Abstract
A wind turbine power generating system includes at least one wind-driven rotor for transforming wind energy into rotational motion. A plurality of turbine generators is connected to one or more wind-driven rotors. An active power curtailment controller is also provided. The active power curtailment controller is configured to curtail an actual power output of the plurality of turbine generators at a predetermined maximum output power level, the predetermined output maximum output power level being less than an aggregate nominal power rating of the plurality of turbine generators.

A method for limiting an output power level in a wind turbine power generating system to a predetermined maximum power level comprising:
- determining the predetermined maximum power level;
- providing at least one wind-driven rotor for transforming wind energy into rotational motion;
- connecting a plurality of turbine generators using the at least one rotor, each turbine generator of the plurality of turbine generators having a nominal maximum power output;
- configuring the plurality of turbine generators to provide an aggregate output power level equal to the nominal maximum power output times the number of turbine generators in the plurality of turbine generators, the aggregate power level being greater than the predetermined maximum power level when driven by the at least one rotor;
- and
- controlling the aggregate output power level at the predetermined maximum power level.
