Abstract: In order to improve the ability of the operators to deal with the faults of the power grid, excavate the historical fault data deeply, and realize the historical fault inversion and artificial intelligence dispatching, the electric power dispatching needs a set of intelligent fault treatment system. With the help of the original power grid resources and technical platform such as the regulation and control cloud, the system can deal with the resources of different subsystems through integrated access to the power grid fault, to realize the functions of integrated fault diagnosis, integrated information visualization display, on-line security analysis, fault assistant decision-making and artificial intelligence dispatch, it realizes the effective use of historical fault data, enhances the artificial intelligence level of regulation and control operation, and ensures the safe, stable and reliable operation of power grid.
