| Abstract |
The control of an induction machine driven by a wind turbine suupplying energy to the grid is presented. Two back-to-back voltage source PWM inverters are used to interface the machine and the grid voltage. The machine currents are controlled using vector control techniques ensuring flux and torque control. Machine torque control is used in order to track an optimum rotational speed for maximum wind energy capture. The control of the DC-link voltage is accomplished by transformation of ac quantities to the rotating voltage reference frame, feedforward compensation and control of the E² norm in order to obtain a linear plant. This strategy can effectively be used for reducing the value of the DC link capacitor. The use of other techniques, such as duzzy logic controllers, is also discussed. |
