View the Complete Application at the US Patent & Trademark Office
Methods and apparatus for control and monitoring of wind turbines. Various embodiments pertain to the operational analysis of vibratory modes of the blades of the wind turbine. This real time analysis of blade modal response can be used as feedback in a control system to change the yaw angle of the hub and nacelle to capture higher power from the wind stream, change the pitch on one or more blades to reduce uneven blade loading, to identify damage to a blade, and further to identify the accumulation of ice on a blade.
