Abstract
Phasor Measurement Unit (PMU) is a basic tool for electric power system monitoring. The IEC/IEEE 60255-118-1 standard defines measurement compliance evaluation with boundaries imposed on phasor, frequency, and rate of change of frequency estimation errors. However, in field measurements even the phasors reported by compliant PMU may be erroneous due to transient conditions. For that reason, along with the reported phasors, additional information, proportional to phasor estimation errors, should also be provided. Real-time phasor validation can be attained based on residual signal, i.e. the difference between the analyzed waveform and a sinusoid reconstructed from the measured phasor. In the paper two real-time phasor validation factors are defined: one in the time domain and one in the frequency domain. It is shown that the proposed phasor validation factors are proportional to phasor estimation errors and thus are useful for flagging invalid phasors. In the paper results for the proposed phasor validation factors are presented for a PMU implemented with the flat-top window, and with the Hamming window. The comparison with the popular transient monitor is provided for the standard compliance tests and also for the field measurements of voltage supplying arc furnace.
