  • PT PRIMARY VOLTAGE RECONSTRUCTION METHOD BASED ON INVERSE BLACK BOX MODEL AND INVERSE ELECTROMAGNETIC DUALITY MODEL
    Publication number: 20250060395
    Abstract: A method for reconstructing a primary voltage of a potential transformer (PT) based on an inverse black box model and an inverse electromagnetic duality model includes: collecting a secondary voltage signal of a power system by the PT, and dividing the secondary voltage signal into a low-frequency voltage component and a high-frequency voltage component; performing primary voltage reconstruction by applying the inverse black box model on the high-frequency voltage component, to obtain a primary-voltage high-frequency voltage component; performing primary voltage reconstruction by applying the inverse electromagnetic duality model on the low-frequency voltage component, to obtain a primary-voltage low-frequency voltage component; and integrating the primary-voltage high-frequency voltage component and the primary-voltage low-frequency voltage component, to obtain the primary voltage of the power system.

  • Tight oil reservoir COflooding multi-scale channeling control system and preparation method
    Patent number: 11702585
    Abstract: A tight oil reservoir CO2 flooding multi-scale channeling control system and a preparation method, including nanoscale CO2 responsive worm-like micellar systems and micron-scale CO2 responsive dispersion gel, are provided. The nanoscale CO2 responsive worm-like micelle system is prepared by CO2 reactive monomers and organic anti-ion monomers stirred in water. The micron-scale CO2 responsive dispersion gel is made of acrylamide, a responsive monomer, a silane coupling agent modified hydroxylated multi-walled carbon nanotubes as raw materials, cross-linked in water.
