Abstract The problem of single line to ground fault doesn’t be sovled well. Single line selection method for fault characteristics and the influence of outside interference lead to dead zone and limitation. In this paper, on the basis of fuzzy theory method, the energy method which has been improved and 5 times harmonic method is combined with wavelet analysis in order to improve the fault line selection method in line accordance with the complementary of each other. Through simulation and experiment, The method is suitable for the small Angle ground fault, high resistance grounding fault, line-terminal fault, arc grounding fault and unfavorable to achieve the fault line selection. the proposed method has better accuracy and applicability.

Key words： single line to ground fault fault line selection fuzzy theroy CEEMDAN
