Abstract
A wind turbine includes a wind turbine blade and a foreign matter detection device disposed on the wind turbine blade for detecting an accumulation of foreign matter on the wind turbine blade. The detection device automatically sends an indication when a threshold level of foreign matter accumulation is detected. A wind farm control system can display a color coded live plot of all wind turbines in a wind farm system, with a indication of foreign matter accumulation for each turbine.
Claims20
A wind turbine comprising:
- a wind turbine blade;
- and
- a foreign matter detection device disposed on the wind turbine blade for detecting an accumulation of foreign matter on the wind turbine blade.
A wind farm system comprising:
- a plurality of wind turbines, each of the wind turbines comprising:
- a wind turbine blade rotatable about an axis upon an impact of a wind flow on the wind turbine blade;
- a foreign matter detection device disposed on the wind turbine blade for detecting an accumulation of foreign matter on the wind turbine blade;
- and
- a controller configured to receive foreign matter accumulation data from the foreign matter detection device.
A method of monitoring foreign matter accumulation on a blade surface of a wind turbine blade, the method comprising:
- receiving an indication of a level of foreign matter accumulation on the blade surface from a foreign matter detection device disposed on the blade surface;
- and
- determining if the indicated level of foreign matter accumulation exceeds a threshold level.
