The invention relates to the technical field of automatic modeling of a
transformer substation centralized
monitoring system, and provides a meta-model-based centralized control
station model management method and
system, and the method comprises the steps: abstracting a new meta-model for an actual physical object, and generating a
model modification file based on the new meta-model and a historical meta-model; loading the
model modification file, converting information of a new meta-model in the
model modification file into a corresponding
sql statement, and creating a corresponding new meta-model in the meta-model
library; executing an effective operation on the new meta-model in the meta-model
library, forming a
system model based on the effective new meta-model and the historical meta-model, and setting a version of the
system model; exporting a meta-model file of the
system model, and releasing the
system model based on the meta-model file; and upgrading the meta-model
library of the historical version to the latest version based on the newly published
system model and taking effect in real time. According to the method, the new meta-model can be automatically created, smooth upgrading of the old version model is realized, the working efficiency is improved, and the error probability is reduced.
