This standard defines a method for exchange of synchronized phasor measurement data between power system equipment. It specifies messaging including types, use, contents, and data formats for real-time communication between phasor measurement units (PMU), phasor data concentrators (PDC), and other applications. This revision includes i) communications between a single PMU and a PDC, ii) PDC functions dealing with multiple PMUs, and iii) onwards communications from the PDC.

The purpose for this standard is to facilitate data exchange among measurement, data collection, and application equipment. It provides a defined, open access method for all vendors to use to facilitate development and use of synchrophasors. It is a simple and direct method of data transmission and accretion within a phasor measurement system which may be used directly or with other communication protocols. This method was initially established by IEEE Std C37.118-2005, Standard for Synchrophasors for Power Systems, and subsequently by IEEE Std C37.118.2-2011.

Revision Standard – Active – Draft. A method for real-time exchange of synchronized phasor measurement data between power system equipment is defined. This standard specifies messaging that can be used with any suitable communication protocol for real-time communication between phasor measurement units (PMU), phasor data concentrators (PDC), and other applications. It defines message types, contents, and use. Data types and formats are specified. A typical measurement system is described. Communication options and requirements are described. Cybersecurity is discussed, and while its importance is acknowledged in the overall system, it is beyond the scope of this standard.
