The invention provides a method for power grid fault characteristic data remote sharing among scheduling control systems and belongs to the technical field of intelligent analysis and control of electric power systems. The method, based on the wide area service bus technology, proposes the interactive mode and interactive content of power grid fault characteristic data among scheduling control systems; and scheduling control operating personnel can directly retrieve power grid fault characteristic data such as split-phase switch position change, bay accident integration and protection action signals of equipment faults of other scheduling control systems via a local scheduling control system, remote sharing of power grid fault characteristic data is achieved and the power grid equipment fault online sensing ability of scheduling control operating personnel is improved.
