METHOD AND SYSTEM FOR ONLINE FERRORESONANCE DETECTION

摘要

The invention concerns a method and a system for online ferroresonance detection in a high voltage electrical distribution network. The method includes: -Overflux detection (23),which acts as the start element, overflux being set if the flux is greater than a threshold for specified time duration, -mode verification (26) which is to recognize the modes of the ferroresonance, a fuzzy logic method being used to discriminate the ferroresonance modes.
