Faulty Section Location Method Based on Dynamic Time Warping Distance in a Resonant Grounding System
Energies, 2022 When a single-phase grounding fault occurs in a resonant grounding system, the determination of the fault location remains a significant challenge due to the small fault current and the instability of the grounding arc.

MATLAB Power System Simulation of Resonant Grounding Fault
Energy Procedia, 2012 AbstractIn order to handle the situation of power system grounding fault better, this paper built the mathematical model of power system resonance grounding fault based on the resonance grounding principle. And simulated the resonance processes by using MATLAB/SIMULINK/ SIMPOWERSYSTEM (SPS) software.
