US Patent Issued to HITACHI ENERGY on Aug. 4 for "Method for fast calculation of electrical network impedances at many frequencies and many system conditions" (North Carolina Inventor)

ALEXANDRIA, Va., Aug. 5 -- United States Patent no. 12,699,121, issued on Aug. 4, was assigned to HITACHI ENERGY LTD (Zurich, Switzerland).

"Method for fast calculation of electrical network impedances at many frequencies and many system conditions" was invented by John Paul Daniel (Apex, N.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The calculation of impedances at different frequencies and under a variety of system conditions is computationally burdensome. Accordingly, disclosed embodiments generate a set of reduced bus matrices, retaining nodes of interest from a square bus matrix that models an electrical network, for a plurality of frequencies. This set of reduced bus matrices retains the computat...
