Abstract
There is provided 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 mainly includes an anemometer, an anemoscope, a nacelle swiveling mechanism which turns a nacelle, and a control unit which controls the nacelle swiveling mechanism. The control unit controls the nacelle swiveling mechanism so as to swivel the nacelle based on the wind direction obtained from the measurement result of the anemoscope when the wind speed obtained from the measurement result of the anemometer is greater than a first threshold Vwhich is smaller than a cut-in wind speed V, and controls the nacelle swiveling mechanism so as to stop the swiveling of the nacelle when the wind speed obtained from the measurement result of the anemometer is not greater than a first threshold V.
