| Summary: | 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. |
