ABB REG670 Applications Manual

IEEE 1588 (PTP)
PTP according to IEEE 1588-2008 and specifically its profile IEC/IEEE 61850-9-3
for power utility automation is a synchronization method that can be used to maintain
a common time within a station. This time can be synchronized to the global time
using, for instance, a GPS receiver. If PTP is enabled on the IEDs and the switches that
connect the station are compatible with IEEE 1588, the station will become
synchronized to one common time with an accuracy of under 1us. Using an IED as a
boundary clock between several networks will keep 1us accuracy on three levels or
when using an HSR, 15 IEDs can be connected in a ring without losing a single
microsecond in accuracy.
23.13.2 Setting guidelines
All the parameters related to time are divided into two categories: System time and
Synchronization.
23.13.2.1 System time
The time is set with years, month, day, hour, minute, second and millisecond.
23.13.2.2 Synchronization
The setting parameters for the real-time clock with external time synchronization are
set via local HMI or PCM600. The path for Time Synchronization parameters on local
HMI is Main menu/Configuration/Time/Synchronization. The parameters are
categorized as Time Synchronization (TIMESYNCHGEN) and IRIG-B settings
(IRIG-B:1) in case that IRIG-B is used as the external time synchronization source.
TimeSynch
When the source of the time synchronization is selected on the local HMI, the
parameter is called TimeSynch. The time synchronization source can also be set from
PCM600. The setting alternatives are:
FineSyncSource which can have the following values:
• Off
• SPA
• LON
• BIN (Binary Minute Pulse)
• GPS
• GPS+SPA
• GPS+LON
• GPS+BIN
• SNTP
• GPS+SNTP
• IRIG-B
• GPS+IRIG-B
• PPS
