The embodiment of the invention provides a storage method and apparatus of power grid fault data. The storage method of power grid fault data includes the steps: acquiring the power grid fault information through a bus interface of an intelligent scheduling control system, and acquiring the equipment ID and the fault occurrence time of fault equipment from the power grid fault information; according to the equipment ID and the fault occurrence time, acquiring the original fault data of the preset time quantum on the intelligent scheduling control system; and according to the original fault data, according to the preset filtering principles, determining the fault data text to be stored. The storage method and apparatus of power grid fault data can screen the power grid fault data related with the fault from the mass power grid data, can intensively and standardizedly storage the data, and can improve the transplantability of the fault data.
