摘　　要：传统就地型馈线自动化(feeder automation,FA)采用电压时间配合策略,故障自愈(包括故障区段隔离和非故障区段供电恢复)过程开关动作次数多、用户停电时间长。针对此问题,提出一种快速故障自愈的就地型馈线自动化策略,可显著减少用户停电时间。该策略中,分段开关取消失压分闸功能,新增失压后合位来电检故障加速分闸、失压后合位短时来电分闸、合闸到故障加速分闸并闭锁等功能,与出线开关重合闸配合完成故障自愈。与常规电压时间FA策略相比,该策略可减少1次出线开关重合闸,有效减少线路开关动作次数和故障停电时间。通过实验室真型系统测试和现场实际应用,验证了所提出的快速自愈策略正确可行。Traditional local feeder automation(FA)adopts voltage-time strategy,which results in multiple switch actions and long user power outage times during fault self-healing,including fault section isolation and power restoration of non-fault sections.A fast self-healing local feeder automation strategy that can significantly reduce power outage time was proposed for solving this problem.In this strategy,the segmented switch eliminates the function of opening when voltage loss,and adds functions such as fault detection,acceleration opening after voltage loss,short-term power opening following voltage loss,and accelerated opening with locking when closing onto a fault.This works in cooperation with the reclosing of outline switch to complete fault self-healing.Compared with the traditional voltage-time FA strategy,this strategy can reduce one reclosing of the outline switch,effectively reducing the number of line switch actions and fault outage time.The correctness and feasibility of the proposed fast self-healing strategy have been verified through true-to-type platform system testing and practical application.
