Setting example with PTP synchronization
Settings on the local HMI under
Main menu/Configuration/Time/
Synchronization/TIMESYNCHGEN:1/IEC61850-9-2
:
•
HwSyncSrc
: is not used as the SW-time and HW-time are connected with each
other due to PTP
•
SyncLostMode
: set to
Block
to block protection functions if time
synchronization is lost or set to
BlockOnLostUTC
if the protection functions
are to be blocked when global common synchronization is lost
•
SyncAccLevel
: can be set to
1μs
since this corresponds to a maximum phase
angle error of 0.018 degrees at 50Hz
Settings on the local HMI under
Main menu/Configuration/Communication/
