Single-phase grounding fault identification and fault line selection for compensation grid
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012A 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 ...

A fault location method for single-phase grounding fault in distribution network
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015The single-phase grounding fault is the most common fault among all types of faults in distribution network. It is of great importance to locate the single phase grounding fault accurately and quickly for reducing economic losses. Aiming at the location of single-phase grounding fault in distribution network, this paper puts forward a new fault ...

Transient processes at single phase-to-ground faults in combined grounded networks
2012 Electric Power Quality and Supply Reliability, 2012This paper deals with the combined method of neutral grounding when a high-value resistor is continuously connected to a neutral in parallel with a Petersen coil. Monitoring of processes at single phase-to-ground faults was organized in the 6 kV network of the large-scale iron and steel plant.

IEEE Transactions on Instrumentation and Measurement
Distribution system structures are intricate and variable, with single-phase ground (SPG) fault occurring frequently. Existing section location methods for SPG faults are often influenced by manually set thresholds, resulting in low accuracy.

IEEE Transactions on Power Delivery, 2022
The single-phase to ground fault (SPGF) is very common in power grids. To decrease the fault’s influence on the power supply’s reliability, the neutral point is usually grounded via the Petersen coil, significantly reducing the outage rate. Nevertheless,

Single-Phase Ground Fault Location of Distribution Network with DG Based on CEEMD
2020 Asia Energy and Electrical Engineering Symposium (AEEES), 2020When a single-phase ground fault occurs in the resonant grounding system, the arc suppression coil only compensates for the power frequency zero sequence current, but has little effect on the non-power frequency zero sequence current.
