ALEXANDRIA, Va., March 3 -- United States Patent no. 12,566,198, issued on March 3, was assigned to S&C Electric Co. (Chicago).

"PMU algorithm" was invented by Michael Quinlan (Bolingbrook, Ill.) and Yoav Sharon (Evanston, Ill.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system and method for generating phasors having a phase angle and magnitude from a sinusoidal power signal, and using the phasors to generate a frequency and RoCoF of the power signal. The system and method provide improvements over known systems and methods by correcting the frequency of sensor signals, providing a simplified phasor correction equation, reducing errors in a non-recursive DFT algorithm, improving frequency estimation by...
