Digital twin technology has been widely disseminated and gradually applied in the fields of aircraft manufacturing, CNC machining and workshop assembly. This paper mainly aims at the problems of weak mapping ability and low precision in mapping the real scene of digital twin technology into virtual space, as well as low efficiency and difficulty of visualization in virtual space, using the powerful graphics library and rendering engine of the Threejs framework, combined with the stereoscopic vision of binocular vision. Positioning technology, using Threejs as a platform to build a visual digital twin application framework, and develop a digital twin visual decision-making system. Combined with the application scenarios of electric power intelligent emergency repairs, aiming at the urgent digital transformation problems of live working robots and robotic arms in the power grid industry, Threejs technology is used to realize the construction of digital twin electric power emergency repair robotic arms and real scenes in virtual space, combined with binocular stereo vision technology Realize the acquisition of the three-dimensional coordinates required for power emergency repairs, simulate the whole process of power emergency repairs in real time, and provide new ideas for improving power work efficiency, reducing operating costs, and ensuring personnel safety.

With the rapid growth of the communication system infrastructure of The State Grid and the rapid advancement of the digital economy in the digital era of the power grid, it has become an urgent need for the rapid development of China's energy industry to find the key technologies to realize the digitalization of the security management and network intelligence of the State grid. Digital twin technology is also leading the development of the power grid digital era. Through digital identification, intelligent sensing, data resource pooling, digital twin modeling, and other key technologies, it effectively leads the safe and stable operation of the entire power grid in China. Firstly, this paper focuses on the historical development background, connotation and characteristics of digital twin technology. Combined with digital twin technology, this paper analyzes the development status of Smart power grid and digital power grid in China, and then introduces the key technologies based on digital twin technology in the field of power grid development, as well as the typical applications of these technologies in power grid enterprises. Then it points out the technical difficulties in the construction of digital twin power grid and the challenges in the field of power grid. Finally, it provides important theoretical support for the long-term construction and development of digital twin power grid and points out the new direction of power grid development.
