Intelligent substation three-dimensional modeling, based on the three-dimensional model to achieve converter station maintenance, three-dimensional intelligent inspection……

The use of three-dimensional laser point cloud acquisition, digital elevation model, high-precision mapping and other technologies, for each line, each base tower, each component is given a unique three-dimensional coordinate, positioning accuracy reaches centimeter or even millimeter level, it is the power industry through the digital twin to build the real world and the digital virtual world bridge.

In the process of digital twins constantly being seen by the industry, the ideal digital twin of Uli technology is to realize remote collaborative work between people and the same remote control of the scene and the scene, and the realization of these operations only requires a mobile phone or a PC.

Intelligent inspection, algorithm first

A 50MW substation manual inspection complete a circle, covering all equipment takes 2-3 months, and machine inspection only takes about 2 days.

Under the need of a new generation of substation centralized monitoring system and remote intelligent inspection system to replace manual routine inspection, lights out inspection and some special inspection, accelerating the construction and application of substation intelligent inspection and expanding the coverage of substation intelligent inspection has long become one of the scenarios where the digital twin technology sinks to practical application.

Excellent three-dimensional intelligent inspection system

At present, based on the power industry data mined in massive data, Youli Technology has reached more than 10 cases in the power field, and its application has gradually become shallow.

“In the past, people would think that the digital twin can build a visual system of the substation by establishing a dynamic digital substation dynamic model, connecting it to the model according to the actual installation position of the camera signal?”

Zhang Xuebing, founder and CEO of Youli Technology, explained that in the past, the industry did do a lot of “good-looking” attempts in the digital twin project, mostly artificial modeling, in addition to high data repair investment, the “one picture” made can only run on the workstation, appear on the large screen, can not be accessed with mobile phones or browsers, and is farther and farther away from the user.

When more and more customers, especially enterprise and government users, are not willing to spend large costs on the “flower shelf” prepared for inspection, the real 3D application enterprises represented by Youli Technology are therefore eye-catching in practical applications.

Compared with the original so-called “intelligent inspection”, what changes have happened to the real digital twin technology in actual power applications?

Zhang Xuebing said, “In the space of digital twins, we first do a basic calculation, that is, according to the corresponding specifications and standards list of equipment inspection points in the field of power grid, to measure whether the cameras currently deployed by power grid and other units have met the inspection needs of enterprises for all equipment inspection points.” After all, some of the equipment is installed very high, some are six meters high, and some are even ten meters high, which has formed a large three-dimensional space.”

The coverage of cameras in the power field in various provinces is generally difficult to exceed 70% : in the past, the deployment of cameras was achieved by camera manufacturers according to experience and on-site surveys.

The intelligent inspection camera point optimization service of Youli Technology provides relatively cost-effective coverage solutions for customers in the power field through intelligent algorithms in three-dimensional space. “Is the installed location the location that the user needs to be inspected, and what places have not been covered, how to add?” If not, where should it be installed?”
