Abstract: A control system for a voltage regulation device is configured to determine a tap position of a tap changing mechanism of the voltage regulation device, the control system being configured to: determine an internal impedance of the voltage regulation device based on an initial tap position; determine a voltage of the internal impedance based on a measured load current; determine a voltage of the first winding based on the input voltage, the output voltage, and the voltage of the internal impedance; and determine the tap position based on the voltage of the first winding, N, and a voltage of a second winding, where N is an integer value that represents a count of turns on the second winding.

Abstract: A power system can include a first tap changer for a first regulated transformer, where the first tap changer has a plurality of first positions. The power system can also include a second tap changer for a second regulated transformer, where the second tap changer has a plurality of second positions. The power system can further include at least one first instrument transformer coupled to the first regulated transformer. The power system can also include at least one second instrument transformer coupled to the second regulated transformer. The power system can further include a controller coupled to the at least one first instrument transformer and the at least one second instrument transformer, where the controller adjusts the first tap changer to a first adjusted position among the first positions based on the first measurements of the first regulated transformer and the second measurements of the second regulated transformer.
