Abstract
A method of controlling a regulating transformer with a settable translation ratio, switchable between a first and second AC-mains includes the following operations: detecting phasor data of phasors of the first and/or second AC-mains; determining an equivalent circuit diagram with equivalent circuit diagram parameters for the first AC-mains; determining a load model with load model parameters for the second AC-mains; determining the equivalent circuit diagram parameters and the load model parameters from the phasor data; and when switching over to a desired translation ratio is to take place: predicting a working point of the second AC-mains for the desired translation ratio; checking a stability criterion in the second AC-mains for the predicted working point; and switching over to the desired translation ratio is carried out upon the stability criterion being fulfilled, but otherwise not switching over to the desired translation ratio.
