During faults, the voltage and current signals available to the relay are affected by the decaying DC component and harmonics. To make proper decisions, most of the relaying algorithms require the fundamental frequency phasor information immune to decaying DC effect and harmonics. Conventional Fourier and LES phasor estimation algorithms are affected by the… CONTINUE READING
