This paper presents a novel approach for fault location in distribution system using neural network. The voltage and current in the instance of fault are used for training. Different faults are simulated in a specific feeder by PSCAD software. The MATLAB and EMTDC are used for simulation in this work. The results of case studies show the capability of neural networks in fault location with negl...

In this paper, an approach is proposed for accurate locating of single phase faults in transmission lines using voltage signals measured at one-end. In this method, harmonic components of the voltage signals are extracted through Discrete Fourier Transform (DFT) and are normalized by a transformation. The proposed fault locator, which is designed based on Random Forests (RF) algorithm, is train...

The main content of logic circuit fault detection includes describing circuit to be diagnosed, determining fault and circuit initial information, generating circuit location test set. In this study, LASAR is used to carry out the logic circuit simulation so as to create such documents as fault dictionary, node truth value table, etc. for the preparation of fault detection. Due to the limitation...

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...

This Paper focuses on detecting, classifying and locating faults on electric power transmission lines. Fault detection, fault classification and fault location have been achieved by using artificial neural networks. Feedforward networks have been employed along with backpropagation algorithm for each of the three phases in the Fault location process. Analysis on neural networks with varying num...

Abstract— An important aspect of network management is fault management, i.e., determining, locating, isolating, and correcting faults in the network. We study modeling of communication network protocols, and their fault detection, fault identification and fault location in the discrete event systems diagnosis framework. Our approach provides a systematic way of performing fault diagnosis in ne...

A new one-end fault location algorithm designated for series-compensated transmission lines is delivered in this paper. It is based on differential equation approach, which allows good reflection of the dynamic phenomena relevant for faults occurring behind the bank of series capacitors (SCs) equipped with metal oxide varistors (MOVs). As a result of that, a good stabilisation of the estimation...

Standard IDDQ testing is limited by the ability to distinguish a small fault current from a large background leakage current: this limitation is overcome in FPGAs by differential IDDQ testing. Partitioning of interconnects—dividing the interconnect resources of an FPGA into groups—further increases the detectability of a fault current. Fault location can be achieved by iteratively applying part...

Fault location has been studied deeply for transmission lines due to its importance in power systems. Nowadays the problem of fault location on distribution systems is receiving special attention mainly because of the power quality regulations. In this context, this paper analyses the influence of the capacitance of cables and compensation capacitor banks when impedance-based algorithms are use...
