精准负荷控制在电力5G环境中的应用

Application of 5G in Precise Load Control of Power System

精准负荷控制属于电网生产大区业务,要求和其他管理大区业务完全隔离。毫秒级精准负荷控制对通信网络的关键需求是毫秒级的超低时延,5G技术具有低时延、高可靠性的特点,理论上能够满足精准负荷控制的要求。基于此,研究5G的网络切片技术和低时延技术,并且基于5G技术,对负荷控制业务进行了分析和研究,结果表明5G技术能满足负荷控制业务对端到端通道50 ms的时延要求,取代光纤通信进行负荷终端之间实时通信。在实验室搭建源网荷毫秒级控制业务测试网络,初步完成负控业务基于5G环境的可行性测试,并与基于4G环境下的测试进行了对比,测试时延能够满足控制业务的要求。研究结果可为基于5G网络的电力业务应用拓展提供参考,为其他电力业务在5G场景下的应用奠定理论基础。

Precise load control belongs to the business of power grid production region,which requires complete isolation from other management regions.The key requirement of millisecond level precise load control for communication network is millisecond level ultra⁃low delay.5G technology has the characteristics of low delay and high reliability,which can meet the requirements of precise load control in theory.The 5G network slicing technology and low delay technology were studied,and the load control service based on 5G technology was analyzed and studied.The results show that 5G technology can meet the demand of end⁃to⁃end channel 50 ms delay for load control service,and replace optical fiber communication for real⁃time communication between load terminals.The source network load millisecond level control service test network was built in the laboratory,and the feasibility test of load control service based on 5G environment was preliminarily completed,and compared with the test based on 4G environment,the test delay could meet the requirements of control service.The research provides a reference for the application expansion of power service based on 5G networks,and lays a theoretical foundation for the application of other power services under 5G environment.
