“…The criterion used in [4] is the faulted phase voltage THD while the method in [15] uses wavelet packet transform and an adaptive threshold level based on the harmonic of the faulted phase voltage. The proposed criterion in [19] is based on a low-pass filter and the cascaded delayed signal cancellation technique, which is applied to the faulted phase voltage. The approach proposed in [25] is a method based on the voltage harmonic content measurement.…”

“…Then the ratio of faulty phase terminal voltage to neutral small reactance voltage for the measured and calculated values is achieved and the difference between them is used as a threshold for fault type recognition. In order to detect transient and permanent faults in [19], a low-pass filter and the cascaded delayed signal cancellation technique are applied to the voltage of the faulted phase. Transient faults are identified from permanent faults by using the average distortion rate and a threshold.…”

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.

“…Shunt reactors are widely used in high voltage transmission lines to improve power system stability and line voltage profile regulation [23]. The methods presented in [24][25][26][27][28][29][30] are effective for shunt compensation transmission lines. In these methods, the beat frequency generated after the quenching of the secondary arc was used to detect the quenching of the secondary arc.…”

“…Increasing faulty phase reactive or active power after secondary arc extinction was used to detect arc extinction for shunt compensated transmission lines. In [29], based on the cascaded delayed signal cancellation technique and using the faulted phase local voltage of the shunt compensated line, the average distortion rate was calculated to identify the fault nature and clearance.…”

This paper presents a reliable and fast index to detect the instant of arc extinction for adaptive single-pole automatic reclosing (ASPAR). The proposed method is a simple technique for ASPAR on shunt compensated transmission lines using the Hilbert–Huang Transform (HHT). The HHT method is a combination of the empirical mode decomposition (EMD) and the Hilbert transform (HT). The first intrinsic mode function (IMF1) decomposed by EMD, which contains high frequencies of the faulty phase voltage, was used to calculate the proposed index. HT calculates the first IMF spectrum in the time-frequency domain. The presented index is the sum of all frequency contents below 55 Hz, which remains very low until the fault clearance. The proposed method uses a global threshold level and therefore no adjustment is needed for different transmission systems. This method is effective for various system configurations including different fault locations, line loading, and various shunt reactor configurations, designs, compensation rates, and placement. The performance of the method was verified using 324 test cases simulated in electromagnetic transient program (EMTP) related to a 345 kV transmission line. For all the test cases, the algorithm successfully operated with an average reclosing time delay of 32 ms.
