Abstract: The line losses of distribution network directly affect power supply enterprise's economic efficiency. Firstly, the relation between line losses and running voltage is analyzed in the paper and a conclusion is drawn that line losses of distribution network are reduced through regulating running voltage. When Electricity quality is guaranteed, increasing properly running voltage can decrease line losses under the condition of the distribution transformer heavy-load operation and increasing properly running voltage can decrease line losses under the condition of the distribution transformer heavy-load operation. But the result is opposite when the distribution transformer is under the condition of light-load operation. Then, the function for running voltage and the least line loss is derived. Finally, dynamic power system experimentations are done. Experimentation results show that the proposed method is efficiency and applicable.
