<p><P>PROBLEM TO BE SOLVED: To enable a wind power generation system to continue operation or perform instant restart operation even in a system voltage drop or in an overcurrent in a system-side power converter. <P>SOLUTION: A method for controlling the wind power generation system comprises controlling the rotation speed of a rotor within a predetermined range by changing the pitch angle of a blade when any of the voltage, current, and frequency of the power system or a current detection value of the wind power generation system is found to be an abnormal value and controlling reactive power by a generator-side converter toward a synchronous generator. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
