The Application Of Gis Technology In Vehicle’s Scheduling System For Emergency Repairs Of Power Supply

As the electric power industry development, continue to expand the scale of power grid, the electric grid structure increasingly complex, urban and rural power distribution network fault appears the absolute number of also sharp increase, how to guarantee the fault in the fast repair power supply system, and improve the power supply enterprise to repair the response speed of the power failure is imminent. Improve the response speed of the basic guarantee is repair vehicles and personnel quickly arrive at the scene of the time, this requires power repair vehicles in all-weather controlled condition and can quickly science scheduling. Most current regional power supply enterprise to repair vehicle just monitoring and positioning, to prevent speeding and illegal parking wait for a phenomenon, and no scientific scheduling system support.This article in view of the regional power supply enterprise to repair vehicle management demand, the first to the GIS and repair dispatch vehicles management of related techniques analysed deeply research, according to the actual power supply emergency repair scheduling of business process, the construction based on GIS technology power repair vehicle rapid prototype system scheduling platform. The system mainly including four core function module:vehicle monitoring module, work order management module, rapid scheduling module and system management module. Vehicle monitoring module implements in the repair process to repair vehicle process monitoring and repairs after completing the track playback; Work orders management module implements repair process of issued and input single zhonggong query and after completion of repair work order statistics; Rapid scheduling module implements repair fault point in quick location and fault priority determination, and calculating optimal path fast scheduling repair vehicles; System management module implements user permissions, vehicles, the unity of the information management.In the vehicle scheduling optimal path selection in a network model and Dijkstra algorithm, in operation in the trial can achieve to repair vehicle location monitoring tracking, history inquiry on basic functions, priority strategy achieved coordination concurrent malfunction repair scheduling, greatly enhancing the fault of the time for repair.
