PROBLEM TO BE SOLVED: To more appropriately support recovery from multiple accidents in overhead transmission lines.SOLUTION: An accident recovery support system 1 includes an accident recovery support device 2 comprising an information acquisition unit 121, multiple accidents determination unit 122, system priority setting unit 123, and recovery priority setting unit 125. The information acquisition unit 121 acquires accident occurrence system information for identifying a transmission system in which an accident is occurring. The multiple accidents determination unit 122 determines whether or not multiple accidents are occurring in transmission systems, on the basis of the accident occurrence system information. The system priority setting unit 123 refers to a system significance database to set system priority to each transmission system identified using the accident occurrence system information, when the multiple accidents determination unit 122 determines that multiple accidents are occurring.
