Mastering Wind Turbine Tonalities with Active Vibration Control

摘要

Despite careful design of wind turbines, unwanted tonalities can occur during operation. An "Active Damping Device (ADD)" is developed, which can be retrofitted and used to reduce vibrations in wind turbines. This way the disturbing tonalities are diminished and the legal or contractually defined limit of sound emission can be met. Taking measurements and FE-simulations are necessary for dimensioning the actuators, sensors and controller, and also for the development of a technology prototype, which has proven its functionality in field tests and enabled to initiate the product development process.
