Modeling and simulation analysis of single phase arc grounding fault based on MATLAB

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
The single phase arc grounding fault is a main fault form in medium voltage distribution networks. It is essential to build an accurate grounding arc model for fault analysis. In this paper, a new grounding arc model is built based on the MATLAB with the arc gap energy-balance theory.

Fault line Selection of Single Phase Grounding Fault in Small-Current Ground System Based on Reactive Current

2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2019
It is difficult to select fault line accurate when single phase grounding faults occur in small-current ground system. The manuscript proposed a novel fault line selection scheme base on reactive current. According to theoretical analysis, the variation of current after the occurrence of single phase short circuit is mainly composed of capacitive ...

Single phase to ground fault location based on phase of zero-sequence current

2013 IEEE International Conference on Information and Automation (ICIA), 2013
With the continuous development of society and the improvement of people's life, people are increasingly concerning about the safe operation of the power grid, and single phase to ground fault of distribution networks is one of the problems. Because more branch of distribution networks and complex structure, the traditional methods can't achieve ...

A New Fault Location Algorithm for Single Phase to Ground Faults in Power Distribution Network

2010 International Conference on Measuring Technology and Mechatronics Automation, 2010
A new fault location algorithm for distribution network is proposed based on the wide-area synchronizing information. The algorithm is based on the distributed parameters model in the small current neutral grounding system, and constructed a fault location function according to the relationships between the fault current and fault distance, which fully

Recognition of the Single-Phase Ground Fault in Power Distribution System

Key Engineering Materials, 2011
For power distribution systems, recognizing the single-phase ground fault is very difficult because there are several faults with similar features. This paper presents a novel method that can help to overcome this difficulty. The idea is to turns the original fault info into a whole system with transient state, steady state and transition state ...

Transient based Single Phase to Ground Fault Distance Computation

2009
The subject of this work is location of single phase to ground fault in medium voltage distribution network. The considered distribution network can be grounded or isolated and normally is in radial operation. The fault location is based on the fault generated low frequency transient signals of current and voltage of faulty phase measured in the supply
