Abstract

The present disclosure relates to a capacitor bank controller that automatically determines the size of a capacitor bank using wireless current sensors. The capacitor bank controller determines a first capacitor bank size estimate using voltage and current measurements from when the capacitor bank is open and when the capacitor bank is closed a first time. The capacitor bank controller determines a second capacitor bank size estimate by using voltage measurements and current measurements from when the capacitor bank is open and when the capacitor bank is closed a second time. The capacitor bank controller determines a filtered capacitor bank size estimate based on the first capacitor bank estimate and the second capacitor bank estimate and controls operation of the capacitor bank based on the filtered capacitor bank size estimate.
