  • Voltage regulation system and method
    Patent number: 9081407
    Abstract: A method for regulating a power line voltage includes determining a slow voltage variation by filtering an actual voltage at terminals of the voltage regulation apparatus. A fast active power variation is determined by filtering a measured active power of the DG system; wherein a first frequency of the slow voltage variation is smaller than a second frequency of the fast active power variation. The voltage regulation apparatus settings are controlled based on the slow voltage variation and a reactive power output of the DG system is controlled based on fast active power variation.
    Type: Grant
    Filed: December 21, 2012
    Date of Patent: July 14, 2015
    Assignee: General Electric Company
    Inventors: Johal Harjeet, Naresh Acharya, Kathleen Ann O'Brien, Xinhui Wu
