Patent ID: 8427131

Claim:
A system for regulating a remote voltage of an electric power delivery system, comprising: a voltage regulating device operatively coupled to a local portion of the electric power delivery system and configured to regulate the remote voltage by selecting among a plurality of taps on a transformer; a metering device in communication with a remote portion of the electric power delivery system to obtain remote power system data, including a transmit module for transmitting the remote power system data; and, a voltage regulator control in communication with the voltage regulating device and the metering device, comprising: an input for receiving the remote power system data from the metering device; and, a microcontroller in operational communication with the input for receiving the remote power system data comprising a voltage regulation module for calculating an updated line impedance using a ratio of the remote power system data including a remote measured voltage to a remote estimated voltage; updating the set line impedance with the updated line impedance; and, producing a tap change command for the voltage regulating device upon detecting an excursion of the remote power system data from an in-band area to an out-of-band area.
