Abstract
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.
Highlights
It is clear that electric power systems (EPS) have been considered as one of the most important developments of humanity, and its principal objective is to supply electric power maintaining a very high level of continuity of service
If the voltage imposed by the supply system was greater than the restarting voltage when the secondary arc crosses zero, the arc was kept in a conduction state, otherwise, it remained in a partial or final condition
The study shows that the analysis of principal components (PCs) generates 24 PCs, shown in Table 1, which were analyzed as follows: Table 1
Summary
It is clear that electric power systems (EPS) have been considered as one of the most important developments of humanity, and its principal objective is to supply electric power maintaining a very high level of continuity of service. In can this time (DT) will elapse and the breakers of each phase will be closed at each extreme of the TL In this accelerate much, and the loss of synchronism the DT, rotors which of would be catastrophic situation, too there would because no voltage source to feed the during arc. Considering the possible problems of three-phase reclosing, and if the temporary two phases are kept energized during theisfault period, whilereclosing the faulted phase faulthealthy is usually single-phase, an effective method the single-phase. In becomes this case,dethe fault is usually single-phase, an effective method is the single-phase reclosing [10,11] In this case, energized temporarily arc is cleared. The traditional relay algorithm recloses the faulted phase the fault type temporary.
