Fault Location Technique for UHV Lines Using Wavelet Transform
The paper illustrates a procedure based on the continuous-wavelet transform (CWT) for the analysis of current transients due to line faults. Considering roundly reliability and accuracy of one terminal fault location system for transmission lines, a single-ended continuous wavelet Transform (CWT) based fault location algorithm has been presented in this paper. Wavelet transform is a powerful ma...
متن کاملfault location in power distribution networks using matching algorithm
چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
ANFIS Based Fault Location for EHV Transmission Lines
An accurate fault location method for EHV transmission lines is described in this paper, which is based on adaptive Network Based Fuzzy Inference System (ANFIS). The faulted voltages and currents of one line end are used in this technique. The waveforms of voltages and currents include fault information and some of their components is used for fault location. Neuro fuzzy networks come to be a p...
متن کاملA GA-based Feature Optimization Technique for Bearing Fault Diagnostics
Rolling-element bearings are widely used in various mechanical and electrical systems. A reliable online bearing fault diagnostic technique is critically needed in industries to detect the occurrence of a fault so as to prevent system’s performance degradation and malfunction. To improve the fault diagnostic reliability and efficiency, a genetic algorithm based feature optimization technique is...
متن کاملFault Location Using the Distributed Parameter Transmission Line Model
Earlier work at Texas A&M University led to the development of transmission line fault location algorithms that were based on synchronized sampling of the voltage and current data from the two ends of the line. The line models used in the algorithms were based on lumped parameter models for electrically short lines, or lossless distributed parameter models for electrically long lines. In this p...
