| Abstract: | On the basis of analysis on the characteristics of single phase grounding fault occurred in small current neutral grounding system, combined with the characteristics of wavelet transformation and fuzzy neural network, a wavelet fuzzy neural network method and algorithm was proposed and applied for the fault location on non-direct grounding system, which is suitable for the analysis of the post-fault transient state signals in power networks. Theoretical analysis and the simulation results illustrate the efficiency and practice of the method proposed. |
