This article analyzes the causes and harms of three-phase load imbalance in the three-phase four-wire distribution network system by investigating and researching the three-phase load imbalance in the distribution network system, and the three-phase load imbalance intelligent control system scheme is proposed in conjunction with the actual situation, introducing control strategy and working principle. By selecting a typical station for installation and trial operation, the calculation and analysis results show that after the equipment is put into operation, it can effectively reduce the power loss, improve the utilization efficiency of the distribution transformer station, and ensure the long-term stable and efficient operation of the distribution network system, it also proves that the power quality in the low-voltage distribution network is verified.
