“…The arcing fault model introduced in [27] is utilized in this paper. The authors in [27] differentiated between arcs and categorized them into two types: 1) primary arcs occurring during the short circuit SLG fault and 2) secondary arcs resulting from capacitive coupling between healthy and faulty phases. Unlike the other models, this model has very close proximity to the practical results and is suitable for high voltage TLs.…”

An appropriate method is proposed for identifying permanent faults from transient faults in double-circuit transmission lines. This method could be used in adaptive single phase auto-reclosures in order to diagnose between permanent and transient faults, determine extinguishing time of the secondary arc, and calculate issuing time of reclosing commands during the occurrence of transient single phase to ground faults. The proposed method is based on harmonic analysis of the adjacent healthy circuit and could be an effective solution for blocking permanent disconnection of the power flow, improving stability, and maintaining the power network synchronism. In this paper, transient and permanent faults are simulated on a typical power system, and then current harmonics of the healthy circuit terminal are extracted and finally the proposed index for identifying the fault type is applied. In the case of transient faults, this method determines the minimum time needed for a fast successful adaptive reclosing in the network and thus prevents instability and nonsynchronism in both sides of the transmission line. Results of the various simulations run in EMTP-RV verifies accurate performance of the proposed approach.

The protection of multiterminal transmission lines is a challenging task due to possible infeed or outfeed currents contributed from the taped lines. As a result, the first zone reach of a noncommunication-based scheme (e.g., impedance-based distance relays) usually cannot be extended more than a small portion beyond the tap point. This paper presents a protection technique based on the high-frequency transients generated by the fault to cover almost the total length of multiterminal transmission lines. For this purpose, appropriately designed line traps are installed at terminals of the protected transmission line, and the support vector machine is used to classify the internal and external faults based on the frequency spectrum of the current signals decomposed by the wavelet transform. Extensive simulation studies indicate that the proposed approach is well capable of discriminating between the internal and external faults and provides a very fast, secure, and reliable protection technique.Index Terms-Line trap, multiterminal transmission line, support vector machine (svm), transients-based protection.
