Abstract


Although the world wind generation capacity is in constant growth, thetechnology of wind generation is not perfect. This dissertation is a part of the projectof " Direct-driven Wind Generator Operation Performance and Control Technologyof Fault Ride Through， which is natural science fund program in gansu province.Choose the DSP TMS320F2812as the core device, and design a set of small powerwind generation test platform.Firstly, this paper introduced the purpose and significance of wind generation.Then the present situation of research was introduced both domestic and abroad.Analysis basic theory of direct-driven wind generation, the permanent magnetsynchronous generator and PWM converter is to analysis in detailed, and establishedmathematical model of converter in three-phase static coordinate and two-phaserotation coordinates.Secondly, research on the design scheme of test platform of hardware, designwind turbine simulator, the power electronic converter device, platform detectioncircuit, drive circuit and control circuit and other parts. Through the design offunction module and choose components, we use the2812DSP as the core device,and build the direct-driven type of wind generation experimental platform.Thirdly, focus on the method of control to do research in dual PWM converter,and the generator side PWM converter was controlled based on the rotorflux-oriented, the control of grid-side PWM converter is based on gridvoltage-oriented. The converter system is based voltage and current dual closed-loopcontrol. Study engineering design method of calculate regulator. Design the softwareof system in CCS3.3.Finally, test platform by the machine commissioning, the test analysis result hasdemonstrated that the design of the system is rational.
