As a key link in converting electrical energy in the high-voltage transmission network into low-voltage electrical ener-gy for users,substation is an important guarantee for the safe,stable,and reliable operation of the power system.Therefore,a three-dimensional(3D)modeling method for substations based on digital twin technology is proposed.The digital twin tech-nology system corsists of data protection layer,model computing layer,digital twin function layer and immersive experience layer.The system collects substation data information and preprocess them,and applies the preprocessed data to the 3D reality model of the substation.The substation terrain model is established through aggregation,unused lines are deleted through pro-jection to obtain an orthographic map,a 3D scene model of the substation is established,and a multi tree mixed index is used to establish a scene tree for display.The substation can be visualized in a 3D manner.The simulation experimental results show that the proposed method can not only effectively reduce the visualization display time,but also obtain more satisfactory 3D re-alistic modeling results.
