Based on the Institute of Electrical and Electronics Engineers (IEEE) Standard C37.104-2012 Power Systems Relaying Committee report, topics related to auto-reclosing in transmission lines have been considered as an imperative benefit for electric power systems. An important issue in reclosing, when performed correctly, is identifying the fault type, i.e., permanent or temporary, which keeps the faulted transmission line in service as long as possible. In this paper, a multivariable analysis was used to classify signals as permanent and temporary faults. Thus, by using a simple convolution process among the mother functions called eigenvectors and the fault signals from a single end, a dimensionality reduction was determined. In this manner, the feature classifier based on the support vector machine was used for acceptably classifying fault types. The algorithm was tested in different fault scenarios that considered several distances along the transmission line and representation of first and second arcs simulated in the alternative transients program ATP software. Therefore, the main contribution of the analysis performed in this paper is to propose a novel algorithm to discriminate permanent and temporary faults based on the behavior of the faulted phase voltage after single-phase opening of the circuit breakers. Several simulations let the authors conclude that the proposed algorithm is effective and reliable.

“…In the case of multiple-phase faults, protection scheme trips all three phases of faulted line and blocks SPT&R, which is a common procedure in field applications. 22,23 After single-phase faults are detected and cleared, SPT&R is initiated and SPR success indicator is activated in both relays only for faulted phase. Afterwards, when no voltage period ends, SPR of faulted phase is initiated and SPR success indicator determines presence of the fault.…”

Summary A new transverse differential protection scheme with current‐based directional element enabling selectivity in the case of single‐pole tripping and reclosing is proposed for double‐circuit lines. No communication channel and voltage signals are required for proper operation of the protection. Selectivity of the proposed protection scheme is tested for both doubly fed and singly fed double‐circuit lines. Line with no fault and healthy phases of faulted line remain in operation during fault clearance time in such a way enhancing power system stability. A special single‐pole reclosing success indicator is proposed for differentiation between transient and permanent faults. After single‐pole reclosing event, selectivity of the protection is achieved using currents of healthy line as polarizing quantities. Selectivity testing is performed by extensive simulations of various fault events in the case of both doubly fed and singly fed untransposed double‐circuit line models using visual interactive simulator developed in MATLAB/Simulink.
