“…These methods, firstly, determine whether a fault is permanent or transient, and if the fault is in transient nature, its secondary arc extinction time is estimated. Generally, voltage waveforms at the sending and receiving ends of TLs are used for the analyses [4][5][6][7][8][9][10][11][12]. In some studies, faulted phase currents are also used for successful operation [6].…”

“…However, it is pointed out that successful identification of fault types is mainly dependent on the chosen threshold value which is known to be system dependent [4]. As an alternative to the RMS calculation algorithm, Fast Fourier Transform (FFT) based methods are also found in the literature [5][6][7][8].…”

“…Since the voltage waveform of the faulted phase during the secondary arc is greatly distorted compared with the waveform after the secondary arc extinction, in Reference [13] the total harmonic distortion (THD) value of this voltage is used to determine an appropriate time for reclosing. The fundamental component of the zero sequence power at the both ends of a line is used in Reference [14] to detect the extinction time of the secondary arc.…”

SUMMARYThis paper proposes a new algorithm for adaptive single pole auto-reclosing (SPAR) using discrete wavelet transform (DWT). The faulted phase voltage signal is captured at a sampling rate of 2.5 kHz. The sym8 wavelet function is used to decompose the signal into level 1 and to define an index function (INDF), which is obtained from the sum of absolute values of detail coefficients of the captured signal at the level 1 resolution. Finally, a decision function (DEF) is defined by computing the second derivative of the INDF. By evaluating the sign of the DEF, transient (arcing) faults are distinguished from permanent faults and also the secondary arc extinction instant can be identified. The significant advantage of the proposed algorithm is that it does not require any threshold level and therefore its performance is independent of fault location, line parameters and operating conditions. Furthermore, it can be used in transmission lines with reactor compensation. The proposed method has been successfully tested under a variety of fault location and load angle on a 400 kV overhead line, with and without reactor compensation, using the Electro-Magnetic Transient Program. The test results validate the algorithm ability in distinguishing between arcing and permanent faults and determining the instant of secondary arc extinction.

Summary Single‐phase‐to‐ground faults (SFs) could be characterized by multiple aspects, like time domain and frequency domain. There is no unified classification standard for such faults. Previous studies usually focused on detection and feeder‐selection techniques for SFs. This paper presents the classification architecture and recognition method for SF in nonsolidly earthed distribution networks. On the basis of the waveform data recorded by remote fault indicators and other recording devices, steady and transient characteristics of SFs are analyzed, and the faults are defined and classified into multiple levels. In each level, different kinds of SFs are recognized by quantization of time domain features, frequency domain features, and etc. It is rigorously tested through field data and artificial test data. Test results show that the proposed method could effectively recognize different kinds of SFs.
