Title:
POWER SUPPLY TIE TRANSFORMER, AND REGULATION AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/051839
Kind Code:
A1
Abstract:
The present application discloses a power supply tie transformer, and a regulation and control method therefor. The power supply tie transformer comprises: a multi-phase parallel transformer, a multi-phase series transformer, and a plurality of safety protection auxiliary adjusting devices. Head terminals of the primary side of the multi-phase parallel transformer are all connected to a first line; the secondary side of the parallel transformer is provided with at least one power supply winding and a plurality of asymmetric windings; the power supply winding is connected to a power supply end; the plurality of asymmetric windings are respectively interconnected to the adjacent phase asymmetric windings of the secondary side of the parallel transformer by means of switch bridge arm modules respectively corresponding to the plurality of asymmetric windings to obtain a first electrical quantity; the first electrical quantity is coupled to the primary side of the series transformer by means of the secondary side of the corresponding series transformer; the plurality of safety protection auxiliary adjusting devices are connected in series between the first line and a second line. The present application realizes transmission of electric energy of a first line and a second line to a power supply end, ties the first line and the second line, and realizes mutual electric energy transmission at specified power between the first line and the second line.
