Standard profile for use of IEEE Std 1588-2008 Precision Time Protocol (PTP) in power system applications: IEEE PES PSRC Working Group H7/Sub C7 members and guests

This paper provides a summary of the IEEE C37.238-2011 standard, which specifies a subset of PTP parameters and options to provide global time availability, device interoperability, and failure management. This set of PTP parameters and options allows IEEE 1588-based time synchronization to be used in mission critical power system protection, control, automation, and data communication applications utilizing Ethernet communications architecture.
