Wind power generating system

A wind power generating system, comprising:

• a plurality of plasma airflow generating units which are arranged at a blade of the wind power generating system, each unit including a first electrode and a second electrode arranged being separated from the first electrode with a dielectric film and generating plasma airflow owing to dielectric barrier discharge when voltage is applied between the first electrode and the second electrode;
• a plasma power source which supplies voltage to the plasma airflow generating units;
• a shutoff device which is connected to the plasma airflow generating units and the plasma power source;
• and
• a control unit which controls the shutoff device between a continued state and a shutoff state;
• wherein the plasma airflow generating units receive voltage from the plasma power source via the shutoff device, and the control unit stops voltage supplying to a failed plasma airflow generating unit by shutting off the shutoff device when failure occurs at any of the plasma airflow generating units.
