Periodic sampling of a continuous time-domain waveform, consisting of a power system voltage or current signal, to obtain a discrete time-domain function; b. Transforming a discrete time-domain function to a discrete frequency-domain function; c. Estimating from the discrete frequency-domain function the instantaneous parameters of a synchrophasor of the sampled continuous time-domain waveform, the instantaneous parameters comprising a frequency, an amplitude and a phase angle. The method is directed to an improvment of the enhanced IpDFT-based synchrophasor estimation which takes into account interharmonic tones.SynchrophasorsPhasor Measurement UnitsTime synchronizationPower SystemsMonitoringReal time systemspatentUS11204375US2020200806EP3635417WO201822486659350990
