A Fast Quality Assessment Algorithm for Phasor Measurements

Summary form only given. This paper proposes two procedures to compute the quality of phasor estimations. These procedures enable phasor measurement units (PMUs) to report, with each measurement, the quality of the estimated phasor. The procedures rely solely on measured data and are independent of the algorithm used to obtain the phasor estimate. These procedures were conceived requiring a reduced number of numerical operations to make possible its implementation in microcontroller based PMUs. Perhaps, the most important contribution of this paper is the suggestion that phasor measurements should, along with the time stamp, carry information on the quality of the phasor estimation
