WIND DRIVEN GENERATOR AND METHOD OF CONTROLLING THE SAME
摘要
<p>A wind driven generator wherein an increase in torque occurring when a system voltage is restored is suppressed to reduce a load applied to devices by the torque. The wind driven generator comprises a blade control section (22) for controlling the pitch angle of wind blades. When operations of a converter (14) and an inverter (16) are stopped by an electric power control section (21), the blade control section (22) controls the pitch angle of the wind blades so that the rotational speed of a generator (6) is equal to or higher than a synchronous rotational speed. When operations of the converter (14) and the inverter (16) are resumed by the electric power control section (21), the blade control section (22) controls the pitch angle of the wind blades so that the rotational speed of a generator (6) corresponds to a target pitch angle determined based on at least one of wind speed, the rotational speed of the generator (6), or a requested output.</p>
