Operational Strategy
In order to improve performance and reduce life time consumption of modern wind turbines, it is essential to know about the loads that reach the drivetrain through the rotor blades. In addition, the damage status of the turbine should be known to avoid increasing repair costs of damages detected later than necessary. Detecting unwanted operational states such as pitch misalignment, yaw misalignment, imbalances or parametrization errors of damping systems will also contribute to the WTG’s health. Equipping the WTG with rotor blade condition monitoring based on oscillation and vibration analysis, the aforementioned points will be met. The key topic of the proposed presentation is showing the audience how such a CMS may contribute to lifetime extension topics in the following ways: - Collect the load spectrum for the machine to give a lifetime consumption estimation - Estimate used-up lifetime by a one year measurement to ease decision for or against lifetime extension. - Prevent unnecessary lifetime consumption to enhance extended lifetime benefits - Prevent unwanted operational states (see above) Various examples will be shown during the lesson to prove that rotor blade monitoring looks far deeper into the WTG than only looking at blades.
