Abstract: Now-a-days Phaselet Transform based distance relaying scheme is being proposed in the literature for high speed relaying in high voltage lines to obtain response times less than one quarter cycle. Phaselets are gaining importance due to their better transient response compared to Full Cycle Discrete Fourier Transform (FCDFT) during dynamic situations. But there are few operational issues with phaselets that have to be observed closely. In this paper, a single end feed test system with phaselet/FCDFT was simulated in MATLAB platform with various test cases. Then the performance of phaselet based distance relaying scheme is compared with the conventional Full Cycle Discrete Fourier Transform. Results are reported in this paper.
