The invention discloses a site selection method for a three-phase imbalance automatic commutation device. The site selection method comprises the following steps: S1, obtaining branch line three-phase current of the three-phase imbalance automatic commutation device; s2, constructing a first objective function of the three-phase imbalance automatic commutation device; s3, constructing a second objective function of the three-phase imbalance automatic commutation device; s4, constructing constraint conditions of the three-phase imbalance automatic commutation device; and S5, finishing site selection of the three-phase imbalance automatic commutation device. According to the method, the sum of the construction cost and the operation and maintenance cost of the minimum commutation device system is taken as an objective function, safety factors are considered, and the reduction of the three-phase unbalance degree of the low-voltage side of the district distributor as far as possible is taken as a secondary object
