Fault line selection based on improved grey relation analysis of zero-sequence transient current in small current grounding system

2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011
Analysis of the existing methods for fault line selection and the characteristics of zero-sequence transient current in small current grounding system, a novel fault line selection method based on grey relation analysis is proposed. The difference between fault line and normal lines is distinguished by the relation degree of the zero-sequence transient

Detection of the faulted network element using frequency spectrum features of zero-sequence current under transient earth faults in the network with neutral grounding through Peterson-coil

2016 Third International Conference on Electrical, Electronics, Computer Engineering and their Applications (EECEA), 2016
The paper analyzes the amplitude-frequency spectra of zero-sequence current in the network with neutral grounding through Peterson-coil under transient earth faults. As the assumed equivalent circuit contains elements with linear current-voltage characteristic, harmonic components of the spectrum are calculated separately for discharge current of the ...

Zero sequence currents in AC lines caused by transients in adjacent DC line

IEEE Transactions on Power Delivery, 1988
The cause of large zero-sequence transients in AC lines caused by transients in a neighbouring earth-return DC circuit is discussed. Both a qualitative reasoning and a quantitative parametric study are provided. The results show that very large transients can occur even for lines relatively far apart.

Faulty feeder selection simulation based on transient zero sequence current in non-solidly grounded network

2006 China International Conference on Electricity Distribution (CICED 2006), 2006
A simulation model of non-solidly grounded system with arc procedure is presented in the paper. Simulating calculation and analysis on different fault conditions is carried out totally by using electromagnetic transient program (EMTP). By deeply analyzing the simulation data and waveform, we get the following conclusions: detection method based on ...
