The invention relates to an intelligent electric meter box and a control method thereof, and belongs to the technical field of electric meter boxes. The electric meter box comprises a box body, wherein a
data acquisition module, a processor, an
electric energy management module and a
solid-state
relay module are integrated in the box body, the output end of the
data acquisition module is connected with the input end of the
solid-state
relay module, the output end of the
solid-state
relay module is connected with the processor and is used for isolating
voltage and current information acquired from the
data acquisition module; and the processor is connected with the
electric energy management module, the
electric energy management module comprises an electric reactor, a PWM controllable
rectifier and a
capacitor which are connected in sequence, and the PWM controllable
rectifier is formed by connecting a three-phase bridge arm
branch composed of a switching tube and a fly-wheel
diode. According to the intelligent electric meter box,
electricity utilization information of multiple users can be collected through one box, and the size of the electric meter box is reduced; and before the
electricity consumption of the user is calculated, the electric
energy management module is used for carrying out reactive compensation on the
power grid in an undervoltage state, so that the stability and the reliability of
electricity consumption calculation are ensured.
