Abstract: The system and method for unbalanced current adjustment from capacity increase and phase-splitting output of distribution transformer according to embodiments of the present invention are provided, in which the system for unbalanced current adjustment from capacity increase and phase-splitting output of distribution transformer includes a single-phase transformer, a single-phase bridge rectifier, and a three-phase full-bridge inverter. The high-voltage side of the single-phase transformer is connected to the high-voltage side of the distribution transformer. The single-phase bridge rectifier connected to the low-voltage side of the single-phase transformer converts the AC power from the single-phase transformer into the DC power for the three-phase full-bridge inverter. The three-phase full-bridge inverter is connected to the three-phase lines through the three-phase reactors.

Abstract: Embodiments of this invention discloses a split-phase output power adjustment system, adjustment method, and storage medium in a low voltage transformer area.

The adjustment power supplies connected to the split-phase power adjustment modules, and total power P of the adjustment power supplies complying with a relationship as follows: P=Pt=PG1+PG2+ . . . . PGn; wherein Pt is power required to comply with three-phase current unbalance adjustment of a distribution transformer, PG1, PG2, . . .

Abstract: In the present invention, a system and a method for unbalance adjustment for inverter split-phase controlling and distribution transformer current are provided, in which the system for unbalance adjustment for inverter split-phase controlling and distribution transformer current includes a distributed power supply and a three-phase full-bridge inverter. The three-phase full-bridge inverter is connected to the distributed power supply, and the three-phase full-bridge inverter is connected to a three-phase line through a three-phase reactor. When an unbalance degree corresponding to the three-phase line is greater than a preset starting value, a three-phase compensation current reference value is obtained according to the present front-end three-phase load current, back-end three-phase load current and capacitor voltage control component, such that the three-phase full-bridge inverter can output the three-phase compensation current based on the three-phase compensation current reference value.
