AI Technical Summary
Wind turbines experience accelerated wear and increased fatigue due to mass imbalances in the rotor, leading to reduced component lifespan, particularly exacerbated by taller towers and reduced stiffness, which existing detection methods fail to effectively address.
A method and system utilizing a controller connected to various sensors to detect mass imbalances in the rotor by analyzing the mean amplitude of the 1P frequency component of operating characteristics, such as electric power output and tower acceleration, and initiating control actions to mitigate these imbalances.
The system effectively detects and minimizes the impact of mass imbalances, extending the lifespan of wind turbine components and accommodating increased tower heights and reduced stiffness, while operating in both power-generating and non-power-generating modes.
