Selection of suitable features for fault classification in transmission line

2015 IEEE International Conference on Control System, Computing and Engineering (ICCSCE), 2015
Power system protective relaying is an important feature for efficient and reliable power flow operation. The traditional fault classification scheme using the steady state component is easily affected by environment factors. Then, it is important to provide power protection scheme that offers a better classification performance based on fault ...

Fault Line Selection Based on the Frequency Characteristics of Feeders

2020 IEEE 3rd Student Conference on Electrical Machines and Systems (SCEMS), 2020
In resonant grounding system, the arc suppression coil could improve power supply reliability by compensating for capacitive fault current, which also makes fault line selection more difficult. This paper presents a fault line selection scheme which produces the line selection signal without changing the existing equipment.

A Fault Line Selection Method by Resistive Current for Single-Phase Earth Fault in Network

Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering, 2019
Aiming at the question of selecting fault line when single-phase grounded in neutral "point" ineffective ground system, according to resistive current, a criterion of line selection is proposed, and its feasibility is analyzed in depth. When the system detects zero-sequence voltage, the medium resistance is put into the neutral point of the system, and

New approach to select the fault line based on transient energy features of fault phase

2021 IEEE International Conference on Computer Science, Electronic Information Engineering and Intelligent Control Technology (CEI), 2021
A new approach for fault line detection using Wavelet energy feature of fault-phase transient current is proposed. This novel method utilizes the phase selection function of insulation monitoring system and the differences of transient current between fault line and non-fault line.

A New Method for Fault line Selection of Four-Parallel Transmission Lines

2010 Asia-Pacific Power and Energy Engineering Conference, 2010
Based on the theory of twelve sequence components, this paper analyzes the single circuit line fault characteristics of four-parallel transmission lines on the same tower. By use of the relationship of different amplitudes and phases between each sequence components, a new method is proposed for fault line selection of four-parallel transmission lines.

Fault Line Selection with Parallel Supply Lines in Mine Power Systems

Advanced Materials Research, 2012
In mine power systems, false operation and failure operation of relays in parallel supply lines often take place when single phase grounding fault occurs. A novel method based on phase-to-phase current difference is proposed as line selection criterion in this paper.

Fault Line Selection and Location of Distribution Network Based on Fault Recording Data

2020
Single-phase grounding fault line selection is a long-standing problem in the distribution network. The identification rate of single-phase grounding fault is further reduced due to a large number of grid-connected distributed power supply, as well as short distribution network lines and many branches.
