On Fault Line Detection in Neutral Grounding System via Arc-suppression Coil Based on Fuzzy Theory
To overcome the limitations and the shortcomings of the existing single fault line detection algorithm in the neutral grounding system via arc-suppression coil (NES), a novel detection algorithm is outlined. After the respective analysis of the fault component criterion, the wavelet criterion, the active power criterion and the spectrum analysis criterion, the fuzzy theory is introduced and applied in the fault line detection to intelligently integrate all of the criteria on the single-phase-to-ground fault detection and fuse all of the fault information. The simulation results show that the proposed algorithm has high reliability.
