Latest Patents

One of his latest patents is a "Magnetic field based wireless GMD/EMP-E3 impact monitoring device." This system monitors the impact of geomagnetic disturbances (GMDs) or the E3 component of electromagnetic pulses (EMP-E3). It involves a transducer that generates a signal in response to the magnetic field of a current-carrying element in a transmission line. The transduced signal reflects harmonic characteristics, which are amplified, filtered, and digitally converted. Excessive impact is detected when a threshold condition is met regarding total harmonic distortion (THD). The THD can be calculated using various methods, including Fourier transforming the digital signal or employing a phase-sensitive detection algorithm.

Another significant patent is for "Power system inertia estimation using synchrophasor frequency measurements." This method involves receiving power system frequency measurements from multiple phasor measurement units (PMUs) over time. It generates multi-dimensional ellipsoids based on these measurements and performs regression analysis to establish a predictive relationship between graphic parameter values and inertia values of the power system. This innovative approach allows for accurate estimation of current inertia values based on the extracted parameters.
