Provided is a wind power generation system that is less likely to change its cooling performance depending on the wind direction. In order to solve the above problem, the wind power generation system of the invention includes blades adapted to rotate upon receiving wind, a generator for performing a power generating operation by rotating a rotor together with rotation of the blades, a nacelle for supporting the blades via a main shaft, a tower for rotatably supporting the nacelle, a power conditioning system or transformer accommodated in the tower, and a plurality of radiators disposed on an outer peripheral side of the tower for cooling the power conditioning system or the transformer. The radiators positioned substantially at the same height are arranged at substantially equal intervals in a circumferential direction of the tower.
