To solve the problem of three-phase load unbalance in the low-voltage distribution area

it introduces a three-phase load unbalanced solution based on phase-oriented balance.Firstly

by transferring the partial load of the heavy-load phase to the light-load phase in accordance with the control strategy of the conversion device and the overall dispatching strategy of the system

the unbalance degree of the low-voltage distribution network can reach the standard.Secondly

to minimize the impact of the commutation process on users

it introduces a non-intrusive load identification technology to eliminate circuits where single-phase non-variable frequency induction motors are in operation.Finally

the device test verifies that the conversion device can achieve commutation without power interruption under the load.The test results show that this system can effectively solve the problem of load imbalance in low-voltage distribution networks

verifying the feasibility and correctness of the load imbalance suppression system in low-voltage distribution networks.
