Digital twinning system of power plant

The invention provides a power plant digital twinning system, which comprises a three-dimensional scene layer used for performing forward three-dimensional design and reverse three-dimensional design on a power plant to construct a digital power plant; the digital twinning implementation layer is used for performing three-dimensional element extraction on a digital power plant, establishing a mapping relationship between three-dimensional elements and power plant identification system codes, performing logical relationship configuration on the three-dimensional elements for establishing the mapping relationship, and coupling the three-dimensional elements and power plant multi-source data according to the mapping relationship and the logical relationship to obtain a coupled power plant identification system; constructing a digital twin power plant; and the display layer is in interactive connection with the digital twinning implementation layer, and the display layer is used for rendering and displaying the d
