No time synchronization
This example is not valid when GPS time is used for differential
protection, when PTP is enabled or when the PMU report is used.

Setting example without time synchronization
It is also possible to use IEC/UCA 61850-9-2LE communication without time
synchronization.
Settings on the local HMI under
Main menu/Configuration/Time/
Synchronization/TIMESYNCHGEN:1/IEC61850-9-2
:
•
HwSyncSrc
: set to
Off
•
SyncLostMode
: set to
No block
to indicate that protection functions are not
blocked
•
SyncAccLevel
: set to
unspecified
Two status monitoring signals with no time synchronization:
•
SYNCH signal on the MUx function block indicates that protection functions
are blocked due to loss of internal time synchronization to the IED. Since
SyncLostMode
is set to
No block
, this signal is not set.
•
MUSYNCH signal on the MUx function block is set if the datastream
indicates time synchronization loss. However, protection functions are not
blocked.
To get higher availability in protection functions, it is possible to avoid blocking
during time synchronization loss if there is a single source of analog data. This
means that if there is only one physical MU and no TRM, parameter
SyncLostMode
is set to
No block
but parameter
HwSyncSrc
is still set to
PPS
. This maintains
