An accurate fault location technique for distribution lines with tapped loads using wavelet transform

A Bayesian Approach for Fault Location in Medium Voltage Grids With Underground Cables

“…If the TFI readings indicate that the fault is within the subinterval S FI,i , the range of the fault position is shortened, and the PMF and the pdf should be modified as in (8) and (9). In (8) and (9)…”

“…Moreover, Nouri et al [9] and Thomas et al [10] approached the problem by applying wavelet transform. It has been proposed to measure the time difference between the the traveling waves during the fault.…”

Fault Locating, Prediction and Protection (FLPPS)

“…A.2.4.2.5 An accurate fault location technique for distribution lines with tapped loads using wavelet transforms [27] Summary: This paper investigates the application of the wavelet transform in fault location techniques for distribution lines with tapped loads. Fault transient detectors (FTDs) based on a digital wavelet transform are installed at substation bus bars and load terminals to capture the time taken for the first fault-induced traveling wave to arrive and be synchronized with a GPS clock.…”

Comparison of ATP Simulation and Micro-processor Based Fault Location Using DFT

“…The use of GPS can make such a solution very expensive. Transient based fault location techniques for radial, meshed and distribution lines with tapped load power system configurations are described by a number of researchers (Nouri et al 2014, Magnago et al 1998and Nouri et al 2001, respectively. In impedance based methods, the ratio of extracted fundamental frequency of the voltage and current waveforms yields the impedance seen from the generator up to the point of fault.…”
