Evidence theory shows special function in solving fusion problem of multi-source information and especially solving uncertainty problem.However,the authoritativeness of dynamic evidence is not analyzed in evidence theory combination rules,which will generate the deviation in the process of dynamic evidence combination,and even induce the prediction opposite to thought of humanity.For the above-mentioned deficiency,the dynamic evidence combination rules based on time conversion has been proposed.Through considering time-varying nature of evidence authoritativeness and combining time conversion function with evidence combination rules,the deviation generated in the process of dynamic evidence combination can be effectively avoided.To testify its effectiveness,the scheme was applied to the trouble detecting of main transformer in Fengman Electricity Generating Station.The test results show that the proposed method is feasible and efficacious.
