Function description
Primary system values
22.5.2 Application
The rated system frequency and phase rotation direction are set under Main menu/
Configuration/ Power system/ Primary Values in the local HMI and PCM600 parameter setting
tree.
22.5.3 Setting guidelines
Set the system rated frequency. Refer to section
description on frequency tracking.
22.6 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
GlobalBaseSel : Selects the global base value group used by the function to define ( IBase ), ( VBase )
SBase ).
