Voltage regulation at a remote location using measurements from a remote metering device

A voltage regulator control apparatus for controlling tap position change operation of a voltage regulator, the voltage regulator configured to operatively couple to a local position of an electric power delivery system to regulate a remote voltage at a remote position of the electric power delivery system, the apparatus comprising:

• a remote input for receiving remote electric power information from the remote position of the electric power delivery system;
• and
• a microcontroller operatively coupled to the remote input and including a voltage regulation module for
• receiving the remote electric power information,
• calculating an updated line impedance using a ratio of the remote electric power information including a remote measured voltage to a remote estimated voltage,
• updating the set line impedance with the updated line impedance, and,
• comparing the remote electric power information against predetermined thresholds to determine if the remote position of the electric power delivery system exhibits an out-of-band condition, and
• creating a tap position change command when remote position of the electric power delivery system exhibits the out-of-band condition.

A method for regulating a voltage at a remote location of an electric power delivery system using electric power system information from the remote location and a voltage regulator at a local location of the electric power delivery system, comprising:

• receiving remote electric power system information from the remote location by an intelligent electronic device at the local location in operational communication with a voltage regulator;
• calculating an updated line impedance using a ratio of the remote electric power system information including a remote measured voltage to a remote estimated voltage;
• updating the set line impedance with the updated line impedance;
• and,
• the intelligent electronic device comparing the remote electric power system information against a first threshold to detect a first out-of-band condition at the remote location;
• and,
• the intelligent electronic device upon detecting the first out-of-band condition, sending a command to the voltage regulator to change a tap position to regulate the remote voltage.
