【 摘 要 】

In this paper, the objectivity and unpredictability of the three-phase load unbalance (TPLU) for the rural distribution network are proposed. Firstly, the influences of TPLU on the power quality and power loss are analyzed. And then, based on the common managements and governance measures of TPLU, whose typical problems are also introduced. Furthermore, based on the fast phase selection, the concept of the three-phase load balance is defined to describe the basic structure and complementation principles in detail. Lastly, the operating points and control strategies of the commutation equipments are proposed. The verification results show that proposed method is accurate and effective.
