Provided is a wind power generation device with which power generation efficiency at low wind speeds can be markedly increased by causing a rotor to rotate at an accelerated rate. When a wind speed detection means 17 detects a predetermined average wind speed, a control means 4 performs control so that after a switching means 9 has switched a power-regeneration-type motor 3 to a motor mode and a rotor 2 has been rotated at an accelerated rate until the wind speed detection means 17 detects that the circumferential speed of the rotor 2 has reached a specified value, the motor 3 is switched by the switching means 9 to a power generator mode to generate power. When the wind speed detection means 17 again detects the predetermined average wind speed, the control means 4 repeats a control in which the switching means 9 again switches the motor 3 to the motor mode and the rotor 2 is caused to rotate at an accelerated rate. |
