In January 2023, the “Several Opinions on Accelerating the Development of Digital and Intelligent Energy” issued by the National Energy Administration mentioned that digital and intelligent power grids support the construction of new power systems.

Youli digital twin technology enables the construction of new power grids

Through the three-dimensional engine technology certified by Xinchuang, Youlitech can load super-large three-dimensional data in seconds, upgrade the power grid system from the bottom. Based on the unique three-dimensional data management engine of Youlitech, from data collection, modeling to application, realize the digital twin of the power grid, such as transmission, power transformation, distribution of three-dimensional analysis, three-dimensional inspection, training, etc., while supporting the multi-terminal auxiliary business development. Let digital, intelligent will become the daily power grid.

High precision 3D point cloud modeling service

The world’s leading stand laser scanner is used to collect ultra-high precision laser point cloud data of all substation stations. The whole station model can reach millimeter level accuracy, point density reaches 200,000 points/square meter, the average error is within 2MM, and the maximum error is no more than 6MM. The ultra-high precision laser point cloud data of Youli comprehensively surpasses the three aspects of restoration degree, aesthetics and practicality. High-precision scanning can effectively reduce the human and property loss of repeated scanning.

3D asset management cloud platform

Based on the excellent rendering technology, without relying on high-configuration hardware, it supports the online second-level loading of massive and high-precision 3D data on the computer and mobile terminals, opening up the entrance of the digital 3D world on the mobile terminals, and the processing, storage, rendering and application of massive 3D data are all in one platform.

3D power grid map is a software system based on 3D point cloud data management, data analysis, working condition simulation and UAV track planning assistance.

Based on real 3D information of simulated 3D earth and point cloud, it can realize functions such as high-precision data measurement, area, volume calculation and analysis, tree vegetation analysis, environmental trend analysis, intelligent channel management and control. Based on high-precision location and shape information of target objects, track planning, track verification and optimization of UAV autonomous flight are carried out in a three-dimensional environment to avoid on-site risks. Provide perfect 3D data display and management analysis solutions for customers in various fields such as power and energy.

Mobile power grid management system

By using Youli infinite detail rendering technology, the mobile terminal can quickly and remotely load the three-dimensional data of the power grid, realize the mobile process of “operation and inspection business management” and “professional technical control”, and facilitate the work of staff in the station. Realize the mobile information query of “panoramic video surveillance”, “Multi-dimensional information presentation”, “equipment status analysis”, “equipment disposal strategy”, “equipment asset management” and “knowledge and skills training” applications, providing convenience for carrying out mobile operations.

Simulation substation training system

As a global leader in tracking holographic equipment, Youliyi provides 3D training software customization services based on holographic equipment. Because Youliyi has its own “infinite detail engine”, it can realize the production of training software in ultra-large scale and fine scenes, and can apply ultra-precision laser point cloud data to training scenes to achieve real and virtual environments that other engines cannot achieve.
