摘　　要：为了减少多模式联合馈线控制的时延,提升配电网故障识别的准确性,提出基于5G网络切片技术的多模式联合馈线自动化控制方法。利用5G独立组网进行终端通信,联合智能分布式、电压-时间型、主站集中型等3种馈线模式,与继电保护相结合,建立多模式馈线自动化控制方法。根据故障发生时间匹配不同控制逻辑,依据逻辑值对故障电流进行判定与隔离,利用联络开关合闸恢复正常区域供电。实验结果显示,所提方法能够满足某地区配电网的控制需求,准确地判定故障,并将其隔离,快速地恢复供电,应用uRLLC切片技术可满足通信可靠性,使控制时延最短。In order to reduce the time delay of multi-mode joint feeder control and improve the accuracy of distribution network fault identification,a multi-mode joint feeder automation control method based on 5G network slicing technology is proposed.Using 5G independent network for terminal communication,combined with three feeder modes of intelligent distribution,voltage time type and master station centralized type,combined with relay protection,a multi-mode feeder automation control method is established.It matches different control logic according to the fault occurrence time,judges and isolates the fault current according to the logic value,and uses the tie switch to close to restore the power supply in the normal area.The experimental results show that this method can meet the control requirements of a regional distribution network,accurately determine the fault,isolate it,and quickly restore the power supply.The application of uRLLC slicing technology can meet the communication reliability,and minimize the control delay.
