Summation block 3 phase 3PHSUM

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) .
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).

Application
Global base values function (GBASVAL) is used to provide global values, common for
all applicable functions within the IED. One set of global values consists of values for
current, voltage and apparent power and it is possible to have twelve different sets.
