15.1.4 Setting guidelines
The setting parameters for the Synchronizing, synchrocheck and energizing check
function SESRSYN are set via the local HMI (LHMI) or PCM600.
This setting guidelines describes the settings of the SESRSYN function via the LHMI.
Common base IED value for primary voltage ( UBase ) is set in a Global base value
function, GBASVAL, found under
Main menu//Configuration/Power system/
GlobalBaseValue/GBASVAL_X/UBase . The SESRSYN function has one setting
for the bus reference voltage ( GblBaseSelBus ) and one setting for the line reference
voltage ( GblBaseSelLine ) which independently of each other can be set to select one
of the twelve GBASVAL functions used for reference of base values. This means that
the reference voltage of bus and line can be set to different values. The settings for the
SESRSYN function are found under
Main menu/Settings/IED Settings/Control/
Synchronizing(25,SC/VC)/SESRSYN(25,SC/VC):X has been divided into four
different setting groups: General, Synchronizing, Synchrocheck and
Energizingcheck.
General settings
Operation : The operation mode can be set On or Off . The setting Off disables the
whole function.
GblBaseSelBus and GblBaseSelLine
These configuration settings are used for selecting one of twelve GBASVAL
functions, which then is used as base value reference voltage, for bus and line
respectively.
SelPhaseBus1 and SelPhaseBus2
Configuration parameters for selecting the measuring phase of the voltage for busbar
1 and 2 respectively, which can be a single-phase (phase-neutral), two-phase (phase-
phase) or a positive sequence voltage.
SelPhaseLine1 and SelPhaseLine2
Configuration parameters for selecting the measuring phase of the voltage for line 1
and 2 respectively, which can be a single-phase (phase-neutral), two-phase (phase-
phase) or a positive sequence voltage.
CBConfig
This configuration setting is used to define type of voltage selection. Type of voltage
selection can be selected as:
