ABSTRACT:
An object of the invention is to reduce stop time of a wind turbine generator caused by icing on a wind turbine blade in the wind turbine generator. The invention provides the wind turbine generator including an ice detecting unit for detecting an amount of icing on a wind turbine blade, wherein an operation mode is switched to a no-load operation mode with no power being generated in a case where the icing amount detected by the ice detecting unit exceeds a first predetermined value, and an icing amount is detected by the ice detecting unit in a state where the apparatus is operated in the no-load operation mode.
