Abstract

The paper investigates the accuracy of the synchrophasor estimation provided by the Interpolated Discrete Fourier Transform (IpDFT) algorithm under both steady state and dynamic conditions. Dynamic performances of the proposed algorithm are evaluated using the test signals suggested for the M-class performance in the IEEE Standard C37.118.1:2011 about synchrophasor measurements for power systems. In all the performed tests the achieved Total Vector Errors (TVEs) are always smaller than the related accuracy thresholds specified in the Standard.
