Three-phase imbalance automatic adjustment method based on load prediction

The invention provides a three-phase imbalance automatic adjustment method based on load prediction. The method comprises the following steps: installing a plurality of phase modulation switches in each branch of a transformer area; determining a user power supply phase sequence according to the user access file, and establishing a low-voltage transformer area initial topological relation; acquiring historical power supply data of the users, and predicting the load of each user by using the low-voltage user load prediction model; calculating the three-phase unbalance degree of each interval section, and determining the interval section needing phase modulation; performing phase modulation by using a phase modulation switch, recording the actual power supply phase sequence of each user after each phase modulation, and updating the topological relation of the low-voltage transformer area; and coordinating the action sequence of the phase modulation switch of each node until the three-phase unbalance degree of e
