配电自动化在10 kV线路故障隔离、转供电应用逐渐加强,配电主站将主站与电压-时间协同型自愈策略广泛应用于10 kV线路故障的定位、隔离,实现自愈转供电,提高了供电可靠性;当配电主站采集配电自动化开关闭锁信号缺失、故障边界不确定时,自愈策略自动终止,则造成变电站出线开关和配电线路上的自动化开关重复动作或故障区段进一步扩大.后备策略利用现有的调度自动化、配网自动化等系统数据信息,在主站自愈策略实施终止后启用后备策略进行综合分析快速缩小配电线路故障范围、隔离故障区段.
Analysis of Backup Strategy and Method of Self-Healing Mode of Power Distribution Master Station+Voltage Time
The application of distribution automation in fault isolation and power supply transfer of 10kV lines is gradually strengthened.The distribution master station widely applies the self-healing strategy of master station and voltage-time coordination to fault location and isolation of 10kV lines to realize self-healing power supply transfer and improve the reliability of power supply.When the main distribution station collects the loss of distribution automation switch lock signal and the fault boundary is uncertain,the self-healing strategy automatically terminates,resulting in repeated action of the substation outlet switch and the automatic switch on the distribution line or further expansion of the fault section.By using the existing system data information such as scheduling automation and distribution network automation,the backup strategy can be used for comprehensive analysis after the self-healing strategy of the main station is terminated to rapidly narrow the fault range of the distribution line and isolate the fault section.
