According to the mathematical model of the doubly-fed induction generator (DFIG) and the field-oriented vector-transformation control technique, the control strategy of the variable-speed constant-frequency wind power generator is analyzed which can realize the decoupling control of active power and reactive power of DFIG. On the experimental platform of the DFIG system which is based on TMS320LF2812,...
The paper describes a method to control the rotor-side and grid side converters in a DFIG when subjected to the effects of network voltage unbalance conditions. In particular the control scheme of the grid side converter is adapted to assist in the control of the total power oscillations when the rotor side converter is controlling the DFIG torque pulsations. A DFIG model is implemented in Matlab/Simulink...
