The invention discloses a
transformer substation three-dimensional parametric modeling method and
system based on
engineering design drawings. The method comprises the following steps: standardizing and correcting a design completion drawing of the
transformer substation, and outputting a standardized drawing; the method comprises the following steps of: identifying buildings and
power grid equipment and facility components in a
transformer substation based on a standardized drawing, extracting geometric information and converting spatial positions to obtain a topological relation, converting extracted geometric parameters into information with definite constraint
semantics, and forming modeling parameters according to the obtained spatial positions, semantic attributes,
model parameters and the topological relation; and selecting a proper parameterization modeling method to carry out automatic model construction according to the modeling parameters in combination with
machine account data, equipment, implementation classification and a predefined model component
library. According to the method, the automatic construction technology of the parameterized model is researched by focusing on
pattern recognition and semantic and topology extraction, 'associated automatic generation 'of the three-dimensional model of the transformer substation from zero to integer is realized, and the method has low-cost whole-
station modeling capability.
