Experimental research of DFIG based on wind energy conversation system

The paper introduces a full-open experimental platform for doubly-fed induction generator (DFIG), which based on wind energy conversation system. The paper starts from the working principles of doubly-fed induction generator (DFIG), then the controlling strategies of gird-connection and variable- speed-constant-frequency (VSCF) and maximum-power-point- tracking. The effects of the controlling strategies were examined in Matlab/Simulink environment. Finally, a full-open experimental platform was developed based on TMS320F28335 and PLC. Controlling strategies of DFIG were applied on the platform by DSP programming. The experiments results verified the validity and efficiency of the controlling strategies, and showed the stability of the platform.
