Detection of high impedance faults in distribution networks using Discrete Fourier Transform
In this paper, a new method for extracting dynamic properties for High Impedance Fault (HIF) detection using discrete Fourier transform (DFT) is proposed. Unlike conventional methods that use features extracted from data windows after fault to detect high impedance fault, in the proposed method, using the disturbance detection algorithm in the network, the normalized changes of the selected fea...
متن کاملHigh impedance fault detection: Discrete wavelet transform and fuzzy function approximation
This paper presets a method including a combination of the wavelet transform and fuzzy function approximation (FFA) for high impedance fault (HIF) detection in distribution electricity network. Discrete wavelet transform (DWT) has been used in this paper as a tool for signal analysis. With studying different types of mother signals, detail types and feeder signal, the best case is selected. The...
متن کاملCross Entropy-Based High-Impedance Fault Detection Algorithm for Distribution Networks
The low fault current of high-impedance faults (HIFs) is one of the main challenges for the protection of distribution networks. The inability of conventional overcurrent relays in detecting these faults results in electric arc continuity that it causes the fire hazard and electric shock and poses a serious threat to human life and network equipment. This paper presents an HIF detection algori...
متن کاملHigh impedance fault detection in power distribution networks using time–frequency transform and probabilistic neural network
An intelligent approach for high impedance fault (HIF) detection in power distribution feeders using advanced signal-processing techniques such as time–time and time–frequency transforms combined with neural network is presented. As the detection of HIFs is generally difficult by the conventional over-current relays, both time and frequency information are required to be extracted to detect and...
متن کاملHigh Impedance Fault Detection On Distribution Feeders
The ability to detect High Impedance (HiZ) faults has been a topic of research and development for over 30 years. About seven years ago, products began to appear on the market that could securely perform this function. Over this time period, several hundred HiZ detection devices have been placed in service and have performed to expectations. This paper reviews the operating principle of HiZ fau...
