20.3.4.2 Setting examples for IEC/UCA 61850-9-2LE and time synchronization
The IED and the Merging Units (MU) should use the same time reference especially if analog data
is used from several sources, for example from an internal TRM and an MU, or if several physical
MUs are used. Having the same time reference is important to correlate data so that channels
from different sources refer to the correct phase angle.
When only one MU is used as an analog source, it is theoretically possible to do without time
synchronization. However, this would mean that timestamps for analog and binary data/events
become uncorrelated. If the IED has no time synchronization source configured, then the binary
data/events will be synchronized with the merging unit. However, the global/complete time might
not be correct. Disturbance recordings then appear incorrect since analog data is timestamped by
MU, and binary events use the internal IED time. It is thus recommended to use time
synchronization also when analog data emanate from only one MU.
An external time source can be used to synchronize both the IED and the MU. It is also possible to
use the MU as a clock master to synchronize the IED from the MU. When using an external clock, it
is possible to set the IED to be synchronized via PPS,IRIG-B or PTP. It is also possible to use an
internal GPS receiver in the IED (if the external clock is using GPS).
