An ANN Based Fault Diagnosis System for Tapped HV/EHV Power Transmission Lines
This paper presents a design for a fault diagnosis system (FDS) for tapped high/extra-high voltage (HV/EHV) power transmission lines (TL's). These tapped lines have two different protection zones. The proposed approach reduces the cost and the complexity of the FDS for these types of lines. The FDS, basically, utilizes fifteen artificial neural networks (ANN's) to reach its output diagnosis. Th...
متن کاملANN Based Directional Fault Detector/Classifier for Protection of Transmission Lines
An accurate fault detection, classification and direction estimation of double end fed transmission lines based on application of artificial neural networks is presented in this paper. The proposed method uses the phase voltage and current available at only the local end of line. This method is adaptive to the variation of fault inception angle, fault location and high fault resistance. The alg...
متن کاملShort: a Knowledge-based System for Fault Diagnosis in Power Transmission Networks
This paper presents SHORT a knowledge-based system for fault diagnosis in power transmission networks. Differently from previous approaches to this very complex diagnostic problem, SHORT includes a knowledge representation formalism, named plot, capable of taking into account temporal aspects of component behavior, and solves the diagnostic problem as an instance of a more general class of temp...
متن کاملPattern Recognition Approach for Fault Identification in Power Transmission Lines
This paper presents an improved algorithm for fault detection and classification of transmission line fault current signals using MATLAB/SIMULINK. The proposed algorithm presents a fault discrimination method based on the three-phase current and voltage waveforms measured when fault events occur in the power transmission-line network. The algorithm for fault classification employs wavelet multi...
متن کاملA Novel Fault Detection and Classification Approach in Transmission Lines Based on Statistical Patterns
Symmetrical nature of mean of electrical signals during normal operating conditions is used in the fault detection task for dependable, robust, and simple fault detector implementation is presented in this work. Every fourth cycle of the instantaneous current signal, the mean is computed and carried into the next cycle to discover nonlinearities in the signal. A fault detection task is complete...
