Abstract

This invention proposes a three-phase comparative analysis system and method for a main transformer. The system includes a multi-source data acquisition and preprocessing module, a three-phase characteristic multi-dimensional comparison module, an anomaly level intelligent judgment module, and a personalized operation and maintenance strategy recommendation module. The system's implementation involves: first, the multi-source data acquisition and preprocessing module collects and fuses the three-phase electrical parameters of the main transformer from multiple sources; then, the three-phase characteristic multi-dimensional comparison module constructs a dual-dimensional analysis model combining vertical and horizontal comparisons to quantify the state differences of the three-phase electrical parameters; the anomaly level intelligent judgment module quantifies the degree of difference in three-phase parameters and associated risks; and finally, a two-dimensional matrix combining comprehensive difference values ​​and parameter risk levels is used to classify four anomaly levels, enabling data-driven decision-making. Finally, the personalized operation and maintenance strategy recommendation module recommends the optimal operation and maintenance strategy based on the anomaly level, main transformer attributes, operation and maintenance resources, and a recommendation rule base combined with a machine learning model.
