摘要(Abstract)：

“双碳”背景下，随着DG（分布式电源）接入农村配电网比例的不断增加，传统电压时间型FA（馈线自动化）会出现分段开关失压分闸失败问题，导致开关动作逻辑错误，无法正确隔离故障区段。针对DG的电压支撑能力和故障电流幅值受限特点，分析了DG接入对农村配电网电压时间型FA双侧失压分闸功能的影响，研究了基于DG装机容量的失压分闸判据整定方法。最后，在仿真模型中验证了所提方法的正确性。
In the context of carbon peaking and carbon neutrality goals, the increasing proportion of large-scale integration of distributed generation(DG) integrated into rural distribution networks may lead to switching fault due to voltage loss of the section switch of the traditional voltage-time type feeder automation, resulting in operation logic fault of the switch and failure in isolating the faulty section. In view of the voltage support capability and the fault current amplitude limitation characteristics of DG, the impact of the DG integrated into the rural distribution networks on dual-side switching function due to voltage loss of the voltage-time type feeder automation is analyzed, and the criterion setting method for switching fault due to voltage loss is studied. Finally, the proposed method is proved correct in a simulation model.
