Power distribution system based on two-wire system on-load capacity-regulating transformer

The invention discloses a power distribution system based on a two-wire system on-load capacity-regulating transformer, which relates to the technical field of power distribution and comprises a single-phase reverse-phase transformer (1), a three-phase on-load capacity-regulating transformer (2) and a control system (3). According to the power distribution system based on the two-wire system on-load capacity-regulating transformer, on the basis of reducing the use of power electronic devices, only two-phase power is used for providing three-phase power meeting the requirements for the power distribution area, and the related cost is reduced while the power utilization requirement of the area is met. By using the capacity regulating transformer, high capacity is used under the condition of heavy load, and low capacity is used under the condition of light load, so that the internal loss of the transformer is reduced, and the operation stability and economical efficiency of the system can be effectively improved
