Synchronized phasor measurements have become a practical proposition only during the last few years. As such, their potential for use in power system applications has not yet been fully realized. Anticipating that this technology is about to take off, the Power System Relaying Committee of the IEEE has developed a standard which defines the interface between the Global Positioning System (GPS) and the Phasor Measuring Unit (PMU), and for the communication link between the PMUs and a remote site. The standard (SYNCHROPHASOR) will be published during 1996, and should facilitate the widespread application of this emerging technology. The standard defines the following features of the PMU: format of the message which contains the phasor data, time-tag specification, data frame composition, and a check sum. The standard also includes a specification for the synchronizing pulses which may be produced by a GPS receiver, or by some other synchronizing source. Synchronized phasor measurement units may well be the universal power system transducer of the future. It will serve the needs of all monitoring and control functions in power system control centers, and in many of the back-up relaying functions.
