Abstract: A wind power generation system includes: blades configured to be rotated by wind; a generator configured to be driven by the rotation of the blades to generate power; a nacelle supporting the blades; and a tower supporting the nacelle rotatably. The wind power generation system is configured to receive the wind at a side opposite to a side of the nacelle on which the blades are provided. The system includes a radiator configured to dissipate heat in the nacelle through a cooling medium. The radiator is provided outside the nacelle on an upwind side of the nacelle. The radiator is provided with an intake surface thereof facing an upwind direction. A path is formed downstream of the radiator to guide the wind that has passed the radiator.

Abstract: 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.
