DFIM Grid Synchronization by Indirect Matrix Converter Using Predictive Rotor Current Control

Doubly fed Induction machine (DFIM) grid synchronization powered by Indirect matrix converter is accomplished using a rotor current predictive control approach. The DFIM network coordination is conducted with fast dynamic response. The control scheme presents rotor current control, smooth grid synchronization, fast response, with reference obtain from power position points of both active and reactive power. Grid synchronization attained by taking P-Q power position points to zero. DFIM and converter are used to predict rotor current behavior. Selecting the best-suited switching state for every suitable state of converter and implementing it the next testing time by decreasing error between reference, predictive rotor currents. Approach is implemented using MATLAB simulation and the results contain DFIM synchronization besides active, reactive power control.
