Journal ArticleDOI
High-impedance fault detection in distribution networks with use of wavelet-based algorithm
TL;DR: In this paper, a wavelet-based high-impedance fault (HIF) detector has been proposed for distribution networks with the application of wavelet transform technique, which can be used for HIF detection independent of the network neutral-point grounding mode.
Book ChapterDOI
Application of Artificial Neural Networks
TL;DR: The signal processing methods and algorithms described in preceding chapters were expressed in form of explicit equations, transfer functions and/or logic rules, either in crisp or in fuzzy versions, but specific tasks and power system operation conditions when other solutions should be applied.
Journal ArticleDOI
New ANN-Based Algorithms for Detecting HIFs in Multigrounded MV Networks
TL;DR: In this paper, two new ANN-based algorithms for arcing high impedance fault (HIF) detection in multigrounded mediumvoltage (MV) distribution networks are presented.
Journal ArticleDOI
Power system frequency estimation
Janusz Szafran,Waldemar Rebizant +1 more
TL;DR: In this article, a new algorithm of power system frequency estimation is presented, which applies orthogonal signal components obtained with use of two Orthogonal FIR filters and ensures 1.5 mHz accuracy of estimation over typical (± 2 Hz) range of measured frequency deviation.
Journal ArticleDOI
Correction of Current Transformer Transient Performance
TL;DR: In this article, the fundamental frequency component amplitude and the decaying DC component in each period were estimated for each period, and the accuracy of the estimation was shown to be excellent for the case of the CT primary current.
