This document defines the measurements of synchronized phasors, frequency, and frequency rate of change, specifies the time scale and synchronization requirements for the three measured quantities, and also specifies the methods for evaluating these measured values under steady-state and dynamic conditions and compliance with the standard sexual demands. The phasor measurement unit (PMU) defined in this document can be an independent physical unit or a functional module within a physical unit. This document does not limit the implementation of hardware and software of the PMU and the calculation method of phasor, frequency and frequency change rate. This document applies to synchrophasor measurement systems used in power systems.
