Setting a restricted power output of a wind turbine which is independent of wind speed

摘要

590222 Disclosed is a method for curtailing electrical power supplied from a wind turbine facility (101) to an associated power supply grid. An available electrical power level is determined from the wind turbine facility (101) and a curtailment level is set for the wind turbine facility (101) which is independent of wind speed. The curtailment level that is set is a percentage of the available electrical power level. The wind turbine facility (101) is then operated in such a way that the generated electrical power supplied from the wind turbine facility (101) equals the difference between an actual available electrical power level and the curtailment level.
