Optimizing Power Factor Correction Between Voltage Regulators

摘要

Systems and methods for optimizing power factor correction between voltage regulators are described herein. The system can include a leader voltage regulator controller coupled to a first voltage regulator and a follower voltage regulator controller coupled to both a second voltage regulator and the leader voltage regulator controller. The leader voltage regulator controller can determine a difference in measured power factors between the first voltage regulator and the second voltage regulator. The leader voltage regulator controller can also initiate an adjustment of a tap position of the first voltage regulator or the second voltage regulator. Alternatively, instead of leader and follower voltage regulator controllers, the system can utilize a single connected voltage regulator controller that determines differences in measured power factors between a first voltage regulator and a second voltage regulator and initiates an adjustment in a tap position(s) when appropriate.

1. A method of optimized power factor correction, comprising,
comparing, by a controller, a difference in measured power factors between two voltage regulators with a predetermined maximum difference; when the difference is determined to be greater than the predetermined maximum difference, storing, by the controller, the difference as a previous difference in measured power factors; adjusting, by the controller, a tap position of one of the voltage regulators; comparing, by the controller, a second difference in measured power factors between the two voltage regulators with the previous difference in measured power factors; and when the second difference in measured power factors is not less than the previous difference in measured power factors, returning, by the controller, the tap position of the one of the voltage regulators to a prior tap position.
