Abstract

A wind turbine foundation has been monitored for one year in order to assess the effectiveness of a repair work carried out in 2017. A number of displacement transducers have been installed together with strain gauges and accelerometers to understand the turbine dynamic behavior.

One year of data is now available coupled with the machine working parameters (power, wind intensity/direction). These data have been analyzed in order to identify any possible evolution in the turbine behavior and therefore highlight any deterioration in the foundation behavior (stiffness reduction). This paper describes the data analysis taking into account all environmental effects and the associated bias on the measured data. Results show a stable behavior of the turbine foundations through the whole year proving the effectiveness of the performed repairs.
