Abstract

The invention discloses a wind turbine generator set which comprises an impeller (100), a transmission system (200), a generator (300), a stator winding short-circuit device (600) and a stator power grid breaking device (700), wherein the generator (300) comprises a stator and a rotor; both stator windings and rotor windings are used for electric connection with a power grid (400); the rotor windings are in electric connection with the power grid (400) through a double-fed converter (500); the rotor is in transmission connection with the impeller (100) through the transmission system (200); the stator power grid breaking device (700) is connected between the stator windings and the power grid (400), and used for controlling on-off of the electric connection between the stator windings and the power grid (400); and the stator winding short-circuit device (600) is used for short-circuit connection with all the stator windings when the stator windings and the power grid (400) are in the off state. According to the technical scheme of the wind turbine generator set, the problem that time and energy are consumed for adjusting the blade stop angle through manual disc braking can be solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind turbine. Background technique [0002] In order to alleviate the environmental problems caused by the use of fossil energy, wind energy, as a developed clean energy, has been widely used in many fields. Among them, the use of wind energy to generate electricity is a relatively rapidly developing field. Wind turbines (referred to as wind turbines in this article) are important equipment for wind power generation. [0003] In order to ensure the normal operation of the wind turbine for a long time, maintenance personnel need to check and maintain the impeller after the wind turbine works for a set period of time. In order to facilitate inspection and maintenance work, the blades of the impeller need to stop in a certain direction after the wind turbine is shut down, for example, the extension direction of a certain blade is in the vertical downward direction....
