US Patent Issued to Raytheon on May 20 for "Dynamic stabilizer for hybrid energy storage machinery with power system experiencing torsional oscillations" (Massachusetts Inventor)

ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,781, issued on May 20, was assigned to Raytheon Co. (Arlington, Va.).

"Dynamic stabilizer for hybrid energy storage machinery with power system experiencing torsional oscillations" was invented by Stephen B. Kuznetsov (Marlborough, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method of stabilizing a power supply includes, receiving, at a controller connected to an alternating current (AC) excitation source, a plurality of system inputs. The method further includes obtaining a harmonic spectrum of the load current on a hybrid asynchronous induction machine, determining based on the harmonic spectrum, a first low frequency spectrum of the lo...
