Dielectric state analysis method and system, computer and storage medium

Abstract

The invention provides a dielectric state analysis method and system, a computer and a storage medium. The method comprises the following steps: iteratively calculating a simulated imaginary part integral according to a real part interpolation step length until whether the simulated imaginary part integral is smaller 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 the imaginarypart interpolation step length, until the simulation real part integral is smaller than the preset resolution; comparing the simulated real part integral with the actual real part integral; obtainingthe capacitance information and the polarization process imaginary part information, and finally obtaining the dielectric state according to the conductance information, the polarization process realpart information, the capacitance information and the polarization process imaginary part information, so that the dielectric state can be accurately analyzed and judged, misjudgment, missed judgmentand misjudgment are avoided, and the operation and maintenance cost of power equipment is saved.

Problems solved by technology

[0003] In the existing research and engineering practical application, it is still impossible to realize the decoupling analysis of the dielectric response measurement results of the dielectric and electric equipment, so it is impossible to obtain the conductance process, polarization process and infinite frequency capacitance process of the dielectric and electric equipment. This leads to the inability to accurately judge the state of the dielectric / power equipment, which brings a lot of inconvenience to the state diagnosis of the power equipment in the power system, and easily causes misjudgment, missed judgment, and misjudgment
