Abstract

Aeroelastic vibrations, caused by the complex interaction between aerodynamic forces and the structural dynamics of wind turbine blades, are a major contributor to fatigue, structural damage, reduced efficiency, and increased maintenance costs in wind turbine systems. Addressing this issue is critical for enhancing wind turbine’s operational performance, durability, and lifespan, making vibration control a key focus in the renewable energy industry. This paper investigates the Synchronized Switch Damping (SSD) modal method, a nonlinear control technique specifically chosen for its ability to efficiently mitigate aeroelastic vibrations by targeting and suppressing unwanted vibration modes. By synchronizing a piezoelectric component with a designated electrical circuit in harmony with the blade's movement, the SSD modal method provides precise and adaptive vibration control. Our study demonstrates the effectiveness of the Semi-active Modal SSD approach, achieving a notable 30.42% reduction in blade vibration. This substantial reduction enhances not only the overall performance but also the longevity of wind turbine blades, offering a significant advancement in vibration control strategies and contributing to the development of more reliable and efficient wind energy systems.
