Hierarchical modeling method for secondary circuit of transformer substation

The invention provides a hierarchical modeling method for a secondary circuit of a transformer substation, and the method comprises the steps: determining a plurality of different layers for modeling the secondary circuit of the transformer substation, and the plurality of different modeling layers comprise a transformer substation layer, a screen cabinet layer and an equipment layer; and determining each level modeling object of the secondary circuit of the transformer substation. Modeling content of the modeling object is determined. A modeling language and a modeling tool are determined. And determining a description file of each level of the secondary circuit of the transformer substation according to the modeling content of the modeling object by adopting a modeling language and a modeling tool. According to the technical scheme, the digitization level of the design result file is effectively improved, the construction, debugging, operation and maintenance efficiency of the secondary circuit of the trans
