Animating transmission-line transients with BOUNCE

Fault location and classification in non-homogeneous transmission line utilizing breaker transients

In this paper, a single-ended fault location method is presented based on a circuit breaker operation using the frequencies of traveling waves. The proposed method receives the required data from voltage traveling waves with the aid of Fast Fourier Transform (FFT) and Wavelet Transform. Then, the Artificial Neural Network (ANN) identifies fault type and determines its location. In order to eval...

Back-flashover Investigation of HV Transmission Lines Using Transient Modeling of the Grounding Systems

The article presents the transients analysis of the substation grounding systems and transmission line tower footing resistances which can affect to the back-flashover (BF) or overvoltage across insulator chain in an HV power systems by using EMTP-RV software. The related transient modeling of the grounding systems is based on a transmission line (TL) model with considering the soil ionization....

Direct Phase-domain Calculation of Transmission Line Transients Using Two-sided Recursions

This paper presents a new method for the simulation of electromagnetic transients on transmission lines. Instead of usmg Lonvolutions of the input vanables only, we perform short Lonvolutions with both mput and output variables The result is a method of Two-sided Recursions (TSR). which is comparable in efficiency with the existmg recursive convolutions or with theu equivalent state vanable for...

Wavelet Based Analysis for Transmission Line Fault Location

Abstract This paper presents wavelet based analysis for transmission line fault location. Faults in power transmission lines cause transients that travel at a speed close to the speed of light and propagate along the line as traveling waves (TWs). Traveling wave theory is utilized in capturing the travel time of the transients along the monitored lines between the fault point and the protective...
