Abstract
Digital twins refer to virtual digital expressions constructed in virtual space that can characterize characteristics, the formation process and behavior of natural entities, and it has the characteristics of multi-physics, multi-scale and probability. This article mainly introduces the application research of digital 3D twin panorama modeling in power distribution network. This paper proposes the average current method to calculate the line loss of the power distribution network, so that the accuracy is guaranteed. In addition, the digital three-dimensional panoramic modeling method is used to optimize the grid system, and the data structure is used to calculate the power distribution network. Analyze the topological structure of the power grid, and then obtain the calculation method of the distribution network line loss. The experimental results in this paper show that the rendering efficiency of power grid results has increased by 17% based on the digital 3D twin panorama modeling, and the method and algorithm for matching video and panorama image are proposed, which solves the problem of video rotation angle on the panorama connection, so that The smoothness of panoramic roaming is improved by 23%.
Highlights
Electric power distribution network refers to the electric energy meter that the power loss generated by the station during the operation of the power grid or the substation reaches the user during the power transmission process [1]
The theoretical line loss rate is an important basis for power supply companies to formulate reasonable line loss management indicators
Research and analysis of various calculation models show that the average current method can obtain better calculation accuracy, and the required calculation parameters are usually easy to obtain, which is more suitable for the theoretical line loss calculation needs of rural power grids
Summary
Electric power distribution network refers to the electric energy meter that the power loss generated by the station during the operation of the power grid or the substation reaches the user during the power transmission process [1]. The power loss rate is a measure of the degree of loss in the energy transfer process It fully reflects the design, design, operation and management level of the power system, and is an important economic and technical indicator of the operation of the power grid [2]. Chakshu NK proposed a method that can detect the severity of carotid artery stenosis through face video with the help of coupled blood flow and blood flow. The pulsating nature of the blood flow through the carotid artery causes subtle vibrations in the head This vibration is a potential indicator of the severity of carotid artery stenosis, and he has proposed a head vibration model that is related to the force generated by blood flow with or without obstruction. Proposed the use of ray intersection judgment and block loading processing method to accelerate the loading of panoramic images, so that the three-dimensional panoramic digital interactive exhibition platform is more smooth [9,10]
