Description

Technical Field

[0001] This application relates to the field of power grid communication, and more specifically, to a distribution network integrated service access system based on 5G cloud adaptation. Background Technology

[0002] As a typical representative of vertical industries, smart grids pose new challenges to communication networks. The diverse business scenarios and differentiated needs of different scenarios in smart grid applications present varying requirements for communication technology indicators. The diversity of grid services necessitates a flexible, programmable, and flexibly dispatchable network; high reliability requires isolated networks; and millisecond-level ultra-low latency networks are essential. 5G networks can not only perfectly inherit existing information collection services supported by 2G / 3G / 4G public networks, enabling multi-slice hybrid networking, unified management, and unified operation and maintenance within the grid, effectively helping grid customers save costs, but also support entirely new grid industrial control services. 5G reconfigurable technology can construct multiple virtual networks based on the physical layer of a single 5G network. This allows for on-demand customization, automatic activation, SLA guarantees, and secure isolation.

[0003] The challenge of 5G smart grids lies in further quantifying the network's technical specifications and the hierarchical architecture design of computing resources to meet the technical requirements of the power industry. This includes further quantifying the requirements for integrated business communication capabilities, business isolation requirements, end-to-end business latency requirements, network scalability requirements, and customized network management interfaces, in order to provide complete solutions that meet the diverse needs of the power industry across multiple scenarios.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] The technical objective of this invention is to design a distribution network integrated service access system based on 5G cloud adaptation. The smart grid is built on the foundation of an integrated, high-speed, two-way communication network. Through the application of multi-dimensional sensing and measurement technologies, advanced automation equipment technologies, advanced intelligent control methods, and advanced intelligent decision support system technologies, a new generation of power system is formed, which has the characteristics of high informatization, automation, interactivity, and intelligence. 5G offers a wealth of applications in the power industry, particularly in smart grid systems. These include: 5G-supported grid communication enables differential protection, significantly reducing power restoration time during distribution network faults and achieving true "zero-perception" of power outages; in unmanned inspection fields such as drones and robots, mobile and portable patrol deployments are possible, with 5G's high bandwidth supporting real-time transmission of ultra-high-definition inspection images to the main station. Real-time monitoring communication using intelligent robots can replace manual entry into substations, reducing risks and improving efficiency; 5G's massive connectivity allows for the deployment of numerous sensors and the collection of data from smart power meter terminals, enabling a complete process from fault monitoring and location to precise load control. Distribution network protection and control, as well as micro-synchronous phasor measurement in smart distribution networks, both require ultra-low latency communication; 5G's virtualization, customization, and slicing network technologies provide differentiated and isolated end-to-end grid communication guarantees; and with 5G support, the grid's rapid response capability to natural disasters and power outages can be fully guaranteed, enhancing its intelligence level and adaptability to innovative services.
