SHM.Blade® is a tried and tested system, certified by DNV GL, that can detect such structural damage on rotor blades at an early stage. For this purpose, a reference condition is used which is determined individually for each rotor blade fully automatically and without external intervention immediately after the activation of SHM.Blade. Such a blade-specific learning phase ensures high sensitivity to damage - despite the mass and stiffness tolerances caused during production.
When the learning phase is completed, the system continuously calculates condition indicators, which provide information on the current condition of the blade at all times. By means of a two-level warning and alarm concept, the wind turbine control system can react and subsequent damage can be avoided.
