Single-phase grounding fault identification and fault line selection for compensation grid

Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012
A new grounding fault line selection method based on small-world network theory is proposed in order to solve the problems existing in grounding fault line selection device of compensation grid, such as that the correct rate of grounding fault line selection is not high and the selection device cannot recognize high-impedance and low-impedance ...

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 ...

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.

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.
