Abstract
Disclosed are a rotor for wind power generation which converts wind power into electric energy, and a wind power generation apparatus having the same. The rotor for wind power generation includes a vertically or horizontally oriented rotating shaft, a plurality of main blades conically installed to the rotating shaft so as to be equidistantly spaced apart from one another, and an auxiliary blade coupled to each of the main blades, the auxiliary blade being configured to be bent according to the direction of wind. Through this configuration, it is possible to reduce an initial starting wind velocity and achieve increased lift and drag force, resulting in an enhancement in power generation efficiency.
