If only two SESRSYN functions are provided in the same IED, the connections and settings are
according to the SESRSYN functions for WA1_QA1 and TIE_QA1.
12.1.4 Setting guidelines
M12550-3 v14
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.
