In this application, the above-mentioned target circuit is a three-phase four-wire system circuit. Through the above-mentioned low-voltage distribution network, medium-voltage or high-voltage power can be converted into a lower voltage to safely supply power to residential, commercial and industrial users. Since the three-phase imbalance in the low-voltage distribution network will affect the safe and stable operation of the power grid and the quality of electric energy, and further affect the user experience, it is necessary to control the phase of the current in the target circuit.

[0032] The above-mentioned plurality of nodes refer to the nodes in the above-mentioned target circuit, and the above-mentioned target node refers to a specific position point in the above-mentioned low-voltage distribution network. The above-mentioned plurality of nodes can be user access points, branch points of lines or any other key positions, and the phase of the current in the plurality of nodes can be controlled by installing phase switches.

[0033] The above-mentioned phase refers to the phase relationship of alternating current in the target circuit. In this application, the above-mentioned phase describes the relative time delay or time advance relationship between three alternating voltage or alternating current waveforms, as well as the relationship between amplitude and frequency. When the amplitudes of three-phase current or three-phase voltage are equal and the phase difference is 120 degrees, the system is in a three-phase balanced state, while when the amplitudes of three-phase current or three-phase voltage are not equal or the phase difference deviates from 120 degrees, the system is in a three-phase unbalanced state.
