22.6.1
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.
22.6.2
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
UBase
base voltage setting (for each instance x).
GlobalBaseSel
: Selects the global base value group used by the function to define
(
IBase
), (
UBase
) and (
SBase
).
