Abstract
This paper proposes a new control method of the current balancer for single-phase three-wire secondary distribution systems using the correlation and cross-correlation coefficients. The components of the load currents correlative and cross-correlative to the primary side voltage waveform, which correspond to the active and reactive currents, are detected in each feeder, then the reactive and unbalanced-active components are compensated on the source side. The balanced currents with the variable 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. A proto-type experimental system is constructed and tested. Experimental results demonstrate that the balanced source currents with the power factor of 0.9 are obtained in spite of unbalanced load currents.
