This paper proposes two procedures to compute the quality of phasor estimations. These procedures will 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 by requiring a reduced number of numerical operations to make its implementation possible 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.
