摘要：
馈线自动化技术(Feeder Automation,FA)作为配电网络安全运行的重要保障,在提高供电可靠性方面有着至关重要的作用.针对双电源配电网络三相短路故障,在集中式和分布式馈线自动化控制的基础上提出了一种集分联合馈线自动化控制方法,即通过配电终端上下游间的交互通信快速定位并隔离故障,再经主站控制联络开关,下发控制命令,恢复非故障区供电.与集中式馈线自动化控制方法相比,所提集分联合馈线自动化控制方法在保留主站检测,遥控功能的前提下具有更快的故障区域隔离和供电恢复速度.
Feeder automation technique guarantees the safety operation of the distribution network,which is important for improving the reliability of power supply.To solve the problem of three-phase short-circuit fault in the dual-power distribution network,a combined centralized and distributed feeder automatic control method is proposed based on the centralized and distributed feeder automation control.The fault is located and isolated via the communication between the upstream and downstream of the feeder terminal unit.Then the switch is controlled by the master station and the power supply in the non-fault area is restored.Compared with the centralized feeder automation control method,the proposed control method is advantageous in maintaining the detection and remote control functions of the master station,and it is faster in isolating the fault and restoring the power.
