The thesis presents the principle of VSCF wind Power. In this thesis, we adopt the vector control strategy of stator field-orient and gain a vector control system model of double-feedback generator.

Its control device is comprised of processing tool, energy sensor, temp. sensor, addition apparatus, regulating valve, low temp. liquid generator, and forward feed and feedback controllers.

To improve the tracking speed and control effects of the generator, the feedback system includes indirectly the future information of the tracking errors.
