Abstract

There is provided a wind power generation apparatus capable of suppressing power consumption in an airflow generation device, and securely suppressing flow separation on a blade surface, thereby improving efficiency. A wind power generation apparatus 10 of an embodiment has wind turbine blades 32 each having, in a chord length direction, a base blade 51 fixed to a rotation shaft and a front divided blade 50 fixed in a pivotally adjustable manner, a first electrode 41 and a second electrode 43 which are disposed separately via a dielectric 42 on a blade surface of at least one of the base blade 51 and the front divided blade 50, and a discharge power supply 61 capable of applying voltage between the first electrode 41 and the second electrode 43.
