Feasibility of power and teeter control using ailerons
- Univ. of Utah, Salt Lake City, UT (United States)
In recent years the complexity of wind turbine systems has increased dramatically. Many new turbines, and proposed designs, use aerodynamic controls, and/or power electronics to improve efficiency, eliminate overloading, and reduce fatigue loads. ADAMS, coupled with AeroDyn aerodynamic routines, developed at the University of Utah, allow for very general modeling of these systems. ADAMS allows general modeling of the dynamic system and controls, while AeroDyn allows general modeling of the aerodynamic characteristics, and wind inputs. This report presents preliminary results on the use of ailerons for regulating produced power, limiting teeter amplitude, and reducing fatigue loads on an upwind teetering rotor. For this preliminary study controllers were developed by classical methods. These controllers were then implemented in both ADAMS coupled with AeroDyn, and a modified version of YawDyn. Effect of the power control on low speed shaft power and flap moments are presented as time series and rain flow counts. Results from the implementation of the teeter control are presented as time series. It is evident from the simulations that the ailerons are capable of reducing fatigue loads, controlling produced power, and reducing teeter amplitude.
