Asymmetric loop closing power regulation control method for phase-shifting transformer

The invention relates to the technical field of power distribution network closed-loop transfer control, in particular to an asymmetric closed-loop power regulation control method for a phase-shifting transformer, and the method comprises the steps: entering a field parameter detection stage: detecting bus voltage amplitudes and voltage phase parameters at two sides of a closed-loop point with a closed-loop demand through a voltage transformer, the two sides of the closed-loop point being an S side and an L side respectively; determining the type of the loop closing scene and a phase difference judgment factor by using the voltage amplitude and the voltage phase of the buses at the two sides of the loop closing point detected in the field parameter detection stage; phase modulation transformation ratio parameter calculation and gear selection: based on the phase difference judgment factor and the actual gear of the transformation ratio of the phase-shifting transformer loop closing device, performing gear con
