Abstract (en)
[origin: US2019064858A1] A method for controlling a value of a voltage at a conductor to which at least one secondary winding of a first steppable transformer and a secondary winding of a second steppable transformer are connected is provided. The method includes: if a voltage deviation of the voltage at the conductor from a voltage setpoint value is within a first range around the voltage setpoint value, and if an overall deviation of a sum of the voltage deviation and a reactive current deviation from the voltage setpoint value respectively for the first and the second transformer is outside of a second range, which is larger than the first, around the voltage setpoint value: setting a delay time for stepping the first transformer and/or the second transformer in such a way that stepping of the first or the second transformer that counteracts the voltage deviation is prioritized.
