Wavelet based transmission line fault analysis: A literature survey

TLDR
A comprehensive review of the techniques employed in fault analysis which have evolved over the last decade is presented in this article, which mainly focuses on the implementation of discrete wavelet transform (WT), multi-resolution analysis (MRA) artificial neural networks (ANN) and fuzzy logic for fault analysis.
Abstract
Transmission lines faults are an inevitable part of any power system. They cause a disruption in the power supply, which is undesirable. With an ever-increasing demand for better performance and minimal interruptions, accurate fault analysis is necessary to restore a system to its normal operation by detecting and clearing the transmission line fault. This paper presents a comprehensive review of the techniques employed in fault analysis which have evolved over the last decade. This review paper mainly focuses on the implementation of discrete wavelet transform (WT), multi-resolution analysis (MRA) artificial neural networks (ANN) and fuzzy logic for fault analysis.

Robust functional analysis for fault detection in power transmission lines

TL;DR: In this paper, the authors proposed robust functional analysis of power transmission lines to represent the behavior of the electrical signals and to estimate the upper and lower limits under normal operating conditions, but the results showed that the estimation is biased and relies on statistical assumptions that do not hold in practice.

A theory for multiresolution signal decomposition: the wavelet representation

TL;DR: In this paper, it is shown that the difference of information between the approximation of a signal at the resolutions 2/sup j+1/ and 2 /sup j/ (where j is an integer) can be extracted by decomposing this signal on a wavelet orthonormal basis of L/sup 2/(R/sup n/), the vector space of measurable, square-integrable n-dimensional functions.

Wavelets and electromagnetic power system transients

TL;DR: The wavelet transform was introduced as a method for analyzing electromagnetic transients associated with power system faults and switching as mentioned in this paper, and it is more appropriate than the familiar Fourier methods for the nonperiodic, wide-band signals associated with EM transients.
