Low-voltage load balance regulation and control system

The invention provides a low-voltage load balance regulation and control system. The low-voltage load balance regulation and control system detects the load capacity of each phase of power supply line through a phase electricity detection module; the phase power controller judges the balance degree of the three-phase power supply lines according to the load capacity of each phase of power supply line, and when the three-phase power is unbalanced, the power supply line with the maximum operation load capacity and the power supply line with the minimum operation load capacity are called; a three-phase balance adjustment process is started, the electricity users in the power supply line with the maximum operation load capacity are allocated to the power supply line with the minimum operation load capacity for power supply, and three phases tend to be balanced, so that the unbalanced state of the three phases is improved, the line loss and the unbalance degree of a power network are reduced, and good operation of
