Synchrophasor measurement

Synchrophasor measurements are a new emerging field in the area of power system research. While this technology is relatively new, it has been shown that extracting synchrophasor measurements from the power grid, for use in power system monitoring and control applications, results in improved performance and reliability of the power grid. Synchrophasors combine the phasor representation of AC waveforms with a precise, universal time stamp. There are four main quantities associated with synchrophasor measurements: (i) phasor magnitude, (ii) phasor angle, (iii) fundamental frequency and (iv) rate of change of frequency (ROCOF). Instruments that extract these four measurements and transmit the results to a central data collection point are called PMUs (Phasor Measurement Units). The goal of this project is to expand the work on a recently completed ENGAGE grant and develop a fully-functional measurement device with two complementary functions: (a) a phasor measurement unit with fast transient response times and (b) a high resolution digital waveform recorder. Archival of data will be useful for synchrophasor accuracy verification and also will support the emerging field of Power Quality Data Analytics. The end goal is to show the feasibility of a product concept that could then be developed quickly and brought to market. This device would be the first of its kind in the power measurement industry.
