Abstract
The control strategies of converters at generator and power grid sides were put forward according to the vector control method, the circuit structure and working principle of dual PWM inverters in direct-drive permanent-magnent wind power system were analyzed. The mathematical models including wind turbine model, drive train model, permanent magnet synchronous generator model and the dual PWM converter model were built. The simulation model of the wind power system was built in Matlab/Simulink software environment, and the dynamic simulations were performed. The simulation result shows that the model has good dynamic and static performance, and can control the PMSG very well. The shapes of voltage and current into the grid are close to the sine and the content of harmonic is little. The simulink result also verifies the correctness of the model and the validity of the dual PWM converter' control strategies.关键词
