A New Fault Location Algorithm for Single Phase to Ground Faults in Power Distribution Network
2010 International Conference on Measuring Technology and Mechatronics Automation, 2010A 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, 2011For 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 ...

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, 2011The 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.

A survey on faulty line selection technology for single-phase-to-ground fault in China
2013 IEEE Industry Applications Society Annual Meeting, 2013Single-phase-to-ground fault is difficult to detect with traditional methods in NIEPS because of minor fault current, fault arc, harmonics influence and the protection principle limitation. In order to improve the precision and reliability of traditional faulty line selection technologies for NIEPS, more attention has been paid by many researchers over

Transient based Single Phase to Ground Fault Distance Computation
2009The 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
