The invention discloses a substation equipment maintenance method and belongs to the technical field of electric system. The method comprises the steps: acquiring operation information of substation equipment, determining problem information according to the operation information, determining a maintainer and maintenance information according to the problem information and a pre-established substation equipment maintenance topological graph, and transmitting the maintenance information to the maintainer who can maintain the substation equipment according to the maintenance information. According to the invention, acquiring, processing and feedback of the operation information, the problem information and the maintenance information can be comprehensively utilized, the maintainer and the maintenance information can be determined according to the problem information and the pre-established substation equipment maintenance topological graph, the maintenance information is transmitted to the maintainer, so that the maintainer can maintain the substation equipment according to the maintenance information, and the accuracy of the maintenance information can be improved. In addition, maintenance cycle of the substation equipment can be adjusted according to the maintenance information, the maintenance cycle of the substation equipment can be corrected, and the maintenance cycle is close to the current maintenance request of the substation equipment.
