Background
The stable operation of the power system is not separated from the good operation of the power equipment, the maintenance and the technical transformation of the power equipment are indispensable, but the transformation of the transformer substation is a trivial and complicated work. At present, a substation technical improvement project is not standardized by a unified typical design, and a designer often designs according to personal experience only. Particularly, some technical improvement projects relate to matching of various devices, new devices need to be selected and checked, and if the design is made only by personal experience of a designer, errors often occur, so that the on-site construction is delayed. Even if some simple transformation is performed, only one or a few devices are possibly replaced, the designer is required to repeatedly check and verify, so that waste of manpower, material resources and financial resources is caused, and when similar transformer substation technical transformation projects are designed by different designers, the quantity of auxiliary materials (such as voltage power cables, fire-retardant bags, plugging materials and the like) required in transformation is greatly different because of different equipment types or different personal experiences, so that engineering quantity and manufacturing cost are also far different. In a word, if the engineering is finished by pure manpower, the working efficiency is low, the error rate is high, the power transmission time is easily delayed, and the power utilization of a user is influenced.
Furthermore, simulation software is introduced to simulate in the prior art, the Revit software is a common tool for building model modeling, and the Unity3D is a domestic popular model display engine supporting cross-platform.

In order to solve the above problems, the existing worker introduces the building information model into 3DMax, performs secondary mapping, and then exports the building information model to Unity3D for display, but this method requires a specialized 3DMax engineer in converting the building information model, so the labor cost is high.
