In order to promote the development of the wind power techniques in china, the research on the basal theory and the experiments on doubly fed wind power generator should be carried out. The project, which is supported by national key project “research and development on variable speed, constant frequency wind turbine generator at million-watt level”, is highlighted in this paper to transform wind energy into electrical energy maximum, and Pollution-free to repay electric back to net for main goal. This research of double-fed generator on wind turbine has great realistic-meaning. After research RD status of home and abroad large-scale wind generation set, from the two model, constant speed wind turbine or variable speed wind turbine, decided the structure and parameter of variable speed constant frequency (VSCF) wind turbine. The operating principal, why and the control system composing are also presented. The VSCF control technique is one of the most difficulties and key points in the whole wind generation system. Construct 15kW wind generation experimental system, including wind speed modeling system and variable speed constant frequency regulation system etc. Using TMS320F2407 simulation system and the SVPWM modulation technique
