Speech Title: Artificial Intelligence Application for Condition Assessment of High Voltage Power Transformer using Health Index
Abstract: Power transformers are vital and costly components of the electrical power system. Ensuring the reliability and safety of these systems necessitates consistent monitoring and maintenance of transformers. The Health Index (HI) is a widely used method for assessing transformer conditions. This study models a method for calculating the transformer Health Index using artificial intelligence (machine learning) algorithms. The developed method considers transformer operating voltages and integrates dissolved gas analysis interpretations using multiple methods (Multi-methods). The findings indicate that higher operating voltages correlate with faster rates of transformer condition degradation. The non-conventional method with machine learning demonstrates higher prediction accuracy and reduces calculation subjectivity without requiring expert involvement. The Random Forest algorithm outperforms others in failure prediction based on DGA results, while Neural Networks excel in predicting HI categories with numerous input parameters. The application of the Synthetic Minority Oversampling Technique (SMOTE) improves model performance by balancing dataset classes, achieving a prediction accuracy of 99% for DGA and 97% for the Health Index.
