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
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/Ethernet
configuration/Access point/AP_X:
•
Operation: On
•
PTP: On
Two status monitoring signals can be:
•
SYNCH signal on the MUx function block indicates that protection functions are blocked
due to loss of internal time synchronization to the IED
•
MUSYNCH signal on the MUx function block monitors the synchronization flag
in the datastream and IED hardware time synchronization.
