【 摘 要 】

As the low-voltage distribution network contains many three-phase unbalanced loads and single-phase loads, and the sequence of power consumption of different types of loads varies greatly, the actual power loss of the network increases more than that under three-phase balance. This paper proposes a loss reduction strategy based on phase swapping. By swapping phase of loads, it makes the three-phase transmission power of each branch realize balance in a long period, thus achieving the objective of loss reduction.
