Abstract


Direct-driven wind turbine has become one of the mainstream technologies in wind power generation. Studying the system structure and the control technology of direct-driven wind turbine is the basis for optimization operation of direct-driven wind turbine. The system structure of direct-driven wind turbines is analyzed and the main subsystem mathematical model of direct-driven wind turbine are established, including wind speed model, aerodynamic model, generator model, and grid side converter model. The overall model of direct-driven wind turbine is established by integration of each subsystem mathematical model. The overall model of the direct-driven wind turbine is modeled and analyzed, and the simulation results show that the direct-driven wind turbine model can accurately reflect the dynamic characteristics of the direct-driven wind turbine operation process.
