Three-phase unbalance is one of the power quality problems. For the power quality problem caused by the three-phase unbalance phenomenon on the load side in the low-voltage distribution network, combined with the characteristics of the three-phase four-wire system of the distribution network in China, the three-phase unbalance adjustment is studied. The device control strategy is selected, and the three-phase four-bridge arm topology and the three-phase current real-time detection method based on instantaneous reactive power theory are selected. The experimental model is built by MATLAB/Simulink to verify the feasibility of the method.
