ABSTRACT:
Modern engineering structures, particularly wind energy systems, face highly varying loads and harsh environments. Ensuring their resource-efficient and resilient operation is crucial, a task achieved through Structural Health Monitoring (SHM). SHM utilizes a hierarchy to detect, localize, and quantify damage, and to prognosticate the system’s lifespan. Higher-level SHM tasks, including damage assessment and performance prognosis, require the integration of physics-based knowledge and expert operator experience to complement data-driven methods. This presentation outlines treating such critical infrastructures as cyber-physical systems, where sensing, modeling, control, and networking coalesce to create dynamic digital twins. These twins are designed for continuous interaction with their physical counterparts, structured around data augmentation, modeling, expert inclusion, and ecosystem-level considerations. The data layer focuses on capturing comprehensive, informative streams, while the modeling layer uses diversified engineering models to refine data interpretation, acting as an inductive bias to enhance learning and decision-making processes. The integration of expert input adds value and supports optimal maintenance and operation strategies. At the ecosystem level, particularly for wind farms, this approach extends assessments from individual components to the entire system. The talk will explore the potential of augmented twin representations to accurately reflect current structures, predict future conditions, and recommend preventative measures.
