This paper presents a new methodology for evaluation of digital filter techniques, whose main goal is to improve the insight about the advantages and disadvantages of the half- and one-cycle phasor estimation performance during transients. The voltage and current phasor estimation during transients affects the distance relay performance. With the adopted methodology, it is possible to identify which filters are not suitable for the distance protection. Therefore, the dynamic behaviour of the… CONTINUE READING
