A wind power generation system 10 of an embodiment includes a rotor 40 having blades 42, 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 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 to perform pulse modulation so that the 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 plasma induced flow.
