摘要(Abstract):
5G通信技术具有大带宽、低时延、高可靠性、服务化网络架构等优势,被认为是解决智能电网、智能交通、工业4.0等控制类应用场景通信需求的新型无线通信技术。从配电网精准控制保护业务底层原理出发,通过分析保护装置差动电流触发故障隔离控制指令机制、保护业务规约报文与传输模式、装置热稳定性等,精确定义配电网差动保护业务通信模式、传输带宽、接收时延、时间同步和网络安全防护等通信需求;结合5G通信技术最新标准化进程,开展面向配电网差动保护业务端到端网络组网方案、安全认证等方面的设计,并通过承载实验验证了方案的技术可行性。
With the advantages such as large bandwidth, low delay, high reliability and service-based network architecture, 5 G is considered as a new wireless communication technology to meet the communication requirement of smart grid, intelligent transportation, Industry 4.0 and other control application scenarios. By providing insight into the fundamental principle of precise control and protection for distribution network, the paper analyzes the mechanism of fault isolation triggered by differential protection current, the communication protocol message, transmission mode and thermal stability to precisely define the requirement of the communication mode, bandwidth, delay, time synchronization, and network security protection for the distribution current differential protection. Combined with the latest standardization process of 5 G, the comprehensive design including end-to-end networking and security authentication scheme are proposed for distribution current differential protection. The technical feasibility of the proposed scheme is verified by bearing test.
