基于4G无线通信的自适应分布式差动保护系统

摘要

随着无线通信技术和智能配电技术的发展,分布式差动保护为配电系统的故障隔离提供了可靠的判据.结合4G高速通信网络的技术特点,提出了一种自适应的分布式差动保护系统设计方案,能够动态根据配电网中拓扑变化对差动保护配置做出针对性变化,有效地减少了配电网运维成本,并且可以对基础设施落后的老城区进行改造,为智能配电网分布式自动化故障处理提供新的解决方案.%With the development of wireless communication technology and intelligent power distribution technology, adistributed differential protection provides a reliable criterion for fault isolation in distribution system.Based on the technical characteristics of 4G high-speed communication network, this paper proposed a design scheme of the adaptive distributed differential protection system, which can dynamically change the differential protection configuration according to the topology change in the distribution network.This design scheme can effectively reduce the distribution operation and maintenance costs, and transform the obsolete infrastructure of the old city.This paper provids a new solution for intelligent distribution network for distributed automation troubleshooting.
