Beschreibung
Zusammenfassung:	The present invention provides a wind turbine generator and a method of controlling the same which can prevent the decline in power generation efficiency even when the generator is located where the wind is not always strong. The wind turbine generator 1 mainly includes an anemometer 5, an anemoscope 7, a nacelle swiveling mechanism 20 which turns a nacelle 4, and a control unit 40 which controls the nacelle swiveling mechanism 20. The control unit 40 controls the nacelle swiveling mechanism 20 so as to swivel the nacelle 4 based on the wind direction obtained from the measurement result of the anemoscope 7 when the wind speed obtained from the measurement result of the anemometer 5 is greater than a first threshold V th1 which is smaller than a cut-in wind speed V cut_in , and controls the nacelle swiveling mechanism 20 so as to stop the swiveling of the nacelle 4 when the wind speed obtained from the measurement result of the anemometer 5 is not greater than a first threshold V th1 .
