Journal ArticleDOI
Fault-Induced Transient Detection Based on Real-Time Analysis of the Wavelet Coefficient Energy
TL;DR: In this article, a wavelet-based methodology for real-time detection of fault-induced transients in transmission lines, where the wavelet coefficient energy takes into account the border effects of the sliding windows, is presented.
Journal ArticleDOI
Accurate Two-Terminal Transmission Line Fault Location Using Traveling Waves
TL;DR: In this paper, an innovative two-terminal traveling wave (TW)-based fault location formulation is presented, which depends only on the time difference between the first incident TW and the successive reflection from the fault point, at both line ends.
Journal ArticleDOI
Real-Time Detection of Transients Induced by High-Impedance Faults Based on the Boundary Wavelet Transform
Flavio Bezerra Costa,Benemar Alencar de Souza,Núbia Silva Dantas Brito,J. A. C. B. Silva,W. C. Santos +4 more
TL;DR: In this paper, the wavelet coefficient energy with border distortions of a one-cycle sliding window designed for the real-time detection of transients induced by HIFs is presented.
Journal ArticleDOI
Real-Time Traveling-Wave-Based Fault Location Using Two-Terminal Unsynchronized Data
Felipe V. Lopes,Kleber M. Silva,Flavio Bezerra Costa,Washington Luiz Araújo Neves,Damasio Fernandes +4 more
TL;DR: In this paper, a two-terminal traveling-wave-based fault-location algorithm is proposed, which does not require the data from both line terminals to be synchronized and is applied in real time.
Journal ArticleDOI
A Wavelet-Based Transformer Differential Protection With Differential Current Transformer Saturation and Cross-Country Fault Detection
TL;DR: This paper proposes a fast and efficient transformer differential protection scheme with additional differential CT saturation and cross-country fault detection modules after the external fault detection, all of them based on the differential wavelet coefficient energy with border distortions in order to stabilize the relay during external faults and distinguish accurately CT saturation from cross-Country internal faults.
