Abstract: The polar coordinate system fast time-domain algorithm is more efficient than the original back-projection (BP) algorithm. However, it still has complex coordinate transformation and 2-D ...
Abstract: Today high speed protection of power system elements is necessary and realizable. This paper introduces time-domain protection techniques for transmission lines using voltage and current ...
