Digital SHM: Enhancing Structural Health Monitoring with Digital Solutions

© GreenWITS
Context

Structural monitoring typically relies on Structural Health Monitoring (SHM) systems, which are installed on a small fraction of assets within a farm. These systems use various structural sensors whose data is analyzed periodically or continuously to evaluate the condition of the structural components. However, this conventional approach faces two significant challenges: high initial and operational costs for implementing and maintaining SHM systems, and limited sensor coverage - both in terms of the number of monitored turbines and the quantity of measurement points per turbine.

GreenWITS Solutions

To overcome these limitations, GreenWITS has developed a method that couples measurements obtained from a conventional SHM system with advanced digital models. This method uses a limited number of conventional structural sensors, whose measurements are augmented with digital models, in particular physical models of the assets and the farm. The method enables the generation of a large number of structural indicators at any location on the structure and any asset in the farm from a limited number of sensors compared to a conventional SHM system.
