Abstract: A new method of fault-line selection for mine power network based on information fusion technology was presented.The method was immune from the condition whether arc-suppression coil existed or nor.It improved the accuracy of lineselection by selecting the stable,singular and transient characteristics of fault as fault feature vectors,employing the D-S evidence theory to transform three fault vectors to criterions,using the iterative algorithm to fusion the criterions which made line-selection result focusing on a common ground of the criterions.The method has good versatility and is especially suite for mine power network.The simulation verified the effectiveness of the proposed method.
