5G独立组网模式下的配网保护配置策略及应用

广覆盖高可靠低延时通信的5G网络,对打通配网终端设备之间的互联互通"最后一公里"问题有着极高的应用价值.为提升5G独立组网模式下配网保护的实用化水平,首先分析了配网保护的通信资源需求,并根据5G配网保护的总体架构,通过时钟信号和数据信号同源传输的方式提出了可靠性更高的对时方案.同时,在城区配网开展了差动保护和区域保护的...

Configuration strategy and application of distribution network protection based on standalone 5G

The 5G network,with its characteristics of wide coverage,high reliability and low delay communication,has a high application value in solving the‘last kilometer’problem in interconnection between the terminal equipment of a distribution network.To improve the practical level of distribution network protection based on standalone 5G,the communication resource requirements of distribution network protection are analyzed first.Then,given the overall structure of 5G distribution network protection,a more reliable time synchronization scheme is proposed through the same source transmission of clock signal and data signal.At the same time,differential protection and regional protection are applied in an urban distribution network.The differences between the two protection methods in overhead lines and cables are analyzed.The results show that overhead lines are recommended for regional protection,and cables can be compatible with differential protection and regional protection.
