Figure 215: 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/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
smpSynch
in the datastream and IED hardware time synchronization.
