Summary
- What is new: Introduction of an efficient spatio-temporal model leveraging Physics Informed Neural Networks (PINNs) for transformer winding temperature and ageing estimation.
- Why this is important: Existing thermal models for monitoring transformer health are space-agnostic providing worst-case estimates, making HST measurement complex and expensive.
- What the research proposes: A spatio-temporal model that combines physics-based partial differential equations with data-driven neural networks to improve transformer winding temperature and ageing prediction accuracy.
- Results: The model efficiently predicts spatio-temporal oil temperature values, validated with PDE models and fiber optic sensor measurements, aiding in health management decisions for transformers.
