Provided is a wind power generation system that is less likely to change its cooling performance depending on the wind direction (W). In order to solve the above problem, the windpower generation system of the invention includes blades (1) adapted to rotate upon receiving wind, a generator (5) for performing a power generating operation by rotating a rotor (2) together with rotation of the blades, a nacelle (6) for supporting the blades (1) via a main shaft (3), a tower (7) for rotatably supporting the nacelle (6), a power conditioning system (8) or transformer (9) accommodated in the tower (7), and a plurality of radiators (13) disposed on an outer peripheral side of the tower (7) for cooling the power conditioning system (8) or the transformer (9). The radiators (13) positioned substantially at the same height are arranged at substantially equal intervals in a circumferential direction of the tower (7).
