A novel method for balancing of three-phase network with a single phase load

Abstract

When a three-phase power line connected to unbalanced loads, its terminal voltages and line currents become also unbalanced. The most unfavorable load for three phase network or stand-alone generator is a single-phase load. Present study suggests a novel method for operating single-phase load connected to three-phase network while keeping generator voltages and currents fully symmetrical. Theoretical, simulation, and experimental results are presented in order to validate the analysis and principle of operation.
