What is Three-Phase Unbalanced Treatment Scheme Based on High-Speed Power Line Carrier about?

## Abstract Most of the low-voltage distribution networks are three-phase four wire systems. Because of the quantity and dispersion of single-phase power users, the three-phase load unbalanced problem exists in a large number of low-voltage stations. With the continuous increase of power consumption level of the majority of power customers, the three-phase load unbalanced has become increasingly prominent in low-voltage station area. In this paper, the mechanism of three-phase unbalance generation and the defects of traditional treatment methods are introduced. On this basis, a three-phase unbalanced treatment scheme for low-pressure station area is proposed. The scheme can test out three-phase imbalance of low-voltage substation area quickly and accurately, and adjust the load phase sequence in real time without power failure through the intelligent commutation switch system, so that three-phase load in the station area lies a comparatively balanced condition. The scheme can cut down the loss of transformer and line caused through unbalanced three-phase load e in nicely. And it can restrain single-phase overcurrent, and solve the problem of terminal low voltage treatment.
