Phasor measurement units (PMUs) are rapidly being deployed in electric power networks
across the globe. Wide-area measurement system (WAMS), which builds upon PMUs and …

In this paper, a method of samples of instantaneous currents and voltages is proposed,
which allows to extract only sinusoidal information necessary for correct operation of digital …

In this paper, the basics of dynamic phasor (DP) modelling has been introduced by
employing a simple RL-series circuit. In the example, the actual time-domain simulation and …

The measured impedance of distance protections is affected by an error because of the
combined effects of fault resistance and prefault load. This study proposes the …

High penetration of inverter-based resources (IBRs) in modern power grids reduces system
inertia and short circuit levels, emphasizing the need for fast and reliable transmission line …

This article presents a new methodology for transmission line protection that uses higher-
order statistics (HOS), cumulants, and artificial neural networks (ANNs). The main objective …

This paper presents the use of Higher Order Statistics (HOS) and Artificial Neural Networks
(ANNs) for distance relaying purposes. The main objective is to design a distance relay …

Traditional protective relays work based on a frequency domain since many decades ago.
Over the last decades, the fundamentals of a Discrete Fourier Transform (DFT) have shown …

Capacitive voltage transformers (CVTs) are widely used in line voltage measurement of
EHV/UHV power systems. When a fault occurs, CVT measurements may contain severe …

Modern switches disable short circuits for two to three periods of frequency, so the
requirements for algorithms implementing emergency control are very strict. Therefore, the …
