METHODS AND SYSTEMS FOR OPERATING A WIND TURBINE IN NOISE REDUCED OPERATION MODES

摘要

According to the present disclosure, a method of operating a wind turbine including operating the wind turbine in a noise reduction mode based on at least one set point of a wind turbine parameter such that noise produced by said wind turbine remains below a predefined noise emission level, obtaining an actual air density related value, and applying a correction factor to the at least one set point of a wind turbine parameter is provided. The correction factor is determined in dependence of said actual air density related value.
