| Abstract: | The status of wind turbine gearbox system in the cold stand-by was researched, taking a 1.5 MW wind turbine as an example. According to the calculated result of the heating and the cooling of the gearbox system, the temperature in each time of a period was estimated, and the main reason that the gearbox stand-by was difficult at low tempeature was explained. Some improving projects on the cold stand-by were given. |
