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.
