Abstract:
1. A method for operating a wind turbine plant comprising: providing a plurality of wind turbines, the wind turbines each having a turbine rotor including at least one blade mounted to a rotatable turbine shaft and an induction generator having a stator and a rotor coupled to the turbine shaft for rotation therewith; the wind turbines each being configurable to provide a variable amount of power; providing a control capable of communicating with the plurality of wind turbines; measuring a wind speed; determining by the control a power derating factor in response to the measured wind speed; communicating by the control the determined derating factor to the plurality of wind turbines; and adjusting the amount of power generated by each of the plurality of wind turbines in response to the power derating factor; and adjusting a cut-out wind speed of one or more of the plurality of wind turbines upward in response to the derating factor, wherein adjusting the cut-out wind speed upwards permits operation of the wind turbine plants during a high wind event.
