Setting guidelines

Remember always that there are two possible ways to place the IED in the
state. If, the IED is set to normal operation (
being in the test mode, the input signal IED_TEST on the TESTMODE function block is
activated in the configuration.
Forcing of binary input and output signals is only possible when the IED is in IED test mode.

Time synchronization TIMESYNCHGEN

9.9.1

Application

Use time synchronization to achieve a common time base for the IEDs in a protection and
control system. This makes it possible to compare events and disturbance data between all
IEDs in the system.
Time-tagging of internal events and disturbances are an excellent help when evaluating faults.
Without time synchronization, only the events within one IED can be compared with each
other. With time synchronization, events and disturbances within the whole network, can be
compared and evaluated.
In the IED, the internal time can be synchronized from BIN (Binary Minute Pulse), SNTP, and
IEEE 1588 (PTP) source.
The selection of the time source is done via the corresponding setting.
If PTP is activated, the device with the best accuracy within the synchronizing group will be
selected as the source. For more information about PTP, see the Technical 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.
9.9.2 Setting guidelines
All the parameters related to time are divided into two categories: System time and
Synchronization.

System time

The time is set with years, month, day, hour, minute, second and millisecond.
