[0058] Combined with Figure 1 As shown, this embodiment provides a power grid fault processing system, including: a database 110, used to store an operation task set, an operation rule set, power grid configuration information and real-time operation data of each power device in the power grid; a fault diagnosis module 120, connected to the database 110, used to obtain the location information of the power grid fault according to the symptom information of the power grid fault, the power grid configuration information and the real-time operation data of each power device; an operation ticket reasoning module 130, connected to the database 110 and the fault diagnosis module 120 respectively, used to generate a dispatch instruction according to the location information of the power grid fault, the operation task set, the operation rule set and the power grid configuration information; and an operation ticket generation module 140, connected to the operation ticket reasoning module 130, used to generate an operation ticket according to the dispatch instruction to repair the power grid fault.

[0059] Specifically, in this embodiment, the operation task set stored in the database 110 may include several operation tasks, and each operation task may be preset according to the working switching mode of each power device in the power grid; since each power device includes at least two switching modes of activation and deactivation, each power device may correspond to at least two operation tasks. For example, the two operation tasks corresponding to a transformer are activation of the transformer and deactivation of the transformer; the two operation tasks corresponding to a tie switch may be changing the tie switch from operation to hot standby and changing the tie switch from hot standby to operation. The operation rule set may include several operation rules, and each operation rule may be preset according to the operation task and in combination with the power grid dispatching regulations and dispatching operation management details; the operation rule is a structured knowledge that maps the operation task to the dispatching command, and the operation rule and the operation task may correspond one to one, but the present invention is not limited thereto.

[0060] Specifically, in this embodiment, the database 110 may also be connected to an external power SCADA system so that the power SCADA system can transmit the real-time operation data of each power device to the database 110, but the present invention is not limited thereto.
