1 Scope

This document defines the measurements of synchrophasor, frequency, and rate of change of frequency, specifies the time scale and synchronization requirements for the three measurement quantities, and also specifies

Methods for evaluating these measurements under steady-state and dynamic conditions and for compliance with standards:

The phasor measurement unit (PMU) defined in this document can be an independent physical unit or a function within a physical unit:

energy module: This document does not limit the hardware and software implementation of the PMU and the calculation method of the phasor, frequency and frequency change rate:

This document applies to synchrophasor measurement systems used in power systems:
