A purely visual inspection is not sufficient to identify any issues with the rotor blades early enough and to avoid costly operational downtime. That is why the experts at Denker & Wulf AG, who are responsible for the technical oversight of the wind farm located to the south of Berlin, are very appreciative of the deployment of Bladecontrol. The Condition Monitoring system from Weidmüller continuously measures and analyses the rotor blade vibrations on 24 wind turbines. Other data and parameters, such as wind speed or the corresponding pitch angle of the rotor blades, are also used in the calculations. “Overall, this allows us to determine under what operating conditions a deviation occurs and to take steps to minimise possible causes ahead of time,” explains Joachim Fröhlich from Denker & Wulf AG. Because, in addition to damage to the rotor blades themselves, Bladecontrol can also detect aerodynamic imbalances, loose parts in the blade and hub as well as misalignments of the pitch.
