Background
For a long time, when a power distribution network fails, after the failure is reported, before rush repair personnel enters a site for rush repair, failure information can only depend on the description of a user, and a failure source cannot be accurately positioned, related failure equipment information can be obtained, the failure type and the influence range can not be analyzed, and the like. For example, an existing power user performs fault repair by a repair call of a power supply company 95598 (state network power customer service system), a 95598 service acceptance person performs repair acceptance, records repair information of the user, forwards the repair information of the user to a 95598 remote workstation, the 95598 remote workstation person distributes emergency repair work orders to emergency repair classes according to repair regions, the emergency repair classes receive the emergency repair work orders and then schedule the emergency repair persons to confirm fault types on site, and then perform on-site emergency repair. What the above-mentioned present situation brings is: locate the trouble source when power failure takes place, acquire relevant trouble equipment information, analysis fault type and influence scope must be gone on by the personnel scene of salvageing, the progress of salvageing has been influenced, simultaneously because the type and the influence scope of trouble can not be made clear when the dispatch, so under the certain condition of personnel's quantity of salvageing, can not realize salvageing on personnel's preferential configuration arrives the power failure that the influence scope is big, be unfavorable for in time solving the power failure that the influence scope is big, can not realize the best configuration of salvageing the resource, and simultaneously, after the trouble takes place, salvage personnel learn the time period overlength of information, lead to maintenance efficiency low, waste a large amount of costs.
