
GlobalBaseSel: Selects the global base value group used by the function to define (IBase), (VBase) and
(SBase).
