Abstract: This Wind Turbine can operate in variable speed and rotor pitch. Changing rotor pitch
4 y! ~; a. Z, F; \/ dunder variable wind speed can regulate the power capture. The doubly fed generator can operate in
0 e1 K# K  ?! P0 p( eunder-synchronous speed and super-synchronous speed according to the variable rotor speed.
Using the simulate tools, we can get the power conversion curve of the whole wind generation set.
Key words: wind generation set, variable speed variable pitch, doubly fed generator, power
conversion.
