Power transmission line management system based on digital twinning

Abstract

The invention relates to a power transmission line management system based on digital twinning. The power transmission line management system comprises a digital base plate layer, a data sensing module, a background service center, a local processing center and a display layer, through processing of a multi-system data fusion algorithm of autonomous learning, facilities and equipment such as a power transmission line and a transformer substation are subjected to three-dimensional model establishment, data are interconnected with data of various subsystems, real-time interaction and accurate correspondence of the data are realized on a constructed digital twin platform, management of multiple application systems on a unified'graph 'is realized, and the management efficiency is improved. The system has the advantages that the system is simple in structure and convenient to use, accurate position service is provided for fault warning, inspection personnel and the like, quick response and timely, scientific and reasonable disposal for possible faults and accidents are achieved through data interaction and cooperation of multiple systems, and powerful platform support is provided for safety monitoring, line inspection and other work.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a digital twin-based power transmission line management system. Background technique [0002] In the process of power transmission, transmission lines and substations are one of the keys to ensure the safety of power transmission. The daily management of transmission lines involves multiple modules, such as high-voltage line management information system, data acquisition and supervisory control system (SCADA) system, lightning protection positioning , video research and judgment system, etc., monitoring system, but most of the information between each module is independent, the data is difficult to share, and it is difficult for each subsystem to be effectively combined with the real scene, and it cannot be used for the management or inspection of transmission lines. to a good auxiliary role. [0003] Digital twin is a simulation process that makes full use of physical models,...

[0002] In the process of power transmission, transmission lines and substations are one of the keys to ensure the safety of power transmission. The daily management of transmission lines involves multiple modules, such as high-voltage line management information system, data acquisition and supervisory control system (SCADA) system, lightning protection positioning , video research and judgment system, etc., monitoring system, but most of the information between each module is independent, the data is difficult to share, and it is difficult for each subsystem to be effectively combined with the real scene, and it cannot be used for the management or inspection of transmission lines. good support

[0003] Digital twin is a simulation process that makes full use of physical models, sensor updates, operation history, etc., integrates multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and completes the mapping in the virtual space to reflect the entire life cycle of the corresponding physical equipment. process; the monitoring system of transmission lines and transformer stations. The traditional monitoring display is mainly based on two-dimensional views. The displayed data are independent of each other, so it is difficult to share and interact, and it is not convenient to display the information of each site in practice. And when an accident occurs, it cannot be accurately compared with the actual location, which is not convenient for rapid positioning when a fault occurs
