Development of a Mobile Diagnosis Complex for Power Transformers in Operating Modes Based on Online and Predictive Analysis Models

Abstract

The article is dedicated to development of a prototype of the HW/SW diagnostic complex for power transformers based on the analysis of their subsystem condition, in which the physical pro- cesses are most interdependent. Adaptation and fi ne tuning of online and predictive analysis models of electromagnetic and insulation sub- systems are performed in interaction with the database and the moni- toring systems for the following hybrid parameter integration, which enables a more precise interpretation of measurement results and selection of algorithms for further reliable operation. The article pro- vides new results: the calculated model of electromagnetic parameters of a three-phase power transformer in operating modes; the algorithms of hybrid integration of subsystem modules based on a detected correlation between their parameters; study of the comparative simulation by test and author's algorithm of dissolved gas analysis result interpretation.
