Electronic transformer high-frequency data analysis and storage method and system

Abstract

The application provides an electronic transformer high-frequency data analysis and storage method and system. The method comprises the following steps: calculating coarse amplitude information, coarse phase information, fine amplitude information and fine phase information of measurement data according to message data output by an electronic transformer; realizing electronic transformer measurement data type identification by performing feature analysis on the coarse amplitude information and the coarse phase information in a short time domain, and judging whether the electronic transformer measurement data is steady-state data or transient-state data; realizing differentiated data storage according to the electronic transformer measurement data type identification, taking a long-time coarse storage method for the steady-state data, and taking a short-time fine storage method for the transient-state data. The application solves the technical problem that the analysis and storage method of the electronic transformer measurement data cannot adapt to various operating states of the electronic transformer, resulting in insufficient storage dimensions of the electronic transformer measurement data and the inability to support online evaluation of the operating state of the electronic transformer.
