Overhaul and operation maintenance device and method for intelligent substation process layer

The invention relates to an overhaul and operation maintenance device and method for an intelligent substation process layer. By means of the overhaul and operation maintenance device and method for the intelligent substation process layer, operation maintenance personnel can be automatically reminded to adjust other affected and related intelligent devices after the operation maintenance personnel modify related input and/or data sets in capability description files of intelligent equipment. The device comprises a signal input end, a signal output end, a processor and a terminal display device, and an SCD program file for reminding the operation maintenance personnel to detect or adjust the operation parameters of the related other devices affected by the modification after configuration files of the equipment are modified due to overhaul and operation maintenance is established in the processor. By means of the device and the method, after the operation maintenance personnel modify the related input and/or data sets, the operation maintenance personnel can quickly and accurately detect and adjust the corresponding affected and related other intelligent devices, the working efficiency of the operation maintenance personnel can be greatly improved, the rate of the detection neglect and the measurement neglect can be lowered to the maximum, and the safety operation of the intelligent equipment in a substation is ensured.
