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

摘要

Provided is a wind power generation device that is equipped with: a rotor (6) which has a blade for converting wind power energy into rotational movement; and a generator (7) for converting the rotational movement energy of the rotor into electrical power. The wind power generation device is further equipped with: a water cooling pipe (27) which is arranged between a downside stator coil (25a) and an upside stator coil (25b) that make up a stator coil (25) attached in a slot groove in a stator (23) of the generator; and a cooler (8) for cooling which passes cooling water within the water cooling pipe to remove heat that is generated in the stator coil.
