An information integrated scheme consisting of the fault circuit indicator（FCI）with synchronization measurement function，local information merge and control unit（LIMCU）and distribution automation system（DAS）is proposed.The wide area measurement and control technology is applied in the distribution network.The functional characteristics and program flow chart of the novel FCI are described.The functional characteristics of LIMCU and the communication style between LIMCU and FCI are briefly treated.Conventional monitoring function improved methods using FCI and LIMCU are proposed.New diagnosing methods involve phase to phase short circuit，inrush current，shock loading，automatic reclosing，open-conductor，transmission line standby.The new methods of locating single phase to ground fault section through the LIMCU to analyze the transient electric information and estimate the fault direction is also proposed.The research results show that the information integrated scheme can realize local diagnosis of fault and the abnormal operation states of the distribution network.The scheme can appreciably enhance the local data processing ability and information interaction ability of the distribution automation system.
