Geometric Model of Hydropower Plants: a Foundational Step Towards Creating a Hydropower Digital Twin

Abstract: A hydropower plant digital twin is a virtual model that integrates real-time data and simulations to optimize performance, monitoring, and maintenance. Its development enhances efficiency, reduces downtime, and enables predictive maintenance. Geometry generation is key, providing precise 3D models for simulations. However, creating geometries from laser scans is challenging due to complex structures, occlusions, and noisy data. This research presents a robust geometric segmentation approach, improving digital twin creation. It outlines a pipeline for point cloud segmentation, component relationships, and mesh generation, enhancing accuracy and efficiency for better decision-making and predictive capabilities in hydropower management.
