Internally connected
A network where Bus1 is connected to Bus3, Bus2 is connected to Bus4 and CB1 is
closed is seen as an internally connected network by CB2.
Description
Any of the selected sources are ready for
matching.
Any source is selected for matching and the
governor and AVR of all the participating sources
are not in droop mode and non-participating
sources are not in "Fixed MW" and "Fixed MVAr"
mode.
The governor and Automatic Voltage Regulator
(AVR) modes corresponding to each source are
received via the corresponding input signal
SRC1_ASC_DAT...SRC8_ASC_DAT. If modes are
different, then mode change request is sent to the
sources via the corresponding output signal
ASC_SRC1_DAT...ASC_SRC8_DAT.
Any source is selected for matching, and its
governor and AVR are in droop mode and non-
participating sources are in "Fixed MW" and "Fixed
MVAr" mode.
All the selected sources are issued the permission
for matching.
Matching is complete according to the NSCB
under synchronization.
Matching is not done within the set
time .
The network is internally connected and setting
Synchrocheck mode in ASNSCSYN is
"Synchronous".
The network is internally connected and setting
Synchrocheck mode in ASNSCSYN is
"Asynchronous".
The network is externally connected.
The network is internally asynchronous and
Synchrocheck mode in ASNSCSYN is
setting
"Synchronous".
