Time-time-transform-based fault location algorithm for three-terminal transmission lines

摘要

In this study, time-time transformation is employed to reveal the time of arrival of the fault-generated travelling waves, where these time instants are then used in a fault location algorithm for three-terminal single- and double-circuit transmission lines. The performance of the proposed fault location algorithm under different line lengths and fault conditions such as fault types, faulted sections, fault locations, fault resistances and fault inception angles are investigated and the high accuracy of the proposed method is approved in all these conditions even, in fault inception angle of zero and for faults on tap point.
