Definitions
- curtailment controller is adapted to operate the wind turbine facility in such a way that the electrical power supplied from the wind turbine facility equals the difference between an actual available electrical power level and the curtailment level.
- the set curtailment level may be a percentage between 0% and 100% of the available electrical power level.
- the curtailment level may be smaller than 40%, such as smaller than 30%, such as smaller than 20%, such as smaller than 10%, of the available electrical power level.
- the curtailment level may be set as a fixed power level.
- the curtailment level for a 3 MW wind turbine may be fixed to 500 kW. Thus, in full load operation the wind turbine will produce 2.5 MW whereas the wind turbine in a partial load operation will produce 500 kW below the available electrical power level.
- the curtailment level may be a percentage of an actual available electrical power level or a fixed power level.
- the main controller 107 calculates a pitch offset that corresponds to the curtailment coefficient required and sends a calculated pitch reference (including the pitch offset) to the pitch controller 108 in order to add the pitch offset to the optimal pitch angle.
- the same reduction of Cp can be obtained by changing the generator speed reference.
- this speed is often more constrained than the pitch (e.g. due to generator and/or converter considerations).
- a combination of pitch offsetting and changing generator speed reference can be used.
