System and method for controlling voltage on a distribution feeder

摘要

A system (100) for controlling voltage on a distribution feeder (106) includes a plurality of capacitor banks (102a-102n) that can be connected to or disconnected from the distribution feeder. A first bank is configured to connect to the distribution feeder when a first voltage is below a first lower threshold value and to connect to the distribution feeder when the first voltage is above a first upper threshold value. The first upper threshold and first lower threshold are determined based off an operational set point. The system further includes a sensor (109) configured to measure the first voltage and a controller (108) in operable communication with the plurality of capacitor banks configured to determine the operational state of the first and second capacitor banks and, based on the first voltage, send a first instruction to the first capacitor bank, the first instruction causing the capacitor bank to vary the operational set point.
