| Bibliography: | To realize a whole set of wind power experimental platform that is both fully-open and extensible, the principles of doubly-fed induction generator （DFIG） are analyzed. The controlling strategies of gird-connection and variable-speed- constant-frequency （VSCF） and maximum-power-point-tracking are derived, and the structure of rotating speed external loop and reactive power inner loop under stator flux orientation is applied. The effects of the controlling strategies are examined in Simulink environment. A full-open experimental platform is developed based on the digital signal processing （DSP） chip of TMS320F28335 and PLC. Controlling strategies of DFIG are implemented by DSP program. The experiment results verify the validity and efficiency of the model and the controlling strategies and the stability of the platform. doubly-fed induction generator; wind power generation; full-open experimental platform; controlling strategy;grid-connection; variable-speed-constant-frequency; maximum-power-point-tracking CHEN |
