“Wind Turbing Generator”
Abstract: A wind-driven generator that has improved efficiency of heating the inside of a nacelle at low outdoor temperatures in a cold region. A drive/power generation mechanism connected to a rotor head, on which blades are mounted, are received and installed in the nacelle. The nacelle has a lubricant cooling fan (14) and a generator cooling fan (17) that ventilate the inside of the nacelle to suppress a rise in the temperature in the nacelle, and also has a heating device (24) for raising the temperature in the nacelle at low outdoor temperatures. The cooling fans (14, 17) can be operated with their directions and speeds of rotation controlled. When the heating device (24) is in operation, the directions and speeds of rotation of the cooling fans (14, 17) are controlled so that the speed of air flow at a ventilation opening is substantially zero.
