PROBLEM TO BE SOLVED: To provide a wind power generation system and a control method for the same capable of optimization of a flow on a blade surface and improvement of power generation output.SOLUTION: A wind power generation system 10 of an embodiment includes a rotor 40 having a hub 41 and blades 42, a nacelle 31 for pivotally supporting the rotor 40, a tower 30 for supporting the nacelle 31, an airflow generation device 60 provided in a leading edge of each of the blades 42 and having a first electrode 61 and a second electrode 62 which are separated via a dielectric, a discharge power supply 65 capable of applying a voltage between the electrodes of the airflow generation device 60, and a control unit 110 controlling the discharge power supply 65. The control unit 110 controls the voltage from the discharge power supply 65 to perform pulse modulation so that a value of a relational expression fC/U is 0.1 or larger and 9 or smaller where f is a pulse modulation frequency of the voltage, C is a chord length of the blades 42, and U is a relative velocity combining a peripheral velocity of the blades 42 and a wind velocity, so as to generate a plasma induced flow. |
