Abstract

This paper proposes a new control method of the current balancer in single-phase three-wire secondary distribution systems using the correlation function. The components of the load currents correlative to the primary side voltage waveform, which correspond to the active currents, are detected in each feeder, then the non-active and unbalanced-active components are compensated on the source side. The balanced currents with unity power factor are obtained in each feeder. The basic principle of the proposed method is discussed in detail, and then confirmed by digital computer simulation. Digital computer simulation results demonstrate that the balanced source currents with unity power factor are obtained in spite of unbalanced load currents.
