Wind turbine, Brand Name : ADDNEW

we are offering wind turbine.
an7282-2000 wind turbine consists of main components such as blade, hub, nacelle, pitchyaw drive, pm synchronous generator, converter, control system, and tower etc.
a: pm synchronous generator:
ã�â¯ã¯â¿â½ã�⬠the generator is a multi-pole permanent magnet generator and is directly mounted to the hub.
ã�â¯ã¯â¿â½ã�⬠permanent magnet takes care of the rotor excitation so no external filed excitation is needed. this implies that the generator losses would be reduced by 25% compared to a regular wound generator.
ã�â¯ã¯â¿â½ã�⬠the stator windings are vacuum impregnated under pressure.
ã�â¯ã¯â¿â½ã�⬠inside of the generator, dried and filtered air is circulated. this assures an equal temperature distributed in the generator. as inside of generator is over-pressured, dust and salt particles cannot enter into the generator though a little leakage occurs through the seals.
b: converter
ã�â¯ã¯â¿â½ã�⬠the main circuit of mv class permanent-magnet synchronous direct-drive wind turbine converting system adopts ac-dc-ac structure, variable frequency ac from the pm synchronous generator can be rectified converted into constant frequency ac by converter, then fed into the grid through transformer.
ã�â¯ã¯â¿â½ã�⬠full-power converter control the wind turbineã�â¢ã¯â¿â½ã¯â¿â½s power according to the function relation between output powers and rotating speed and make the power stable in a related value(when the wind speed is bigger than the rated value).
