This document is a draft of a proposed IEC/IEEE Standard. As such, this document is subject to change. USE AT YOUR OWN RISK! Because this is a draft, this document must not be utlized for any conformance/compliance purposes.This part of the 60255 International Standard is for synchronized phasor measurement
systems in power systems. It defines a synchronized phasor (synchrophasor), frequency, and
rate of change of frequency measurements. It describes time tag and synchronization
requirements for measurement of all three of these quantities. It specifies methods for
evaluating these measurements and requirements for compliance with the standard under
both static and dynamic conditions. It defines a phasor measurement unit (PMU), which can
be a stand-alone physical unit or a functional unit within another physical unit. This document
does not specify hardware, software or a method for computing phasors, frequency, or rate of
change of frequency.
