15.1.4 Setting guidelines
M12550-3 v14
The setting parameters for the Synchronizing, synchronism check and ener
gizing check
function SESRSYN (25) are set via the local HMI (LHMI) or PCM600.
This setting guidelines describes the settings of the SESRSYN (25) function via the
LHMI.
Common base IED value for primary voltage ( VBase ) is set in a Global base value
function, GBASVAL, found under Main menu//Configuration/Power system/
GlobalBaseValue/GBASVAL_X/VBase. The SESRSYN (25) 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 (25) 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 Enabled or Disabled. The setting Disabled
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:
