Based on the existing three- phase unbalanced load control scheme，this thesis is aimed at giving an application analysis so that the three-phase load unbalanced governance could be further advanced. From the economic point of view, by giving a comprehensive economic analysis of the three-phase unbalanced load control scheme based on the commutation method, this thesis attempts to find the optimal solu- tion. A mathematical model is established for the optimal input output ratio of the control scheme by acquiring and analyzing users power consumption data, and developing characteristic group range, and analyzing adjustment action in terms of power consumption in the area. The economi- cally optimal solution to the application of three-phase unbalanced load governance equipment is also to be determined through an analysis of the characteristics of power consumption of the gr
