Development of Fault Location for Distributed Parameter Transmission Lines of a Power System

This paper proposes a novel application of an improved cuckoo search (ICS) algorithm for locating faults on distributed parameter transmission lines of a power system. Fault types discussed are three line faults (L-L-L), three lines to ground faults (L-L-L-G), double line faults (L-L), double lines to ground faults (L-L-G) and single line to ground faults (L-G). Numerical results have been demonstrated that the ICS algorithm is efficient in locating faults on the distributed parameter transmission lines of the power system, as well as achieve satisfactory performances. Additionally, the results of using the ICS algorithm are also compared with those of using other existing algorithms showing the superiority of the proposed algorithm in the fault location application.
