The invention discloses an information processing method and an information processing system in a substation transformation process. The information processing method comprises the following steps that after the original ICD (IED Capability Description) document of target power equipment is modified, the obtained original ICD document of the target power equipment is compared with the modified ICD, first modified information which is modified previously in the modified ICD is confirmed, and then, the modification part in the modified ICD is directly imported into the corresponding part of an original SCD (Substation Configuration Description) document without importing the non-modified part, so that the problems of the increase of difficulty and workload of the field adjustment work, the reduction of efficiency of the field adjustment work and influence on the working efficiency of the substation transformation works as in the substation transformation process, when the original ICD document of the target power equipment needs to be modified a plurality of times, the corresponding part of the original SCD document is replaced with the modified ICD document a plurality of times and the original configuration of the target power equipment is correspondingly adjusted according to the ICD document modified each time in the prior art can be solved.
