Research on Single-Phase Reclosing Strategy of Distributed Power Transmission Lines
The share of distributed power supply in the power grid is gradually increasing, and the reclosing technology after failure can ensure the utilization rate of distributed power supply. Compared with three-phase reclosing technology, single-phase reclosing has higher reliability and safety. The voltage and current components of the composite network in the non-full phase operation of the distributed power supply and shock of voltage and current during reclosing were analyzed. The simulation results show that the voltage and current components agree with the analysis results in high accuracy.
