Background
Traditional methods of creating layout drawings, taking measurements, and gathering data to recreate three-dimensional (3D) environments are cumbersome, especially in high-voltage environments. Simple measurement methods may not be feasible due to electrical clearances and safety parameters. Non-contact triangulation methods are sensitive, manual, and time-consuming. A more efficient and safer method has emerged. Mobile mapping systems automatically collect LiDAR (light detection and ranging), imagery, and geospatial data to create dimensionally accurate 3D digital environments. Mobile mapping technologies can scan a 360° field of view in just minutes, demonstrating remarkable speed and accuracy. Software systems process these data to create dimensionally accurate 3D digital twins. Terrestrial scanners boast millimeter-level accuracy, while mobile-based technologies scan large environments quickly. The technology’s speed, accuracy, and ease of use enable more frequent and widespread use in substation applications.
This project leverages the latest commercial-off-the-shelf 3D scanning technologies to test and evaluate their ability to support utility substation applications. Integrating these tools can improve the asset lifecycle process in the following ways:
- Substation Site Analysis and Planning: 3D scanning technology can provide accurate data about the terrain, surroundings, and existing infrastructure, enabling engineers to make informed decisions during the planning phase.
- Substation Design: Engineers can use 3D scanning data to create precise models and simulations, optimizing the design process and ensuring seamless integration of substation assets.
- Substation Construction: 3D scanning facilitates more accurate construction planning and streamlined project management, reducing errors, improving timelines, and saving costs.
- Substation Maintenance and Repairs: By creating a digital twin of the substation, 3D scanning technology aids ongoing maintenance by providing a comprehensive understanding of the layout and infrastructure, enabling easier identification of potential issues and effective maintenance planning.
