ACCELERATED TRIP OF POWER TRANSMISSION LINE BASED ON MATHEMATICAL MORPHOLOGY
L. Zou, P. Liu, Qianyu Zhao · International Journal of Power and Energy Systems · 2007
A set of series multi-resolution morphological gradient (SMMG) filters is proposed to detect the faint second changes of sequence currents and implement accelerated trip of power transmission lines, while a fault occurs in the second zone of distance protection, in this paper.
