ALEXANDRIA, Va., July 14 -- United States Patent no. 12,683,393, issued on July 14, was assigned to Xcel Energy Inc. (Minneapolis).

"Tripping energy loads during under-frequency events based on rate of change of frequency" was invented by Kevin W. Jones (Minneapolis).

According to the abstract* released by the U.S. Patent & Trademark Office: "Disclosed are systems and methods for tripping energy loads in an energy transmission system based on rate of change of frequency (RoCoF). A method can include: receiving, by a control circuitry of a relay, energy-in-generation information for an energy load, determining a RoCOF for the energy load, identifying presence of first RoCoF conditions, setting first through nth timers based on a determinat...
