Three-phase load imbalance treatment method and device based on rural power grid

The invention belongs to the field of three-phase imbalance treatment, and provides a three-phase load imbalance treatment method and device based on a rural power grid, and the method comprises the steps: obtaining transformer area load data, calculating the Bayesian mean value of each three-phase load switch, and determining the installation positions of the three-phase load switches according to the sorting result of the Bayesian mean values; based on the determined installation position of the three-phase load switch, determining the installation position of the flexible commutation device; periodically acquiring three-phase current and three-phase voltage of a power grid and voltage, current and commutation times of a three-phase load switch; whether the unbalance degree of the three-phase load is higher than an unbalance degree threshold value or not is judged according to the collected data, if yes, MIV values are output through iterative calculation according to a trained commutation algorithm model,
