Abstract

In this paper

a kind of three-phase load balancing technology based on automatic commutation is introduced. The load is distributed to each phase sequence by way of on line adjusting the phase which is connected by the residential load. Multiple objective optimization function is established and is subject to optimization solution through load control strategy which is based on the fuzzy C mean clu-stering algorithm to obtain the optimal phase configuration scheme of the load terminal. The feasibility of the algorithm is verified by a simulation example. Finally

the three-phase load balancing device is installed in the low voltage distribution station. It is shown by the interconnection experimental result that the three-phase load balance device can decrease effectively network of unbalanced and improve the quality of the power supply of the user

reduce the line loss. The validity and efficiency of the three phase load balancing device is verified.
