METHOD AND APPARATUS FOR PRODUCING DATABASE OF REACTOR SATURATION POINTS

The present invention relates to a method and a device for producing a saturation point database of a reactor and, more specifically, to set a saturation determination value to determine a saturation point of a reactor; compare the saturation determination value with harmonic components in a current flowing through the reactor; determine whether the reactor is disposed in a saturation region or a normal operation region; store a current and frequency data in a database at this time when the reactor is disposed in the saturation region; and enable a user to obtain information about the correct operation region of the reactor.
