description: The graduation thesis topic is âStudy of arcing faults in overhead lines using mathematical model of an open-flame arcâ.
The work is dedicated to determination of open-flame arc self-quenching conditions in the event of a single phase-to-ground fault in 35 kV overhead distribution networks with low fault current in case of different neutral grounding modes. The challenges addressed in this paper are:
1. Observation of the existing conventional arc models and assessment of their conformance to the theoretical studies constraints.
2. Calculation of single phase-to-ground arcing faults in 35 kV distribution network with various grounding modes.
3. Analysis of the arc self-quenching conditions and correlation of the obtained results with the common hypotheses, devoted to determining both conditions of single phase-to-ground faults extinction in overhead lines, and mechanisms of overvoltage establishing.
The arc gap simulation based on the mathematical channel model of the cylindrically symmetrical upright arc stabilized by rising convective gas flow was carried out in ATPDraw software program.
Application of the universal arc model, which does not depend on the experimental data, proved the possibility of low-current arcs self-quenching in 35 kV distribution networks. Hence, there is no reason in locating the fault. The suggested methodology allows to analyze self-quenching conditions of the arcs occurring during transient single phase-to-ground faults, thus assessing the network reliability.
