摘要
为提升配电网自动化系统的通信可靠性与实时性,针对传统单一通信制式存在的覆盖和时延问题,设计了窄带物联网(Narrow Band Internet of Things,NB-IoT)与4G双模冗余架构,包括硬件部署和3种冗余模式(热备份、冷备份、负载分担)。通过案例分析和实际实施,优化了关键节点的通信性能,显著降低了中断率,缩短了故障隔离时间,并控制了传输时延。研究结果表明,该方案能够有效保障配电网的稳定运行,并为未来通信优化奠定基础。
In order to improve the communication reliability and real-time performance of distribution automation system,aiming at the problems of coverage and time delay existing in traditional single communication system,a dualmode redundant architecture of Narrow Band Internet of Things(NB-IoT)and 4G is designed,including hardware deployment and three redundancy modes(hot backup,cold backup and load sharing).Through case analysis and practical implementation,the communication performance of key nodes is optimized,the outage rate is significantly reduced,the fault isolation time is shortened,and the transmission delay is controlled.The research results show that the scheme can effectively guarantee the stable operation of distribution network and lay the foundation for future communication optimization.
