Setting guidelines

The setting parameters for the Synchronizing, synchronism check and energizing 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.
The SESRSYN function has the following four configuration parameters, which on the
LHMI are found under Settings/General Settings/Control/Synchronizing(RSYN,25)/
SESRSYN:X.
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.
The same voltages must be used for both Bus and Line or, alternatively,
a compensation of angle difference can be set. See setting PhaseShift
below under General Settings.
The SESRSYN function has one setting for the bus reference voltage (UBaseBus) and
one setting for the line reference voltage (UBaseLine), which can be set as a reference
of base values independently of each other. This means that the reference voltage of
bus and line can be set to different values, which is necessary, for example, when
synchronizing via a transformer.
The settings for the SESRSYN function are found under Settings/Setting group N/
Control/Synchronizing(RSYN,25)/SESRSYN:X on the LHMI and are divided into
four different groups: General, Synchronizing, Synchrocheck and Energizingcheck.
General settings
Operation: The operation mode can be set Enabled or Disabled from PST. The setting
Disabled disables the whole SESRSYN function.
