Detection, classification, and location of faults in power transmission lines
This paper presents a pattern recognition approach for current differential relaying of power transmission lines. The current differential method uses spectral energy information provided through a new Fast Discrete S-Transform (FDST). Unlike the conventional S-Transform (ST) technique the new one uses different types of frequency scaling, band pass filtering, and interpolation techniques to re...
متن کاملArcing Fault Detection and Fault Location on Hv Transmission Lines
In this paper a new numerical algorithm for fault distance calculation and arcing fault recognition, based on one terminal data and derived in the time domain, is presented. The algorithm is derived for the case of most frequent single-phase line to ground fault. The faulted phase voltage is modelled as a serial connection of the fault resistance and the arc voltage. The fault distance and the ...
متن کاملArtificial Neural Network Based Method for Location and Classification of Faults on a Transmission Lines
Transmission lines, among the other electrical power system components, suffer from unexpected failures due to various random causes. These failures interrupt the reliability of the operation of the power system. When unpredicted faults occur protective systems are required to prevent the propagation of these faults and safeguard the system against the abnormal operation resulting from them. Th...
متن کاملNumerical Methods for the Analysis of Power Transformer Tank Deformation and Rupture Due to Internal Arcing Faults
Power transformer rupture and fire resulting from an arcing fault inside the tank usually leads to significant security risks and serious economic loss. In order to reveal the essence of tank deformation or explosion, this paper presents a 3-D numerical computational tool to simulate the structural dynamic behavior due to overpressure inside transformer tank. To illustrate the effectiveness of ...
