| Abstract: | This paper focuses on the permanent magnet direct-driven wind power generation system. An overall mathematical model comprising the wind turbine, drive system, permanent magnet synchronous generators, vector control tactics, and maximum power point tracking tactics, is established. With this mathematical model, a permanent magnet direct-driven wind power system simulation model based on Matlab/Simulink is set up. Simulation is conducted on step changing wind speed as an example to examine the operation characteristics of the model after it is integrated into the grid. The simulation realizes the maximum power point tracking and the decoupling control of power for permanent magnet direct-driven wind power generation system. Results show that the system has satisfactory operation properties, and also validates correctness and effectiveness of the model established. |
