Along with the rapid development of related technologies such as the Internet, digital twinning, artificial intelligence and the like, digitization becomes an important task for transformation and upgrading of a central enterprise in China. The method is also suitable for the national power grid, and in recent years, along with the promotion of related technology of the "meta universe", a manager is enabled to successfully put the power grid into a computer, the computer is arranged on the power grid, and the intelligent transformation speed of the power grid is rapidly improved. The meta universe is a digital world which is parallel to the real world and is manufactured by people through computers. The meta universe is a virtual world which is generated based on the internet, is communicated with the real world and exists in parallel, and is a virtual mirror space which can be mapped to the real world and is independent of the real world.
An important technical support in the meta-universe is a three-dimensional visualization technology, and for the three-dimensional visualization technology, a powerful three-dimensional design platform is important, the rendering efficiency of the traditional three-dimensional design platform at the present stage is low, the equipment compatibility still has a problem, the three-dimensional content is manufactured by an engine-level programmer, the learning cost is high, the development difficulty is high, and meanwhile, a design development tool aiming at the three-dimensional scene is absent in a workflow, so that the application requirement of a company on building a novel power system can not be met far.
Therefore, a set of three-dimensional scene development application platform based on the WebGL architecture is designed and built, and a simple, easy-to-use and interface-friendly low-code application development function is provided for a developer. On the basis of a platform, the mirror image of the physical power grid system in the digital space can be established by a digital twin technology based on a sensor, a global ID, GIS information, a knowledge graph and the like. The mirror image system is composed of one or more electric power three-dimensional scenes, is identical to real physical system information, is continuously updated along with the change of a physical power grid, can realize comprehensive perception and prediction of the physical power grid based on a digital twin power grid, and provides key technical support for improving accuracy and instantaneity of scheduling operation decisions of the power grid.
Coming in the "meta-universe" era, many companies have also issued respective three-dimensional design platforms for three-dimensional application development parts, which also possess respective features and barriers.
1、DataV

The DataV aims at enabling more people to see the charm of data visualization, helping non-professional engineers to easily build the visualization application of the professional level through a graphical interface, and meeting the display requirements of various businesses such as conference exhibition, business monitoring, risk early warning, geographic information analysis and the like.
2、RayDataWeb

3. View of the figure TM Application editor
View of the figure TM The application editor is a special product which is based on a B/S architecture, surrounds a digital twin full-element scene and helps a user to quickly construct a professional digital twin application. The native compatible cloud-on-cloud-off multi-source heterogeneous data has rich visual components, convenient configuration management tools, comprehensive definable object attributes, extraordinary real-time rendering effects, supports functions of secondary development, deployment and release and the like, and can be widely applied to the construction of digital twin application of each subdivision industry.
Digital twin is used as a key technology for promoting the digital construction of the power grid and an important measure for digital transformation of the national network, and is concerned by the national network and companies at all levels. Digital twin technology, while bringing convenience to three-dimensional application of electric power, gradually exposes many problems, mainly expressed in the following aspects:
(1) High construction cost and low reusability. In the construction process of the traditional electric three-dimensional scene, a great deal of labor and financial cost is often required, the three-dimensional scene after construction is limited by a three-dimensional rendering engine and a technical path, multiplexing is often difficult to realize, a great deal of resource waste is caused, and the construction of a novel electric power system is very unfavorable.
(2) The operation and maintenance complexity is high, and the cost is increased. The development and maintenance of the three-dimensional application have higher requirements on the professional level, and are not matched with the technical profession of the company, and the later maintenance of various built electric three-dimensional applications is easily bound by developers, so that the operation and maintenance cost of the system is greatly increased.
(3) Three-dimensional heavy-duty application and cross-platform difficulty. The three-dimensional rendering engines used for most of the traditional built power three-dimensional scenes are Unity3D and UE4, and the two engines have very strong three-dimensional expression capacity, but the problems of large volume of the three-dimensional scenes, high configuration requirements on display terminals and the like are brought, and generally, the three-dimensional rendering engines can only be applied to PC hosts with good performance, and cross-platform access is difficult to realize.
(4) The informatization systems are difficult to fuse, the traditional three-dimensional application development is limited by a rendering engine, and the manufactured application is relatively independent and cannot be fused with other informatization systems well.
In summary, with the development and application of the digital twin technology, the construction of the three-dimensional scene of electric power is not only to simply restore the physical power grid in the three-dimensional space, but also to have comprehensive perception and prediction of the physical power grid, and meanwhile, to meet the requirements of usability, reusability, maintainability, cross-platform application and the like.
Therefore, a digital twin-based power three-dimensional scene construction method is proposed for solving the problems mentioned in the background above.
