摘　　要：分布式馈线自动化(FA)系统关于故障定位与隔离方面的研究日趋成熟,而在供电恢复方面略显不足。为了进一步提升分布式FA系统的供电恢复能力,解决因故障点位置不同而导致供电恢复困难的问题,提出了一种可用于多联络、多分支配电网的供电恢复方案,通过建立负荷评估模型和待恢复区拓扑模型,由代理终端负责通过单联络开关、单联络开关切负荷完成供电恢复的工作,实现了非故障区域的供电恢复,并通过实时数字仿真仪(RTDS)验证了控制策略及其算法的有效性。Feeder automation(FA)system is becoming more and more matured on fault location and isolation,but it is slightly insufficient in power supply recovery.In order to further improve the power recovery capability of distributed FA system,solve the tricky problem of power supply recovery due to different location of the fault,a power supply restoration scheme that can be used for distribution network with multi connection and multi branch is proposed.The agent terminal completes the power recovery work by closing single interconnection switch,single inter-connection switch with load cutting on the basis of load evaluation system and topology model for the waiting recovery region,which realizes the restoration of power supply in the non-fault area.The effectiveness of control strategy and algorithm are verified by real-time digital simulator(RTDS).
