Research and Simulation on the Solution of Single-Phase Arc Grounding in Distribution Network

Abstract

The paper deduces the functional relation between amplitude of recovery voltage, average rate of recovery voltage of single-phase arc grounding fault and the system parameters. Combining the theoretical results of this paper, the important role of out-of-resonance degree in decreasing the amplitude of arc grounding overvoltage and suppressing arc reignition is explored. Using MATLAB to establish an improved Mayr dynamic arc simulation model to validate correctness and reliability of the conclusions. The conclusions are instructive to the safety and economical operation of distribution network.
