Wind turbine generator

Abstract

A wind turbine generator capable of enhancing starting performance of the wind turbine generator when the outside air temperature is low and capable of securing temperature adjusting ability of a generator set in a wide outside air temperature range is provided. A wind turbine generator includes a nacelle (3) for accommodating a generator set (11, 12, 14) that generates electricity by rotation of a rotor having a plurality of blades, a ventilation opening (51) provided in a wall surface on a wind upstream side when the nacelle is normally operated, and a heat exchanging unit (13) disposed in the ventilation opening (51) to exchange heat between an outside air and a lubricant of the generator set (11, 12) such as an lubricant oil or cooling water.
