The invention discloses a three-phase load automatic balance single-phase electric energy metering apparatus and a control method thereof. The apparatus has the conventional single-phase electric energy metering function, and also can automatically switch a distribution network load controlled by the output end from one phase with relatively high load into one phase with relatively light phase, soas to solve the problems of load loss, danger in operation and the like caused by the fact that the existing manual operation mode needs load shedding. The apparatus comprises an electric quantity collection module and a metering module, and also comprises a three-phase phase voltage collection and transmitting module, a three-phase output control switch, an automatic control circuit, and a rectifying power supply used for converting a three-phase high-voltage alternating current into a single-phase low-voltage direct current; the three-phase output control switch is mounted on the three phases input by the electric
