Abstract
A method for operating a wind turbine plant including providing a plurality of 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 turbine is configurable to provide a variable amount of power. A control is provided capable of communicating with the plurality of wind turbines. A wind speed is measured and a power derating factor is determined in response to the measured wind speed. The determined derating factor is communicated to the plurality of wind turbines. The amount of power generated by each of the plurality of wind turbines is adjusted in response to the power derating factor. A system for operating a wind turbine plant is also disclosed.
