A Fault Section Location Method for Small Current Grounding System Based on HHT

2018 China International Conference on Electricity Distribution (CICED), 2018
A fault section location method for small current grounding system based on Hilbert-Huang Transform (HHT) is proposed. When a single-phase grounding fault occurs in the distribution network, the transient zero sequence current uploaded by the FTU on the feeder is decomposed by empirical mode decomposition (EMD) to obtain a limited number of intrinsic ...

Fault location of small current grounding system based on transient recorded wave data

2020 International Conference on Virtual Reality and Intelligent Systems (ICVRIS), 2020
The steady-state characteristics of the small current grounding system are not obvious, which leads to the low accuracy of the fault location results. Simplify the small current grounding system, analyze the transient recording data, and study the transient distribution characteristics of each component in case of fault.

Analysis and Application of Small Current Grounding System Transient Based on Mathematical Models

2010 International Conference on Electrical and Control Engineering, 2010
The single-phase grounding fault line selection in the distribution network has always been an outstanding problem of power system relay protection. One of the key reasons for fault line selection difficulty is that the fault current is correspondingly too weak to be detected effectively for the small current grounding system which is widely adopted in

Single-Phase Ground Fault Detection of Small Current Grounding System Base on Wavelets Analysis

2013
In order to improve the accuracy of line selection and reduce the possibility of single-phase ground fault in small current grounding system, this chapter solved two key problems including exploring the fault information of transient signals as much as possible and extracting the characteristic component of transient signals. This chapter proposed that

Simulation on Faulty Line Selection of Small Current Grounding System Based on Wavelet Transform

2010 Asia-Pacific Power and Energy Engineering Conference, 2010
A method of single phase ground fault line selection in distribution networks with the application of wavelet transform technique is presented in this paper. The modulus maxima of the wavelet transform are extracted to determine the moment of the single phase ground fault.
