PROBLEM TO BE SOLVED: To provide a wind power generation device very efficiently generating electric power while controlling output fluctuation due to wind speed fluctuation in a wind power generation system in quick responses, and simplifying speed control and a structure of the windmill. SOLUTION: A difference between efficient rotating speed corresponding to wind speed detected by a wind speed detector 21 and rotating speed of the windmill detected by a rotating speed detector 11 is entered into a rotation speed controller 12. A difference between effective electric power command from the rotating speed controller and effective electric power from a synchronous generator 2 is entered into, for example, the electric power controller 13. The electric power controller 13 controls output of the synchronous generator 2 according to the effective electric power command to control rotating speed of the windmill 1 according to increase and decrease of output of the synchronous generator 2. |
