Description

technical field

[0001] The invention belongs to the technical field of wind power generators, in particular to a megawatt-level semi-direct drive wind power generator. Background technique

[0002] The low-speed permanent magnet wind turbine is a form of variable-speed constant-frequency wind turbine, which is determined by the drive structure of the wind turbine. Due to the increasingly mature power electronics technology, it allows the generator to generate electricity of different frequencies at any speed. After the power electronic device is rectified, it is then inverted and connected to the grid. Usually, in order to reduce the failure rate of the gearbox and reduce the maintenance cost, the drive chain structure adopts a low-speed permanent magnet wind turbine structure without a gearbox or a gear box speed-up, so that the structural characteristics of the unit are better, and the unit meets the long-term reliable operation of the unit. Require. Theoretically speaki...
