Application manual

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.

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 UBasebase voltage setting (for each instance x).
GlobalBaseSel: Selects the global base value group used by the function to define
(IBase), (UBase) and (SBase).
