N2 - With the improvement of people's living standards, the problem of voltage qualification rate in remote rural areas has become increasingly prominent. Under heavy load, the line voltage drop is relatively large, which is likely to cause the user voltage at the end of the line to be low. To this end, from an economic point of view, this paper proposes to use the original line to construct a DC transmission path, design a converter group and a switch network, and form an AC-DC distribution modal conversion system for a low-voltage distribution network. By detecting the voltage and current changes on both sides, there is no need for remote communication lines to determine the logic timing of the switches on both sides. The simulation results verify the feasibility of the scheme.
