<P>PROBLEM TO BE SOLVED: To provide a control method and a control apparatus of a wind power generation system which performs highly reliable ferroresonance detection and effectively prevents adverse effects on an electric power system during the ferroresonance. <P>SOLUTION: A wind power generation system (100) supplies power generated by a wind power generation apparatus (1) to an electric power system (7) through a transformer (11). A control method of the invention includes a process in which the occurence of ferroresonance is detected, a process in which a protection circuit (30) is connected with the wind power generation apparatus (1) when the ferroresonance is detected, and a process in which the wind power generation apparatus (1) is disconnected from the electric power system (7) when the ferroresonance is detected over a first predetermined period T1 after the protection circuit is connected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
