【Abstract】 To be one important method of information fusion,the D-S evidence theory apply to fault line selection in small current power system can improve its accuracy.Details about choosing different methods to dispose fault line information in different conditions and the line fault probability to be fused by the information fusion to improve its accuracy.Points out how to ameliorate the chosen methods the compare breaths and phases selection theory and the wavelet analysis,how to improve the methods to use for information fusion,and designs arithmetic to calculate the indeterminacy of the D-S evidence theory.更多还原
