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 10 including operating the wind turbine 10 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 10 remains below a predefined noise emission level, obtaining an actual air density 330 related value, and applying a correction factor to the at least one set point of a wind turbine 10 parameter is provided. The correction factor is determined in dependence of said actual air density 330 related value.
