AI Technical Summary
Technical Problem
Wind turbines experience rotor imbalances due to varying loads on blades, leading to uneven stresses and increased material requirements, which existing methods like manual maintenance and calibration masses are inefficient and costly.
Method used
A method for controlling wind turbines by measuring parameters, estimating rotor imbalance, and adjusting pre-tension in blade connecting wires using pre-tension adjustment mechanisms to counteract these imbalances, addressing both static and dynamic imbalances effectively.
Benefits of technology
This approach efficiently reduces rotor imbalances by optimizing pre-tension, minimizing material needs and costs, and preventing excessive wear, while providing fast and accurate imbalance correction during operation.
