Abstract

The present invention relates to a wind power generator which charges and uses electricity generated by the force of the rotation of rotary blades. More particularly, the present invention relates to a wind power generator having an auxiliary blade, in which blades are installed at both sides of the generator and the auxiliary blade is interposed between the blades so as to increase rotational force with the same wind power and simultaneously control the rotational force of the blades when a strong wind blows, thus improving power-generation productivity and simultaneously preventing damage to the blades when the strong wind blows so as to improve the durability of the blades.
