“…Some procedures analyze the fundamental waveforms of pre and post-fault voltages and currents (e.g., [4]- [6]), whilst others are based on the analysis of the fault-originated electromagnetic (EM) transients, i.e., the traveling waves generated by the fault itself (e.g., [7]- [16]). …”

Abstract-The paper presents a procedure for fault location in distribution networks, based on the use of the integrated time-frequency wavelet decompositions of the voltage transients associated with the fault-originated travelling waves. The proposed analysis of time-frequency wavelet decompositions has been found to improve the identification accuracy of the frequencies associated to the characteristic patterns of a fault location with respect to a sole frequency-domain wavelet analysis. Several laboratory fault tests, carried out by means of a reduced-scale model of a distribution feeder, are used to illustrate the characteristics and assess the performances of the proposed improved procedure. The paper also illustrates the application of the proposed procedure to a transient, originated by a permanent phase-to-phase fault, measured in a real distribution network in which a post-test analysis has identified the faulted branch.

“…Roughly, it is possible to classify three different kinds of methods: (a) travelling-wave based methods [2,3]; (b) high-frequency components based methods [4,5]; and (c) impedance-based methods [6][7][8]. Travelling wave-based methods depend on wave propagation, which is a complex phenomena that is difficult to analyze with detailed precision due to sensitive dependency to system parameters and network configurations [9].…”

“…Travelling wave-based methods depend on wave propagation, which is a complex phenomena that is difficult to analyze with detailed precision due to sensitive dependency to system parameters and network configurations [9]. High-frequency methods require specially tuned filters and high sampling rates to cope with high-frequency components of voltage and current waves that travel between the fault and the line terminals [5].…”

a b s t r a c tPower distribution utilities often use impedance-based methods for locating faults along their feeders. For feeders with laterals, these techniques may identify different possible locations for the same fault. This leads to higher costs and longer restoration time. In order to improve impedance-based methods, faultedcircuit indicators (FCI) can be allocated along the feeder to reduce, or even eliminate, the uncertainty about the fault location. This paper proposes a technique for optimally allocating a given number of FCIs along distribution feeders using the Chu-Beasley genetic algorithm to solve the optimization problem. The proposed objective functions measure the number of locations that are suspected to be the actual fault location or the distance among them. Additionally, it is possible to consider the presence of priority areas. We present results for the IEEE 34-bus system and for a 475-bus actual system. The results show the effectiveness of the proposed technique in improving impedance-based fault location methods.

“…Extensive research has been done over many years on fault location for radial distribution lines with measurements available at a single location. Generally speaking, fault location methods can be divided into impedance based [1]- [8] and traveling wave based [9]- [12]. Impedance-based methods are more popular among the utilities because of their relative simplicity [3].…”

This paper proposes a new single phase-to-ground short-circuit fault location algorithm for overhead three-phase radial distribution lines with single-ended measurements using the sinusoidal steady-state analysis method. By using this approach, two sinusoidal signals with different frequencies are first injected to the faulted line. By measuring the voltages and currents at the sending end and solving some nonlinear distributed-parameter equations, the distances and resistances of all possible fault candidates can be determined. A feature extraction method is derived to distinguish the actual fault from other pseudofault candidates. A fault locator based on the proposed approach is designed and implemented for a real-world problem. Physical model experiments and the field tests on radial distribution lines are presented to validate the proposed fault location approach.
