Although the world wind generation capacity is in constant growth, the technology of wind generation is not perfect. Therefore, the research on wind power technology research is very necessary .Research on the design scheme of test platform of hardware, design wind turbine simulator, the power electronic converter device, platform detection circuit, drive circuit and control circuit and other parts, and build the direct-driven type of wind generation experimental platform. It by the generator commissioning, the analysis result has demonstrated that the design of the system is rational.
