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

Global base values GBASVAL

Identification

Function description
Global base values

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.
This is an advantage since all applicable functions in the IED use a single source of
base values. This facilitates consistency throughout the IED and also facilitates a
single point for updating values when necessary.
Each applicable function in the IED has a parameter, GlobalBaseSel, defining one
out of the twelve sets of GBASVAL functions.
Setting guidelines
UBase: Phase-to-phase voltage value to be used as a base value for applicable
functions throughout the IED.
