摘要
5G技术具有超高可靠性、低时延的性能,为配电网控制保护技术的深度发展奠定了良好的通信基础。基于5G的配电网差动保护在极大提升配电网故障隔离水平的同时,也促进了5G的垂直行业应用。围绕基于5G的配电网差动保护通信架构,分析了5G配电网差动保护与无线通信接口设备的通信协议,以及差动业务和三遥业务的共端口可行性,提出了差动保护的流量控制措施。为验证接口方案的可行性,分阶段开展外场联合测试。试运行的结果表明,所提出的硬件接口要求可以实现两类装置的有效对接,确保差动业务可靠投入运行。
5G technology has such advantages as ultra-high reliability and low-latency.It provides good communication foundation for control and protection technology of distribution networks.The distribution network differential protection can not only improve the fault isolation level in distribution network,but also promote the application based on 5G in vertical industry.This paper focuses on the 5G-based distribution network differential protection communication architecture,analyzes the communication protocol of 5G distribution network differential protection and wireless communication interface equipment,as well as the feasibility of the common port of differential service and three remote services,and proposes the differential protection Flow control measures.In order to verify the feasibility of the interface scheme,joint field tests were carried out in stages.The results of the trial operation show that the proposed hardware interface requirements can realize the effective docking of the two types of devices and ensure the reliable operation of the differential service.
