WATER-COOLED WIND POWER GENERATION DEVICE, AND GENERATOR COOLING METHOD FOR WIND POWER GENERATION DEVICE

摘要

A wind power generation apparatus includes a rotor unit (6) including blades configured to convert wind energy into a rotary motion, and an electric generator (7) configured to convert the rotary motion energy of the rotor unit into power includes a water cooling pipe (27) arranged between a lower stator coil (25a) and an upper stator coil (25b) which constitute a stator coil (25) attached to a slot groove of a stator (23) of the electric generator, and a water cooler (8) configured to supply cooling water into the water cooling pipe and remove heat generated in the stator coil.
