IEC 61850-9-3: Precision Time Protocol Profile for Power Utility Automation

IEC TC 57 has published the other day:

IEC/PAS 61850-9-3 (57/1551/PAS):
Communication Networks and Systems for Power Utility Automation –
Part 9-3: Precision Time Protocol Profile for Power Utility Automation

Voting terminates on 2015-05-01

The intent of this publication is to present a widely agreed technical solution for a precision time protocol (PTP) profile of IEC 61588:2009 applicable to power utility automation. There is urgent need in the power industry for a appropriate profile for power automation application to be defined in IEC 61588. This PAS (Public Available Specification) is intended to temporarily be used as a reference.

This allows to meet the highest synchronization classes of 108 IEC 61850-5 and IEC 61869-9.
