Enel – Wind Turbine Tower Monitoring with Distributed Strain Sensing

    CSI researchers fully instrumented a fully operational onshore wind turbine at the Rocky Ridge Wind Farm in Oklahoma in the Fall 2022. Analyzers using different technologies, including an analyzer that implements Distributed Acoustic Sensing (DAS), are currently collecting data daily to perform long-term structural health monitoring. Data is also recorded during storms and high winds. Several short-term tests have been conducted to gauge the capabilities of the different technologies. Further short-term tests will be conducted as bolts on the flanges go through maintenance procedures, and bolts will be removed to determine how well DAS can detect bolt torque reduction.
