<p><P>PROBLEM TO BE SOLVED: To provide a wind power generator which high efficiently generates electric power additionally shows a tendency to simplify the speed control and the structure of a windmill, while suppressing in a high response the fluctuation of an outut caused by the fluctuation of a wind speed, in a wind power generation system. <P>SOLUTION: The amount of a difference between an efficient rotational speed in accordance with a wind speed from a wind speed detector 21 and a rotational speed of the windmill from a rotational speed detector 11 is input to a rotational speed controller 12, the amount of a difference between an effective power command from the rotational speed controller and effective power from a synchronous generator 2 is input to a power controller, for instance, 13, the power controller 13 controls an output of the synchronous generator in accordance with an effective power command, so as to control the rotational speed of the windmill 1 in accordance with increasing and decreasing of the output of the synchronous generator. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
