The present invention discloses an outgoing line load three-phase integration protection, regulation and control method which obtains the power consumption data of a user power consumption terminal, determines whether the user power consumption terminal generates the three-phase unbalance according to a three-phase unbalance degree, if the user power consumption terminal is determined to generate the three-phase unbalance, carries out the three-phase balance degree optimization on the user power consumption terminal according to a preset balance parameter and the three-phase unbalance degree. By the above technical scheme, the balance of cooperating the three-phase load can be realized, the anomalous change of power supply voltage and current is prevented from burning out the power consumption equipment, at the same time, the line loss is reduced effectively. Meanwhile, a multi-stage line loss statistics analysis method of public transformer power supply range-outgoing line branch-branch ...
