Flexible multi-states switch(FMSS) based on power electronics technology can realize the flexible interconnection between feeders, elastically control feeder power flow and solve the serious unbalance of feeder power flow in the distribution network. Based on the traditional flexible multi-state switch, this paper proposed that using flux-controlled variable reactor as the topology of flexible multi-states switch in distribution network. Firstly, flux-controlled variable reactor's principle was introduced; Then, we analyzed the principle of feeder power flow's control using variable reactor; After that, the control strategy for the flexible multi-states switch with different access methods was proposed; At last, a Matlab simulation model and the prototype experiment platform were built. The results verified the power flow control function of flexible multi-states switch and effectiveness of proposed controlled strategy.
