The invention discloses a three-phase imbalance regulation method capable of reducing a network loss. The three-phase imbalance regulation method is characterized in that integrated minimum loss and optimal commutation operation are provided for three-phase imbalance regulation through considering the influence of three-phase imbalance on the network loss, the influence of a single-phase load on the network loss and the influence of a line loss on imbalance degree. The invention further provides an implementation method. Commutation switch modules and a central control area module are arranged; the commutation switch modules are arranged on various load branches in a power distribution network; all commutation switch modules are intensively connected to the central control area module; and three phases of current input ends of the commutation switch modules are connected with three phases of lines and three phases of current output ends of the commutation switch modules are connected with a user. The three-ph
