ABB REG670 - Time Synchronization TIMESYNCHGEN

20.6 Time synchronization TIMESYNCHGEN
20.6.1 Functionality
The time synchronization function is used to select a common source of absolute time
for the synchronization of the IED when it is a part of a protection system. This makes
it possible to compare events and disturbance data between all IEDs within a station
automation system and in between sub-stations.
Micro SCADA OPC server should not be used as a time
synchronization source.
20.6.2 Settings
There are two groups of parameter settings related to time:
• System time
• Synchronization
The System time group relates to setting the on/off and start/end of the Daylight
Saving Time (DST) for the local time zone in relation to Coordinated Universal Time
(UTC). The Synchronization group relates to selecting the coarse and fine
synchronization sources. As well as defining the synchronization master and accuracy
levels specifically for IEC 61850-9-2.
All the settings and parameters related to time are available via Local HMI under
Main menu/Configuration/Time/System time and via PCM600 under IED
Configuration/Time.
