A wind turbine system 10 is presented. The wind turbine system 10 includes a wind turbine tower 14, a plurality of blades 24, a rotor 22 supported by the wind turbine tower 14 and rotatably coupled to the plurality of blades 24, a torque control device coupled to the rotor, and a control system 28 programmed to predict an over-speeding time T of an occurrence of an over-speed rotor event based at least in part upon a current rotor acceleration and a current rotor speed, that cannot be compensated by an available counter-torque margin of the torque control device, and, in response, to generate pitch commands for the pitch angles of the plurality of blades 24 to avoid the over-speed rotor event. |
