Document Type and Number:
WIPO Patent Application WO/2021/088453
Kind Code:
A1
Abstract:
Disclosed are a dielectric state analysis method and system, a computer and a storage medium. The method comprises: iteratively calculating a simulated imaginary part integral according to a real part interpolation step size until the simulated imaginary part integral is less than a preset resolution, and comparing the simulated imaginary part integral with an actual imaginary part integral to obtain conductance information and polarization process real part information; iteratively calculating a simulated real part integral according to an imaginary part interpolation step size until the simulated real part integral is less than the preset resolution, and comparing the simulated real part integral with an actual real part integral to obtain capacitance information and polarization process imaginary part information; and finally obtaining a dielectric state according to the conductance information, the polarization process real part information, the capacitance information and the polarization process imaginary part information. In this way, a dielectric state can be accurately analyzed and determined, incorrect identification, omitted identification and erroneous identification are avoided, and the operation and maintenance costs of a power device are saved.
