    Adaptive Single Ended Protection Scheme for parallel Transmission Lines
    (IEEE, 2017) Mourad, Dina; Shehab Eldin, E. H.
    This paper presents a novel and adaptive non communication based protection proposal. It, also, provides a proposed transform, which is named the Akrap transform, to extract the transient components. The proposal uses the positive sequence currents and the Akrap transform to protect the double-circuit transmission line. The suggested proposal consists of two steps; while Step 1 detects internal faults, Step 2 identifies the faulted circuit. The proposal uses the three phase currents measurements at one end of the double circuit line. Thus, there is no need to any communication links. The proposal is evaluated with ATP-EMTP versatile simulations. Moreover, it has advantages like its protection to the total line length and the simple and fewer numbers of equations. It does not depend on the impedances of sources, the initial fault conditions as type of fault, inception time of fault, distance of fault, and resistance of fault and the current transformer saturation.
