SYSTEM AND METHOD FOR IMPROVED OVERSPEED MONITORING OF A WIND TURBINE OPERATING AT REDUCED ROTOR SPEEDS

A method for overspeed monitoring of a wind turbine may generally include monitoring an actual rotor speed of the wind turbine while the wind turbine is operating at a current speed setpoint and referencing a dynamic overspeed setting for the wind turbine. The method may also include determining a f...

Zusammenfassung:	A method for overspeed monitoring of a wind turbine may generally include monitoring an actual rotor speed of the wind turbine while the wind turbine is operating at a current speed setpoint and referencing a dynamic overspeed setting for the wind turbine. The method may also include determining a final overspeed setting to be applied for the wind turbine based on a comparison between the dynamic overspeed setting and a predetermined overspeed setting for the wind turbine. In addition, the method may include comparing the actual rotor speed of the wind turbine to the final overspeed setting, and when the actual rotor speed is equal to or exceeds the final overspeed setting, initiating a control action to adjust an operation of the wind turbine in a manner that reduces the actual rotor speed.
