The method employs a second-order generalized integrator (SOGI) quadrature signal generator (QSG) filter to attenuate the self-interference of the fundamental tone. Inspired by other static state-of-the-art SE methods, the algorithm combines a three-point IpDFT with a three-cycle Hanning window delivering a reduction in the total computational cost. Its performance with respect to all the operating conditions defined by the IEC/IEEE Std. 60255–118 is assessed and compared with another state-of-the-art technique. Furthermore, a computational complexity analysis is performed to assess the potential viability of the proposed SE algorithm for its implementation in embedded devices.Performance evaluationInterference cancellationMeasurementsEstimationFiltering algorithmsSignal generatorsPhasor measurement unitsIEC/IEEE Std 60255-118-1-2018Second-order generalized integratorDiscrete Fourier transformInterpolated DFTPhasor measurement unitSynchrophasor estimationtext::conference output::conference proceedings::conference paper
