Full-cycle Fourier and cosine phasor filtering systems are typical implementations of numerical distance relays with a response time of close to one cycle. Fast subcycle numerical distance elements are useful, especially for extra high voltage/UHV transmission systems (400 kV and above). Fast subcycle numerical relaying methods such as half-cycle Fourier method, phaselets, least error squares, traveling wave, and wavelet based methods have been proposed in the literature. In this paper, first… CONTINUE READING
