Abstract
A utility power regulation system includes a power converter configured to regulate one or more of a voltage and a power factor at the primary side of a step-up transformer, or at a load electrically connected to a load feeder line, based on an estimated primary-side line voltage signal. The system includes a voltage estimation circuit configured to estimate the primary-side line voltage signal from one or more signals received from a secondary-side voltage sensor, regulator line current signal, and a primary-side load feeder-line current sensor.
