Fault Line Selection Method Considering Grounding Fault Angle for Distribution Network

Journal of Northeast Agricultural University (English Edition), 2015
Abstract In the distribution network system with its neutral point grounding via arc suppression coil, when single-phase grounding fault occurred near zero-crossing point of the phase voltage, the inaccuracy of the line selection always existed in existing methods.

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.

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 ...
